This page is a metronome.
This is Groove Lab's own engine running in your browser, with the app's own sounds. Press play. Tap a pad to accent or mute it. Split any beat into subdivisions, change the meter, switch the kit, pick a theme.
Your whole piece, in one click track.
Real music changes meter. Repeats, tempo curves and count-ins live in the same builder, so you practice the piece instead of fighting the metronome.
A drum machine that knows strong beats from weak.
Eight sound profiles, from a clean click to funk, disco and EDM kits. The drums understand grouping: set 2+2+3 and the kit plays 2+2+3, with the weight where a drummer would put it. Tap a name to hear it.
Come up to speed.
The tempo trainer raises the click a few beats per minute every few measures while you play, so a passage climbs to performance tempo on its own. Gap training mutes the click for a few bars at a time and lets you hear whether your time holds through the silence.
Set it, then forget your phone exists.
Groove Lab keeps clicking with the screen locked or your sheet music app in front. Play, pause and change tempo from your headphones or the lock screen. No ads, no account, and it never needs the internet.

Built for my own practice.
I made Groove Lab after getting frustrated with other metronomes: building a mixed-meter practice track was so tedious it rarely felt worth doing. I wanted one simple enough to reach for even in a short passage with a difficult rhythm, and quick enough to set up the subdivision I want a student to hear, live, in a lesson.
