Samsung Galaxy S4 Formally Announced in the USA

Samsung have formally announced and dated their new flagship smartphone, Samsung Galaxy S4, and announced that it will reach American hands on April 30th. It arrives just in time to tempt those who haven\’t yet reached for the HTC One and are waiting it out to see what Samsung pulls out of its magician\’s top hat, as the company has built a reputation for innovation and quality over the years and has released a string of popular handsets.

\"Samsung

Not that other manufacturers haven\’t, of course – but you\’d have to feel a little stressed knowing you were facing off against this beast of a machine. With two gigabytes of RAM, a 5\” screen (a cheeky wink towards the current 4.7\” trend) and full HD on its display, the Galaxy S4 is a serious contender for being branded the best handset of 2013.

The impressing thing about Samsung\’s launch will be its inevitable competition with other handsets as it sets out to demonstrate just what sets the manufacturer apart. Then again, given Samsung manufactures the tech for at least one other major competitor, it\’s worth thinking about the level of capability they possess when it comes to building smartphones, tablets and the like.

The initial reviews are starting to come in, although they\’re no more than first looks, but the initial impression from critics is that they\’re, well, impressed. There\’s a lot to compete with here, bearing in mind that the Galaxy S4  follows on from the SII and S3, both extremely popular high-quality phones in their own right, both of them still happily in use by Samsung fans even now, which is unusual for the smartphone market.

The S4 itself has many noticeable improvements, such as facial recognition technology, an improved camera, and a larger and higher-resolution screen. It also comes with an extremely thin layer of glass over the screen itself, which helps keep the form factor of the device down while allowing you to feel like you\’re interacting with the screen more directly than on handsets with thicker glass.

There are other little innovative touches, too, such as Smart Look, which pauses video when the phone works out you\’re not looking at the screen, Sound and Shot, which records nine seconds of audio with the photo you\’ve just taken (not a unique feature but a nice one nonetheless), and of course the quality of the camera itself whether you\’re recording video or taking snapshots of the world around you. The S4 indeed has quite the formidable feature set, and when it hits the USA at the end of April it will be interesting to see how the competition reacts to such a desirable phone.

It seems like this year is definitely the year of smartphones that are set to push the bar regardless of which manufacturer they\’re from, and as Samsung and HTC step up as rivals to Apple in terms of innovation and quality, it\’ll be exciting to see who comes out on top in the end, especially if it drives these companies to produce more impressive handsets in an attempt to beat one another.

Editor\’s note: Samsung Galaxy S4 will hit the Philippine market this week and local telcos will have their separate launches in the coming weeks, too, so stay tuned for more information.

TweetDeck Alternatives for Android and iOS Power Users

TweetDeck for Android, iOS and Air

When Twitter abandoned TweetDeck for Android and iOS last week to focus on the web version of the popular Twitter client, I was not surprised. If you look at the frequency of updates since Twitter acquired TweetDeck, the mobile apps were last updated on 4th quarter of 2011 but the HTML 5 and Chrome app managed to get regular updates. It seems they have neglected Android and iOS clients completely from the beginning. So for Twitter to say that “over the past few years, we\’ve seen a steady trend towards people using TweetDeck on their computers and Twitter on their mobile devices,” is a well-coordinated plan. More users would have used TweetDeck on mobile if only Twitter exerted enough effort on its development. Obviously the priority is still on Twitters\’ very own client.

The Air version was upgraded to HTML 5 (basically the same as Chrome) when Twitter acquired TweetDeck. It is not the old TweetDeck Air that we used to love or hate. Version 0.38.2 is the last Adobe Air version.

I didn\’t miss the Adobe Air version too much because I stopped using it years ago. I don\’t know why some people can\’t move on. The only feature that I miss in  TweetDeck Air, which is still useful today, is the \”Include @replies from friends to others\” feature that enables you to see all conversation even if you are not following the friend of your friends. If you want to stalk your friend or monitor all conversation happening on Twitter then you\’ll need it but why meddle in between conversations when it doesn\’t concern you? I don\’t have a strong opinion on why you should bother so I am fine without it.

\"TweetDeck

TweetDeck HTML 5 and TweetDeck for Chrome is the best Twitter client for desktop because it doesn\’t hog your computer resources and most of the features of the original TweetDeck Air is still there with additional innovations like the combined timeline columns for multiple accounts.

