You head out for a run, and halfway through the first kilometer your pace drifts from the playlist you started with. Bematist, from developer pakeha-by, reads your steps per minute from the phone's motion sensors and swaps in tracks whose tempo fits. It plays only files already stored on your device. TopDown APK hosts the unmodified APK for version 1.1.0.
First steps after you install the cadence player
Bematist needs Android 13 or newer, and the download is 5.1 MB. Once installed, point it at your music files and let it scan the library. Each track is analysed for tempo on the device itself, so the first scan is the only setup step that matters.
After the scan, matching works fully offline. The app asks for no account and uses no network or server, so there is nothing to sign in to before your first run.
Tempo matching, manual BPM dial and triage mode
The core feature is real-time matching of your local music's BPM to your running cadence. The app switches tracks automatically as your pace changes. Half-tempo and double-tempo tracks count as matches, so a 172 BPM track suits an 86 steps-per-minute pace.
When the step counter cannot be trusted, for example on a treadmill or with the phone in a bag, you can set the BPM range by hand. You drag it around a dial and pinch to widen or narrow it.
Triage mode lets you rate tracks mid-run as skip, keep or like, using an on-screen gesture or an earbud button. Afterward the app sorts them into playlists. Every run is logged with its cadence and track-matching detail, and you can browse it in session history.
Who should pick Spotify or Fossify Music Player instead
Bematist plays only music files already on your phone. If you want streaming or a catalogue to discover new songs, the alternatives listed for it, such as YouTube Music or Spotify, fit better. Bematist has no streaming or store feature.
If you want a plain local player with no running logic, Fossify Music Player or Apollo are closer to that. Bematist makes sense when running pace is the reason you open a music app.
What's new in 1.1.0
Version 1.1.0 was updated on October 31, 2026, after the first release on October 8, 2026.
