Apple has a very secure platform for their mobile devices. For us to get access for the user to control their iPhone apps from their Superscreen device you need only 2 simple things.
1. Your iPhone needs to be unlocked
2. Your iOS Superscreen app needs to be open (download from App store once on set-up)
Once both of these are done you are running. Superscreen automatically creates a custom UI on top of the iOS platform so you would then use the Superscreen just as if you were using your phone.
Of the millions of applications there are only a few with limitations, so please see 'iOS App Limitations' FAQ if you have concerns about specific applications.
