User Reviews

Overall mixed sentiment: the app is praised for its simple, useful charging alerts and works for some users when kept in the foreground. The major recurring drawbacks are iOS background restrictions that prevent reliable alarms when the phone is locked, plus occasional failures after updates. A few users note a workaround via iOS Shortcuts/Automation, but reliability remains inconsistent.

Pros

Generally positive reception; described as a simple, useful battery charging alert app.
Works when kept in the foreground, for users who keep the app active on screen.
Supports iOS Shortcuts/Automation as a workaround to monitor charge and trigger alerts.

Cons

Does not run in the background; requires the app to stay on screen, limiting multitasking and causing alarms to fail when the phone is locked.
Alarm is not reliably triggered at the set percentage, especially when the device is locked or the app is not active.
Recent iOS updates/restrictions have broken or degraded background functionality for some users.
The set alarm level can be forgotten or reset between uses.

Recent reviews

The battery is yet 100% when the alarm goes off. It’s only 85%.

I’ve had a problem with another battery alarm app that can run in the background, but every few days it started ignoring the 80% limit and charged the battery fully every time. I deleted and reinstalled it twice, so three times and you’re out. This one works fine so far, though I’m unclear why it has to run in the foreground. I’m disappointed however that the pro edition isn’t available in my neck of the woods. Does that mean no one in the US can get the extra alarms etc? I hope that will change. I’ll write the dev and see what gives.
