コジ時計 is a simple yet feature-rich clock app for Android that aims to provide users with a variety of functions.

[機能１] The app can be used as a time signal by simulating a radio clock on your smartphone. It displays both analog and digital clocks, and when the "Sound ON" option is enabled, it emits a sound every second, giving you the feeling of making a call to the time service. Additionally, it plays a time signal from 57 seconds to 0 seconds, making it a useful tool for setting the time on mechanical or non-radio-controlled quartz clocks.

[機能２] コジ時計 can also be used as a kitchen timer (countdown timer). Once you start the timer, it continues to count down even if you close the app, and it notifies you when the specified time has elapsed. It runs in the background but will be dismissed once the specified time has passed. This makes it convenient for various tasks, such as cooking instant noodles or any other countdown activities.

[機能３] Furthermore, コジ時計 can be utilized as a world clock. You can register different regions from around the world and view their respective local times in a comprehensive list.

[機能４] Lastly, コジ時計 can function as a stopwatch. It has a user-friendly interface with two buttons for starting and stopping the stopwatch, and you can take up to three laps. To conserve battery life and prevent performance issues, the stopwatch intentionally does not run in the background, so it stops when you close the app.
