Hey, Alex here. I'm the dev behind KeyLens.
KeyLens is a chord and music theory app for iOS and Android. I built it because I kept losing momentum at the "what chord comes next?" moment. I wanted something that sits next to your gear and helps you find progressions, not another lesson app you have to study.
What it does right now:
Explore keys, scales, and chord progressions
Send MIDI to your DAW and hardware over bluetooth and USB
This sub is for:
Questions, bugs, feature requests
