Auto-unlock and auto-open when movement is detected.
Configures your Android device to automatically unlock and optionally open an application when it detects your presence using the camera and ambient light sensors.
While initially designed for an Android-based home security system, it's also perfect for Home Assistant, Calendars, and Public Transit schedules. No more tapping the screen—just walk up and it's ready. This app is similar in concept to Yakk, but I didn't know it existed when I started hacking on this. In comparison, TOE is open-source, with support for more sensors and different customization options. TOE does not record video or store data other than your configuration data. TOE does not require any network access.

On first launch, the app will request the following permissions:

- Battery optimization exemption - For reliable background operation
These permissions are essential for the app to function properly.
