Powernotch: Battery Monitor
Every battery.
One glance.
Your Mac, keyboard, mouse and AirPods in one side panel that stays out of your way until you need it.
A panel on the side, not in your way.
A black panel with rounded corners at the left or right edge of any screen. It works on every Mac, with or without a notch.
Hides until you need it
A thin tab at the edge of the screen. Touch it with your mouse and the panel slides out. After a delay you choose, from 0.2 to 3 seconds, it slides back. Or keep it open all the time.
One ring per battery
Each device gets a ring with its icon and percentage. Green above 50%, yellow down to 50%, red at 20% or lower. A bolt appears while charging.
Hover for the details Pro
Move over a ring for a card with the name, percentage, charging status, remaining time for your Mac and when the value was last read. AirPods show left, right and case separately.