TweetDeck Replacement for Android

I consider myself a Twitter power user. I have several accounts and I seldom use the main timeline as my source of updates. Since I use lists to segment the people I am following it is  also the main reason why I don\’t use Twitter for Android as my main Twitter client. It seems that Twitter does not highlight the importance of lists anymore but it is one of the most useful feature Twitter ever has. I rely too much on lists that I consider apps without an option to remove the \”home\” timeline, to replace with other lists, inferior compared to those apps supporting this feature. TweetDeck doesn\’t have the option to remove the main timeline but at least there is an option to stop it from updating. I think the only reason I keep on using TweetDeck is due to its individual column refresh interval and alert settings. The HTML 5 and Chrome app inherited this feature but for me, it is much more useful in the mobile app.

As a back-up plan I have been using other great TweetDeck alternatives since last year.

These are my top three:

These three are very easy to customize and they have lots of features perfect for meticulous Twitter users like me.

Boid has a default Holo dark theme which is my preferred theme in all my Android apps Ubersocial and Plume can be customized to have dark themes similar to Holo. I would like to include Hootsuite in my preferred Twitter client for Android but the Android version is unstable in my experience; it pales in comparison to the iOS version.

TweetDeck Replacement for iOS

\"Tweetdeck

Speaking of iPhone, I am not a heavy user of Twitter in iPhone or iPad partly because there is no free Twitter app that is good enough for me in iPhone or iPad and partly because I can do so much more in Android twitter clients that there is no need for me to use any Twitter on iOS. However if I would choose a free Twitter client that would be Hootsuite and for the paid client I\’ll choose Tweetbot.

How about you? What will be your primary Twitter client for mobile?

Twitter vs. Instagram – The Unanimous Decision

I tested  the newly updated Twitter app in iOS and Android since yesterday and right away I knew that Twitter is far behind the competition.

The short answer to which is better, Twitter vs. Instagram — is obviously Instagram by unanimous decision. In every review you\’ll read most pundits reason that Twitter is only following the footsteps of Instagram which made a new category of social network full of filtered photos.

Since I have already established that Instagram is still better, what\’s cool in Twitter\’s own photo filter features anyway?

Twitter vs. Instagram Filters

Twitter is using Aviary to process their photo manipulations… and they only have 8 filters at the moment. In contrast, Instagram has a whooping 18 free filters. Comparing Twitter filters vs. Instagram filters, Twitter is only using bare minimum at the moment and not even using full power of Aviary SDK. Aviary has a total of 30 filters and 12 of them are free while the other 18 are available via in-app purchase. Not to mention Aviary has more options to adjust brightness, warmth, contrast, saturation and sharpness. Maybe Twitter is only paying for the bare minimum features just to see how their users will use photo filters. Depending on the result, it\’s possible that Twitter might roll out new filters in the near future too.

Below, I have used an image that is vivid enough and has a fair distribution of highlight (white) and shadows (black), as well as mid-tones (gray). You can see how the picture is enhanced using all the Twitter photo filters.

\"Twitter

The interface  is clean and very intuitive.

The first button is for  \”auto-enhance\”, the right is crop option where you can crop and just pictures similar to the square ratio similar to Instagram, and the center button is the filter options.

I like that you can have a bird\’s-eye view of the filters and choose which filters look best immediately. You can\’t do this in Instagram because it forces you to select a filter one at a time only.

Instagram and Twitter War

Since Instagram remove the Twitter card support, you can only see link inside your Twitter feed. No more pictures in the stream like it used to be. Some 3rd party apps still support the embedded photos including Twitter\’s very own Tweetdeck but we don\’t know how long it will support it.

What\’s great about Twitter picture service is that is shown in embedded tweets.

Instagram on the other hand will only look like just any another links.

Embed Work-around?

Well, if you like Instagram pictures so much you can still use Instagram as your primary photo filter app, and then attach it to your Twitter post manually. There is an extra step and it will result to uploading the photo twice. One in  Instagram, then another one in Twitter as a duplicate.

I don\’t like the minimal choices of photo filters in Twitter now but the good news is, you can use any photo filter apps that you want and share it in Twitter. For instance, if you are one of the Instagram haters, there\’s plenty of choices around – including Aviary which has more advance features available in both Android and iOS.

