Battery Life Monitor and Alarm

Full-charge and threshold alerts

The charge alarm sounds when the battery reaches the threshold you set, which the listing describes as a full-charge alert. You choose the level yourself, so the alarm can fire before the battery is completely full.

A separate low battery warning uses its own sound. The listing says each stage of the battery's charge can have its own notification, so you can tell the alerts apart by ear.

Charger connect and disconnect sounds

A charger notification sound plays when the device starts charging and when it stops. The listing says this helps you notice an unplugged cable or a charger that is not delivering power.

The sound used for these events is one of the notification sounds you can select in the settings.

Choosing sounds and thresholds

The settings let you choose the sound for each charge stage and set the threshold for the charge alarm. The listing describes these as adjustable options for tailoring alerts to your own routine.

The listing also describes the interface as easy to use for managing battery status. It does not give further detail on how the screens are laid out.

Using the alerts on a Wear OS watch

The listing states that the app supports Wear OS devices, so the same battery alerts can run on a compatible smartwatch. The listing does not say which watch features are included on that platform.
