Back in December 2013 we saw the first non-BlackBerry developed app become available in BlackBerry Beta Zone -- MockIt!. It has been available to download for anyone with a Beta Zone account. If you haven't tried it or checked it out yet, MockIt! is an app that allows you to create memes, device mocks for presentation and also photo collages.
There are a lot of the popular meme pictures available but you can also you use any of your own. The app has recently been used a lot to create funny John Chen memes which can be found in the CrackBerry Forums.
You can check out our hands-on video with an earlier version of MockIt! to get a feel for what the app looks like and how to use it.
MockIt! is free to download and is available for all BlackBerry 10 devices running OS 10.2 and above. There are in-app purchases available to purchase sticker packs. There are two additional sticker packs available for $0.99 each, you can also unlock the ability to use your own photos as stickers for $1.99.
If you aren't seeing it yet, just keep checking back. It usually takes up to 24 hours to propagate through the BlackBerry World servers once the developer makes it live.
