TempoLock

TempoLock — Know your tempo. Every song, every set.

TempoLock tracks your tempo in real time while you play. Watch it on a live tempograph in 1, 5, 20, or 60 minute windows.

Real-time tempo tracking
TempoLock listens as you play and locks onto your tempo live — no tapping, no manual BPM entry. It follows a steady groove and keeps up when the tempo moves mid-song.

Tempograph and tempo log
Watch your tempo curve live in 1- and 5-minute windows, then step back to the 20- and 60-minute views to see the songs in your set as tempo lines. Steady songs are saved to your tempo log with their average tempo and how steady they were.

Setlists with tempos
For each band or artist, build a song list with a tempo for every song. Tap a song to start the metronome click at its tempo for a precise count-off, then step through your set with the next and previous buttons during the gig. Export your setlist as a PDF.

Stage Mode
A giant tempo readout and beat flash you can read from arm's length.

Built with real bands
Refined with real bands in real live sets — not just a metronome built in a vacuum.

Private by design
Audio is analyzed on your device in real time. Nothing is recorded, saved, or sent anywhere.

Whether you're chasing a tighter pocket in rehearsal or want a record of how steady a set really was, TempoLock gives you the data.