If you are looking for ways to embed Instagram photos in your blog, you\’re lucky because WordPress 3.5 supports Instagram oEmbed. I haven\’t tested it yet but it\’s included in WordPress change logs as a new feature.

I have included the official Twitter photo filters video below. Let me know what you think of Twitter vs. Instagram and its short-term/long-term effect in your online community.

This article is a guest post from Michelle, a tech writer in UK.

Despite having strong competition from iPhone 5, Nokia Lumia 900, HTC One X and Nexus, Samsung Galaxy S3 still serve to be one of the best gadget ever because of its outstanding features and excellent apps.

\"Galaxy-S3\"

The S3 is built up with a 4.8-inch large display and its slim design aid to present more comfort while handling and operating the device. It comes up with a glossy finish along with a good multi-touch facility. When compared to its predecessor Galaxy S2, Samsung Galaxy S3 has been upgraded ahead of its time in terms of display, weight, and other features.

Best 15 Travel Apps for Android and iOS

Below are 15 travel apps for Android and iPhone that my wife and I use when travelling. I use Android as my primary phone while she uses iPhone. From time to time we swap phones because I don\’t get all the apps I want in Android and sometimes it is the other way around.

These apps are all available in both Android and Apple iOS devices. I hope that these can make your travel easier and more fun.

Travel Apps for Android & iPhone

\"Kayak

1. Kayak

When booking deals for hotels, flights and cars, Kayak gives a lot of options even for most remote place that I tried booking. I mainly use this for researching accommodations but it has other features that will delight seasoned travelers.

It can also consolidate your travel plans in \”My Trips\” which can be done easily  by forwarding booking confirmation emails to [email protected]

Kayak also conveniently gives you a ready-made packing list that you can use to track every items you need to pack to make sure you don\’t forget anything.

Other features include flight tracker, price alerts, airline directory, airline fees, airport information (powered by  GateGuru), currency converter and inflight GPS tracking.

Two features that is existing in iOS but lacking in Android are Tours and Attractions, which gives you a list of places of interest to go with tour guides, and Buzz which lists flight search trends.

\"Tripit

2. Tripit

Even before Kayak added \”My Trips\”, TripIt has been parsing airline tickets, hotel reservations, car rentals receipts and other confirmation emails to create your master itinerary. It is better in organizing your itineraries because it makes them available in one place and you can share it with family and friends who uses Tripit too.

When you add people in your Inner Circle, you can automatically share your complete itinerary with other people using Android or iOS — it is a great way to inform anyone in your Inner Circle your whereabouts.

\"Flight

3. Flight Track

If you do a lot of business travel, you need this application. It has real-time status for gates, delays and cancellation. You can also find alternate flights and view seat maps.

\"Hostelworld

4. HostelWorld

If hotels is not your thing and you prefer back-packing then HostelWorld is the perfect app to get a cheap place to stay.

\"XE

5. XE Currency Converter

It was tough choosing the best free currency converter.

Before sticking with XE Currency Converter, I was using Oanda Currency Converter. It was great but it can only show 1 currency at a time and there was no log when was the latest exchange rate update.

So I switched to XE Currency Converter because it has live exchange rate and I can refresh it anytime I want.

\"Expensify

6. Expensify

This app lets you log expenses, scan receipts, log time with an hourly rate and use mileage, odometer or gps as reference to any bill. Scanning receipts is as simple as taking picture of the receipts and letting Expensify process it using Smartscan that  automatically logs properly whatever value found in the receipt using OCR. The free version is limited to 10 free smartscans a month but when you upgrade to pro, each scans is priced at 20 cents each.

\"Lemon

7. Lemon

If you don\’t need to log mileage then Lemon is a simpler alternative to Expensify. It also lets you process receipt using their OCR technology. You get 25 free receipt processing a month. With a pro account, you can even process line item details – i.e. every item on your grocery receipt will be recorded not just the high level expense value.

On top of this, Lemon can also keep a digital copy of your cards — not just credit cards mind you. It works on IDs, loyalty and membership cards. I don\’t know if Apple copied the idea of Lemon but before Apple\’s Passbook for tickets and coupon, there was Lemon for cards.

\"Foodspotting

8. Foodspotting

When you go places, you need to find recommended great local dishes, not just restaurants. What\’s great about this app is that it\’s all about dishes. You can find the best food nearby and get recommendations from people you follow.

