01 / FIND IT
No shouting across the house.
Just your iPhone and a wired charger.
Connect your iPhone to the outlet with a wired charger. Open BreakerMap, preview your alert, and start a test.
Switch breakers one at a time. When your iPhone loses charging power, BreakerMap sounds an alert.
Restore power, choose the breaker, and save the outlet to your map. Add a room, a note, or a photo if you like.
Keep the app open and your iPhone unlocked during a test. Read the setup guide
02 / MAP IT
Turn a row of switches into a map of your home. Find a circuit by room, see what it powers, and leave the guesswork behind.
