CallTimeWatcher is a simple and convenient app that automatically monitors your phone calls. It is easy to set up and starts surveillance automatically when you make a call. The surveillance ends simultaneously with the call, making it effortless to use without having to consciously interact with the application.

One of the standout features of CallTimeWatcher is that it allows you to continue talking even if you don't want the call to end automatically. With the button on the screen, you can easily terminate the monitoring if you wish to keep the conversation going.

This app only monitors outgoing calls, so you don't have to worry about it automatically ending incoming calls. During monitoring, a small status icon is displayed on the upper left of the screen, which can be easily minimized if you want to remove the display and focus solely on the call.

Please note that CallTimeWatcher may not work on all phone models, and support is only available in Japanese. Additionally, depending on the model and Android version, the app may not function properly.