\"Foursquare

9. Foursquare

Since Foursquare upgraded their app to more than a check-in app, I started using it to find recommended places using the Explore feature. You can search for specials, trending, food, coffee, nightlife, shops, sights, outdoors, arts and entertainment. Some of the tips are very helpful to get the most out of the scenic spot or trendy places.

For food and beverages, Foursquare is starting to function like Yelp but unlike Yelp, Foursquare is available in many places, mostly generated by users. You also don\’t get a menu; you simply get tips on what to eat from random users who check-in on those places.

\"Triposo

10. Triposo

I only discovered Triposo lately and it is has travel guides for most countries. The best part is that it is free and it works offline. No need to worry about data access on remote places without signal. You don\’t need to worry about roaming charges with this app.

Each travel guide you install presents you a travelpedia where you can learn the basic history, culture, architecture  and music of the country. It also has some phrasebook that can be handy. It has popular destinations with guides on what you can see and don on those places.  It even has \”eat, drink and sleep\” section to find where to hang out at night, drink coffee and get hotels accommodation with all the contact details and address that you can use to get there.

\"Tourist

11.  TouristEye

This is another app that can work without internet connection. When you add a place in your trip, it will download an offline copy of all the information of the city that you have chosen. That includes maps, all the attractions, restaurants, entertainments, tours and transport information.

It doubles as itinerary planner and travel journal too.

\"Google

12. Google Translate

The latest version of Google Translate is now essential to any traveler going to a foreign country with a foreign language. You can take picture of any sign and with Google\’s character recognition it can translate any language to english.

\"Google

13. Google Local

When you install Google+ in Android, you also get Google Local. It replaced Google Places. This app is actually merged with Google Maps, Navigation and Latitude in Android because it is contained in one unified application. However,you need to install Google Local separately in iOS.

Zagat ratings are incorporated in Google Local because Google purchased Zagat, remember? I still find the 30-point scale unusual but at least it gives you an overview on how good a place is. Google Local also aggregates other reviews from sites like TripAdvisor so you can\’t find TripAdvisor in this list as it is redundant already.

Google Local is also linked to Google+ Local Pages so you can use your Google+ circles to get recommendations.

\"Google

14. Google Maps

Too bad iOS replaced Google Maps in iOS6. It is still the most detailed map available for free and it has live traffic information where it is supported.

Indoor maps for selected places are particularly helpful in navigating unfamiliar buildings. In Android you can also cache map area so you can use Google Maps even if there is no network signal. This is very important if you are going to an island or rural places.

I can\’t think of any maps with chock-full of features that is so easy to use. Good news for iPhone users, you can still use the mobile web version of Google Maps.

\"Siri\"

15. Google Now / Siri

We call them personal assistant and knowledge navigator apps. However, these apps can be your travel buddy too.

Google Now is only officially available in Android 4.1 Jelly Bean. It incorporates several features from different apps and made them accessible using voice commands as well location triggers. Some of it features includes traffic guide, public transit information, next appointment notification, flight delay forecast, place recommendations, weather, translation, currency conversion and time conversion.

Siri has almost the same set of features but Google Now is location-aware while Siri is not. For travelling, Google Now gets an edge because it doesn\’t require voice input all the time but when you\’re bored while on the road, Siri could be fun.

Google Now and Siri are applications that can seriously change the way we use information around us.

If data roaming is not an issue then Google Now and Siri is the perfect companion in any place you wish to go. Of course, given the choice I would still travel with my love ones.

So now, it\’s your turn. Let me know what\’s your favorite travel apps for Android or iPhone.

Kindle Comparison Chart: Kindle Fire HD vs. Others

\"KindleIt was already expected that Amazon will release a bigger tablet, purportedly called Kindle Fire 2, in order to compete with the bigger tablet iPad. Today, after about a year of Kindle Fire announcement, Amazon introduced their new tablet line up. Interested how the flagship model Kindle Fire HD compare to other tablets?

Last year I blogged about Kindle comparison chart to guide users in buying Kindle Fire. I have updated it now so you will see the new Kindle Fire HD comparison charts below.

Kindle Comparison Chart (all variety)

There are 7 new Kindle models announced today. In Kindle Fire HD family, there are 4 — namely the Kindle Fire (2nd gen)Kindle Fire HD 7\”, Kindle Fire HD 8.9\” and Kindle Fire HD 8.9\” 4G LTE Wireless

Kindle Fire (2nd gen) and Kindle Fire HD 7\” will be available starting September 14 while Kindle Fire HD 8.9\” variants will be available only on November 20 so you better pre-order now to reserve your place in line.

