Simple notification issues... Need all devices to notify when any device drops to 30->20% ("plan to charge soon"). Need all devices to notify when charged to 80->100% ("ready if needed"). Different sounds would not work. Didn't work with all connected and remote devices. Issues upgrading devices... can't remove old devices, app confused between old/new, graphs freeze for hours, even after uninstalling all devices & starting fresh. After wasting a month, didn't bother checking energy rates.

Notifications don't work, which was the point of installing this to begin with since the Galaxy Watch doesn't have any feature to notify you on the galaxy phone when it's almost dead. This app has a setting to notify you when the battery reaches a particular level, but it doesn't actually work making the app useless.

Excellent App. I do have a problem with custom notifications though. It seems that the app default sound always plays rather than my own custom sound. Also i wish that there was separate sound effect options for reaching a specified lower battery and for reaching a specified higher battery. Other than that I'd say this app is perfect.
