Strumhold is a web app you can install straight from the browser. Drills, scoring, and your history all work with no connection.
The hard part of guitar is the change.
Strumhold drills the switch between two chords. Strum along to a steady beat, and it listens through your microphone and scores every change — so you can watch your switches get cleaner, drill by drill.

How a drill works
-
Pick a pair
Two chords you're learning — say, E minor and A minor.
-
Strum with the beat
A steady count keeps you honest. Switch chords on cue and keep strumming.
-
Every change gets scored
Your microphone picks up each strum, and the app scores the change — did you land the new chord, in time?
Built to stay out of your way
Your practice stays yours
Everything is saved on your device. Your microphone audio is processed on the spot to score your strums — it is never uploaded.
Sized for beginners
A small set of open chords, drilled two at a time — the changes that trip you up in real songs, practiced until they don't.
Free to practice. Sync when you want it.
Every drill above is free, forever, no account. One optional subscription — $0.99/month or $9.99/year — backs up your practice and keeps it in sync across your devices.