If you are not sure what is the best Kindle for you, use the chart below to compare all the latest Kindle models. At the time of this writing the older models, Kindle Touch and Kindle Touch 3G are already unavailable as they are already succeeded by  Kindle Paperwhite and Kindle Paperwhite 3G respectively. Amazon touts that the Paperwhite models are the world\’s most advanced e-readers as it offers high-resolution, high contrast, built-in light and 8-week long battery life.

Interesting enough, the good old Kindle Keyboard and Kindle Keyboard 3G are still available and not refreshed or upgraded this time.

\"Kindle

Let\’s move forward on the top of the line model Kindle Fire HD and compare it to the premium tablet brands in the market.

Kindle Fire HD 8.9\” vs. iPad vs. Galaxy Note 10.1 vs. Microsoft Surface

Dimension

In terms of screen size, Amazon Kindle Fire HD is only 8.9 inches diagonal, which makes it smaller than 0.8 inches compared to Apple iPad\’s 9.7 inches. In fact, Kindle Fire HD is a bit smaller than Apple iPad (3rd gen), Samsung Galaxy Note 10.1 and the upcoming Microsoft Surface.

To think that Kindle Fire HD is only 8.8mm thick, Amazon must have targeted iPad 2 which is also 8.8mm.

Screen

When iPad 3rd gen was released its 2048×1536 resolution seemed unnecessary. However, knowing Apple is a trend-setter I have predicted that consumers will look for more personal computing devices with better display. And now, here is the Kindle Fire HD  with 1920×1200 resolution packed in 8.9-inch IPS LCD. Many video enthusiasts should be happy because it has 16:9 screen ratio suitable for widescreen movie playback.

In retrospect, if you think Apple\’s retina display is overrated then how about the latest trend in HD TV? The new wave of digital TVs are already showcasing 4K resolution. Who knows how soon 4k will be the standard screen resolution?

\"Kindle

Price

According to Jeff Bezos, \”We want to make money when people use our devices, not when they buy our devices.\”

Price is one of the best differentiating factor in buying Kindle Fire HD and perhaps this alone can persuade you to buy Kindle Fire HD.  As you can see in the Kindle comparison chart, it shows that the 8.9-inch Kindle Fire HD starts at $299. That is a whopping $200 difference compared to the 3rd gen iPad. Even with the extra $200 change you can still buy the entry-level Kindle Fire HD 7\” which starts at $199.

Other Features

While Amazon can\’t compete with the number of apps in Apple Apps Store, it compensates for the vast library of movies, TV shows, songs, magazines, books, audiobooks and popular apps that users can buy and consume. There is unlimited cloud storage for all your purchased Amazon content.

It is a little disappointing that Amazon did not even try to put a decent back camera in Kindle Fire HD. This reinforced the notion that all Kindle Fire devices are made for consuming Amazon products and not for producing content. My understanding here is that Amazon wants its consumers to finish reading books or complete watching TV series and audiobooks instead of allowing them to use Instagram to take pictures which doesn\’t add any benefit to Amazon at all. If you get pass this small limitation then everything in Kindle Fire HD is perfect.

Even without a back camera, the front-facing \”HD\” camera can be used for free Skype calls and audiophiles will surely enjoy the Dolby audio virtual surround sound.

Further more, Amazon is introducing Kindle Freetime which allows you to control your kid\’s access to Kindle Fire HD tablet. As a parent you can limit time for reading books, watching videos, using apps, etc.

New users also get one month free access to Amazon Prime for unlimited, instant streaming of thousands of popular movies and TV shows.

Last Words

I hope the 2 Kindle comparison charts above helped you compare the current Kindle model line up and other existing tablets.

Do you think Amazon Kindle Fire HD hits all the sweet spots? Is it a true Apple iPad contender?  I am interested how Apple will respond to this. In several days, Apple night announce a new device. Will it include an Apple iPad mini? How about Google? Nexus 7 is not looking good when you put it beside a Kindle Fire HD.

How can you not love Amazon?

10 Android Apps for Better Photo Composition

Android Photo Composition

Last week I decided to take my landscape photography seriously. I planned the shot but even if I have the right mindset, it was still a challenge because I found out that I don\’t have the right tools and the correct preparation.

