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.

On my new Samsung S20 Plus, the Ultrachron is now unusable, unless the app is active on the unlocked display. I reinstalled the app, manually added Storage permissions, but Ultrachron still only works when it is active on the display. Developer: I have an app in the Play Store that periodically tests the internet, using a persistent Service, and notification channels with repeating alarms. It is compatible with Android 4.3, through Android 10. I would be willing to share some code Snippets.
