The My Mobile App Directory is the starting point for all My Mobile App customers.
The Directory exists as an app in both the Apple App Store and Google Play. It is where you can preview your app before upgrading to a paid plan; or can use it as your app in its own right.
All you need to do is install the Directory, 'favourite' your app, and then use it as you would a stand-alone app. You can instruct your customers to do the same. Apps added to your 'favourites' will receive Push Notifications.
