I used this app for years until today. I recommended it to my friends, and it was a great app. Low system resource impact, tolerable ads, and perfect you can't even open the app without having to watch a 30 second ad that takes another 10 seconds afterwards to give you an escape option. Same every time you change a setting. Im uninstalling. There are other apps that do this....good job devs. You took something great and ruined it.

Sorry for the bad experience with the app. The new version (v4.2.9) of the app is more stable and supports Android 10, the update is available. Can you check now please. It should work perfectly. If you think we have made the app better for you, please do rate us 5 stars.

I have tried several battery alarms and found issues with most of them. They have been unreliable and not alarming a 100% of the time, No easy way to remind user to turn on or excessively draining the battery. Battery 100% alarm Resolves all those issues I have a perfect track record of alarm sounding, Battery does not seem to drain excessively And there is a Widget feature That allows you to put a Readily seen Icon on the home screen to remind you to turn on . All in all an excellent app.
