*** ROOTED DEVICES ONLY ***
You can setup a time of the day and the app will automatically reboot android on a daily basis.
Or you can configure a text that when received via SMS to the device will make it reboot.
Alternatively you can set a remote URL and ping interval and if the resouce returns the configured text the device will reboot.
This can be used as a watchdog when android is used as a telemetry device such as in the https://openweatherstation.com project for which this app was originally designed.
Use it at your own risk.
