Apps installation is pretty similar to the AppStore:

  • Browse app library and tap on app you’d like to install;
  • Tap yellow ‘Install’ button and follow the instructions;
  • This action make take some time, and the app icon appeared on your home screen will be gray for a while. No worries, it’s okay. 
  • If you’re looking for another version of the same app — tap ‘Other versions’ button, review the list of versions available, then tap the desired one and then tap ‘Install’ again.

Please note: Most of applications don’t allow you to install different app versions to the same device, so you might have to remove the previous one before. .
