-In accordance with Google's policy, you must designate the mandatory call app as the default call app.

This app tells you the total number of calls and talk time from the 1st to today.

You can call directly by pressing the 131 button.

Set a timer and automatically end the call at the specified time.

You can register multiple numbers and call them in turn.

-The timer may not work properly, so please use it only as an auxiliary and check it yourself.

-Since the timer starts from the moment it is pressed, there is a slight error from the actual talk time.
