Point it at your music. Tempo is detected on your device by a neural beat tracker — nothing is uploaded, ever.
Tell it your cadence — say, 175 steps or 90 pedal strokes per minute.
Get an ordered playlist that locks to your cadence, with beat-matched transitions between songs.
Works with the files you already own.
A 90 BPM groove fits a 180 SPM run. BPM Companion knows, and labels it.
All analysis happens on your device. No account, no upload.
Songs hand off on the downbeat, like a DJ.
The same Rust core on both platforms — identical results.
Building a fitness app? The tempo engine is available as an SDK.
