***** Important Note *****

Therefore, it is necessary to disable the energy-saving mode for this app. Please note that further settings may also be necessary depending on the device.

Permissions:
- Phone status: The "Pause timer on incoming calls" feature requires the permission to read the phone status on Android 12 and above. If you want to use this feature, you can grant this permission in the app's settings.

Great app! Very functional and simple to use. Although, I have one suggestion for the developers: can you update the UI into a Material 3 Expressive vibe? I would LOVE and highly appreciate if you can incorporate that into the app. Would definitely give a 5 star for it. Thanks!

It is really easy to set up and doesn't interrupt my music as I am working out!! I can set my workouts up and follow the beeps.
