What is the HockeyApp
Our app is still in development and we have not released it yet. We do not want our backers, that's you, to wait until we release the app, so we made the beta available. The beta is not the finished app, but more a taste for you to play with and see the developments and features/ languages we are adding one by one. Since the app is not launched, we can not put it in the stores where you would normally download the apps from. This is why we use HockeyApp. HockeyApp allows us to get the beta to you whether you are an iPhone or an Android user. Later when the app is released, you will simply be able to download it from the stores as per usual.
