Tutis (App Locker)

Tutis is an application used to lock access to other applications on the device using a numeric lock passcode.

You can set your own lock passcode and unlock time for each app. In order to apply the lock, the following permissions are required and must all be granted:
- Device Administration.
- Accessibility service.

The application has a parametric lock (only available in the Premium version) that allows you to configure the locking of applications based on:
- Time and day of the week.
- Connection to certain Wi-Fi networks.
- Connection to certain Bluetooth devices.

In order to apply the parametric lock via the connection to certain Wi-Fi networks, it is necessary to access the information about the Wi-Fi networks provided by the system. As of Android 9, the app requires location (precise) to be enabled. Additionally, as of Android 10, background location access must also always be allowed.

The app also offers the ability to lock your device by:
- A widget for the home screen.
- An automatic pocket mode detector using proximity and light sensors.

The Premium version gives you the following improvements:
- Removal of ads.
- Parametric lock.
