Run in rhythm with YOUR own music. BPM Runner automatically analyzes your Apple Music library and sorts every track by BPM (beats per minute). No pre-made playlists, no streaming catalog : just the music you already love, filtered by your running cadence. HOW IT WORKS 1. BPM Runner analyzes the real tempo of each track in your library, right on your iPhone. 2. Pick your zone : Walk, Jog, Run, Sprint. 3. Hit play and only the songs at the right cadence go into your queue. FOUR PACE ZONES Walk (60 to 99 BPM) : warm-up Jog (100 to 129 BPM) : endurance Run (130 to 159 BPM) : fast tempo Sprint (160 to 200 BPM) : maximum effort Matching your music's tempo to your running cadence helps you hold a steady pace, lowers perceived effort, and makes longer runs feel easier.
