Mute your part. Keep the band.
Upload a song and it splits into vocals, drums, bass, and everything else. Turn down your part, slow it down, and play along. Then log the session and watch the hours add up.
FREE · IPHONE · NO ACCOUNT NEEDED
Everything a session needs. Nothing it doesn't.
Any part of the song, on its own.
Upload audio you own and the app separates it into four stems. Mix them however you like, loop the passage that trips you up, and slow it down without changing the pitch.

Steady tempo, out of your way.
Tap in a tempo or nudge it one beat per minute at a time, with an accent on the one, any time signature, and five sounds to cut through your instrument.

Tap once. It's already counting.
A full-screen timer that opens running and keeps the screen awake. Lock your phone or switch apps and the clock stays right. End the session and it drops into your log with the time and date filled in.

Hear what you actually played.
Record an audio take mid-session. It's saved with that session, so you can put last month next to today and hear the difference.

Watch the hours stack up.
Total time on every song, minutes per week, a Weekly Goal, and a streak that's easy to keep. Move songs from Learning to Practicing to Polished as they come together.

The journal is free. Stems are extra.
Everything you need to practice and track it costs nothing. Subscribe when you want to split songs into parts.
