How we work
A few things to know.
You can use the tools without signing in. Here’s how we handle the rest.
Free to use
All the tools and music references here are free. The apps are free too.
No account needed
Open a tool or reference page and use it. You don’t need to sign in, and the tools stay free when you do.
Audio stays on your device
Tuner processes sound on your phone without uploading it. In Pitch, recordings stay on your device unless you choose to export them.
Checked before publishing
We use AI to help with drafts. A person reads the written pages before they go up. The music references are calculated from music theory and tested on every build.
