I have this paid version and have been using it for a while. A few months ago something happened where the timer won't sound the alarm when I don't have it open and it has gotten overall very buggy; it could be because the latest Android version. That takes a lot of the use our of it. I have used the app for a while and I do like it. The creator might have stopped working on it. It's too bad, but I think I got my money's worth with all the times I used it.

Great app, only had 1 problem, accidentally started previewing the alarm noise somehow volume shot up to full and application closed with no display or notification area info, couldn't see the cause to turn it off and vol control wouldnt go to 0, had to reboot. Only found out it was ultrachron when something similar happened months later but that time I recognised the display that was showing for a second as I'd picked up the phone. Pls add notification 'tap to silence' as others have.

This used to be great, but it seems to have been abandoned. It hasn't been updated in two years and now crashes every time I leave the app because it doesn't have the necessary permissions for Android 14 timer scheduling. Unable to pause activity: java.lang.SecurityException: Caller spinninghead.talkingstopwatch needs to hold android.permission.SCHEDULE_EXACT_ALARM or android.permission.USE_EXACT_ALARM to set exact alarm
