How it works

Analyze<br>Point it at your music. Tempo is detected on your device by a neural beat tracker — nothing is uploaded, ever.

Pick your cadence<br>Tell it your cadence — say, 175 steps or 90 pedal strokes per minute.

Go<br>Get an ordered playlist that locks to your cadence, with beat-matched transitions between songs.

Built around the beat

Your music, not a rented catalog<br>Works with the files you already own.

Half- and double-time smart<br>A 90 BPM groove fits a 180 SPM run. BPM Companion knows, and labels it.

180 SPM ← 180 BPM · 90 BPM

Private by design<br>All analysis happens on your device. No account, no upload.

Beat-matched transitions<br>Songs hand off on the downbeat, like a DJ.

iOS & Android, one engine<br>The same Rust core on both platforms — identical results.

Licensable engine<br>Building a fitness app? The tempo engine is available as an SDK.
