Stryke is a new app which allows you to turn videos into .gifs and share them via iMessage or on social networking sites such as Facebook. The official App Store description claims Stryke is "an app to troll your friends," but I'm not exactly sure what that means. However, it does seem like a fun app for fans of Vine and Snapchat who are looking for something new to play with.

Stryke works by allowing you to create animated images from videos on your Photo app. You can use already existing videos on your camera roll or create new ones using the app's Vine-like video tool. The app also allows you to add "witty" captions and music to your creations before you share them.

BlackBerry Limited (NASDAQ: BBRY; TSX: BB) today announced BBM version 2.1 will be rolling out to Android, BlackBerry and iOS devices. As promised, the new update will bring "stickers," the ability to share images in multi-person chats, and the ability to send higher quality photos, videos and presentations.

"Stickers" are just larger emoticons that users can purchase from the BBM Shop to enhance their chats. BlackBerry has also teamed up with the WWE to give away a free WrestleMania 30 sticker pack.

“Stickers are another great example of how we’re making the BBM experience more engaging and fun for our customers,” said David Proulx, Senior Director, BBM at BlackBerry. “Stickers let you personalize your chats and strike the right chord with people around the world who rely on stickers in chats when they connect with colleagues, family, friends, peers and partners.”

iOS 6 added the ability to check how much data you use but it didn't reveal the breakdown of your usage. Luckily Apple remedied the situation with iOS 7 by adding a System Services feature that tells you how much cellular data you are using per app. This is a great tool for helping you pick a data plan, or to see why you tend to go over your data plan each month. Here's how to check your cellular data usage in iOS 7.

First open your Settings app and tap the tab marked "Cellular". It is located right underneath the Bluetooth settings. Scroll down until you see your Call Time log and Cellular Data Usage stats. Just below Current Period Roaming you will see an alphabetical list of all the apps which you allow to use cellular data. If you scroll down further, you will see the Systems Services option.

OMG: TD fans who have their app updates set to automatic, or just don't check them that often, should check them today. Yodo1 Games has released OMG: TD version 1.0.6 featuring 7 brand new ice levels. The update also brings a new boss, Typhon, and two new gods, Dionysus and Athena.

The new levels are not easy and feature new enemies such as the Black Sheep, who can jump over your hero and Hades' ghosts. Other new enemies include Battle Frost Dragons, Snow Bros, Emperor Penguins and Ice Snails. But don't worry, you also have two new inventions, the "mine cart" and "freeze," to help you along the way.

AND that's NOT all!
