Cadence: Tempo & BPM

Build class sets by tempo, lock a whole playlist to one BPM, and slow any song to drill a section without changing the pitch.

Cadence is a music player built around one thing most players ignore: tempo.

Other speed-changer apps only let you nudge a song by a vague percentage. Cadence works in real beats per minute. Set a track to an exact BPM and see at a glance which songs already sit at the same speed — so you can line up a whole set at the pace you want. For anyone who dances, teaches, or practices to music, that's a different kind of control.

WHAT YOU CAN DO

• Work in real BPM, not percentages. Every track carries its actual tempo, so "128 BPM" tells you something useful and you can match songs by speed.

• Set the tempo your way. Tap along with the beat to set a song's original BPM, or let Cadence detect it automatically.

• Change speed on your own tracks with the pitch kept natural. Import local audio and slow it down to drill a tough passage, then bring it back up to tempo as you improve — no chipmunk vocals.

• Build playlists and sets. Group tracks for a class, a practice session, or a social, and sort by tempo to sequence songs by speed.

• Share a set. Send a playlist to another dancer and their Cadence imports it with every tempo — original and preferred — intact.

• Bring your own music. Add songs from your Apple Music library (an Apple Music subscription is required to play catalog tracks), or import audio files straight from your device.

WHO IT'S FOR

Teachers who need a song at exactly the right pace for a class. Dancers who want to practice below tempo before taking it up to speed. Anyone who's ever wondered whether two songs are actually danceable at the same rhythm.

Cadence is free to use.