That experience lead me to take composition more seriously. I know this is a cliché — the only rule in photography is that there are no rules but there are composition techniques that we can use to make more artistic photo.  The popular techniques include rule of thirds, golden mean, deep depth of field, shallow depth of field, color, shapes, framing, leading lines and different kind of lines.

You might already know that Nikon released the first Android based camera recently. The apps listed below should could beef-up that camera with DSLR-like features.

If you have a phone camera, point and shoot camera or an entry-level DSLR, you will find these Android apps will be helpful in your composition as well. These apps are not necessary camera apps. Majority of these apps are utility tools to help you understand the technical side of photography. I haven\’t found the iOS equivalent of these apps but I will cover them next time. For now enjoy these Android apps that can help you make better photo composition.

1. Camera FV-5

This is not just a simple camera that puts fancy effects in your photos. It puts DSLR-like manual controls in your fingertips and it\’s probably one of the most advanced camera app in Android.  You can set exposure compensation, ISO, light metering mode, focus mode, white balance and, [shutter] speed mode and program mode. It even have bracketing options and live RGB histograms.

\"Camera

 

2. Sensor Camera

The rule of thirds is probably the most widely use guideline in creating stunning pictures but there are more composition guidelines built around the divine proportions such as golden mean or the golden ratio. Sensor Camera gives you the basic rule of thirds grid as well as golden sections, golden triangle, golden spiral, golden spiral stretched and face geometry.

One of the improvement area on this app is the zoom feature. You can\’t zoom on the current version of Sensor Camera so you have to move closer or farther to you subject if you want to compose your picture using this app.

\"Sensor

\"Sensor

\"Sensor

And one more thing, this app is proudly made in the Philippines.

3. ProCapture Free

You get real-time histogram too but unlike Camera FV-5, you only get 1 histogram with 3 segments to easily figure the midtones, highlights and shadows.  You can overlay 3 x 3 grid or Fibonacci spiral that you can rotate depending on the orientation.

4. Depth of Field Calculator

Depth of field is the most important aspect in selective focusing. If your camera has depth of field (DOF) preview that\’s great, but if you  don\’t have DOF preview it is hard to guess how deep or shallow the depth of field will be until you take your photo.

As part of the  creative process, knowing the depth of field in advance can help you plan the exposure parameters ahead of time so you will not spend your time playing around with different aperture value. Your time is better spent taking great pictures.

Depth of Field Calculator calculates depth of field (DOF) using the specified camera model, the focus length, f-stop and subject distance to give you the near limit, far limit and hyperfocal distance for your camera.

There are several other DOF calculator in this list but this is the easiest to understand. The diagram feature is  the best way to understand how DOF works.

\"Depth

\"Depth

5. DoF Calc

DoF Calc also considers teleconverter in calculating depth of field.

\"DoF

6. DOF Droid

If the diagram of Depth of Field Calculator is not enough, DoF Droid gives you several diagram to compare depth of field against aperture size and focus distance.

\"DOF

\"DOF

\"DOF

7. Exposure Calculator

This app lets you put in the exposure without filter (shutter speed, aperture and ISO) and then the Exposure Value (EV) adjustment which is equal to adding  neutral density (ND) filter.

If you use ND filters, this is the best app you can get in calculating exposure after adding ND filters. Professional landscape photographers would know this by heart but if you are just starting, this app can be a life saver.

\"Exposure

8. Photo Tools

Photo Tools is a collection of photography tools including focal tools, exposure tools, time tools, weather and location tools, color tools and other miscellaneous tools.

If you are learning how to be a good photographer, you can use these collection of tools to understand how your camera works on different conditions.

\"Photo

9. Golden Hour Calculator

This is very helpful if you want to achieve that special sky color when taking your pictures. Golden and Blue hours are calculated by this app using precise algorithms to get the time at any place on Earth at any date.

I wish I have this app when I was shooting seascapes.

\"Golden

10. PHOforPHO

This is a free app for serious photographers – without ads! It includes several tools such as exposure calculator, DoF calculator, timer, distance meter and more.

\"PHOforPHO\"

During design and planning stage of your composition, you can use these apps to setup how you are going to use your camera and photography equipment so that the next time you go on out to take photos you will get better photo composition and a winning shot.
