I built DrumLock so you spend the whole practice session practicing, not switching between a metronome app, a rudiment chart, a song speed changer and a method book.

Build one routine from timed segments: a rudiment with its notation, a song section trimmed and looped at the speed you set, a photo of the page you are working from, the metronome under all of it. Press start and play straight through. The app moves to the next segment on its own and logs the session when you stop.

Four of the five tools are free. The fifth, playing your songs slowed down and looped, is a one time $4.99 unlock. No ads. No accounts. Works completely offline.

WHY DRUMLOCK
━━━━━━━━━━━━━━━━

Most metronome apps just click. DrumLock runs the whole session, so you never leave the kit to switch apps, flip pages, or find the loop point.

Learning a song? Import the recording, trim to the chorus, loop it at 75% until your hands know it. Building speed? Set the trainer and let it climb. Working through a method book? Photograph the page, drop it in a segment, and play to it.

Free to download. Try it in your next practice session.
