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.

I love this app except for one problem. The start button seems to have a keybounce problem. I've had several instances where the timer stopped just a fraction of a second after I started it, but I didn't notice it had stopped. It needs to buffer the button input so it doesn't respond to a change only a few milliseconds later. Otherwise I would give it 5 stars. Using it on an HTC U11 w/ Android 9.

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.
