What this does

A supervised iPhone can be told to run one app and nothing else. Turn it on and it is a camera. There is no home screen to get back to, and no way out without the setup being undone.

Before you start

  • The phone is erased in the process. Do not use one with anything on it you want.
  • You need a Mac, or a device-management tool on Windows.
  • Give yourself an hour the first time.

The shape of it

  1. Erase the iPhone.
  2. Supervise it while setting it up, using Apple Configurator on a Mac.
  3. Install Mupi and sign in to iCloud so photos can back up.
  4. Set Mupi as the single app the device is allowed to run.

Worth knowing

  • This is Apple's supervision, not something Mupi controls. Mupi is simply the app you point it at.
  • A dedicated camera does not use less battery by itself. Mupi stops the camera when it is idle, which is what actually helps.
  • If this sounds like more than you want, use Guided Access instead. It is two taps and undoes itself.
