Battery empty / charging reminders for wearable

Should let you know battery life and when to charge.

Changed the title from "App" to "App: battery empty / charging reminders for wearable"

Great idea!

The pulse battery level should be indicated on the app.

Hey, it's already indicated in the little circular bubble that is visible on the Player/Metronome screen and in Settings/Device settings. I believe this suggestion thread is about an automatic alert/push notifications that pops up when you run low :)
