Description by Curious Labs Written by the developer, not by AppBrain. Click to read.
It's the app you reach for mid-practice and set down thirty seconds later, having gotten exactly what you came for. Clean, quiet, and quick to navigate, built for piano and stringed instruments alike.
What's inside:
Chord finder for piano, guitar, and other stringed instruments
Chord identifier: play a chord and it names it, and shows which keys it lives in
Key finder: listens to a song, tells you its key, and sets the whole app to that key
Chord families: the main chords in any key, at a glance
Scales in every key, clear on both the fretboard and the keyboard
An accurate tuner
A clean Tools section that keeps each of these a tap away
What's not inside:
No subscriptions
No ads
No sign-up
Just a beautifully simple tool that respects your time and your ears.
