LET THE MUSIC SET THE TEMPO You already own the music. Run2Beat sets the tempo. Choose the cadence you want to hold — whether running, power walking, or cycling. The app picks tracks from your personal library and plays them at exactly that tempo. While streaming services offer rough estimates, Run2Beat locks in a steady beat so your steps and pedals fall into rhythm. Sync to Apple Watch and leave your phone at home. Same lists, same tempo — just your watch and your headphones. WHY RUN2BEAT • Free and private. No subscription, no ads, no account required. Works completely offline. BPM analysis runs on-device, meaning your audio files never leave your phone. • A full player on your wrist. Sync BPM lists, standard playlists, and Starred tracks. The home screen lets you replay your last list and view today’s Move goal progress, plus you get two watch-face complications. Equalizer profiles are configured on iPhone, and you choose which one plays from the watch. On Series 7 and later, including Ultra, you can manage Crossfade and Beat matching right on the watch. Older models play songs consecutively. • Cohesive sound. Loudness normalization (LUFS) ensures tracks match at consistent volume. A 10-band equalizer with named presets carries over to the watch. Crossfade can wait for the beat so the next song drops in seamlessly — on iPhone and newer Apple Watch models. • Your rules. Add an optional warm-up at a gentler tempo. Set strict pitch limits so vocals always sound natural. Choose whether your feet land on every beat, take two steps per beat, or take one step every other beat. • Standard playlists post-workout. Share lists easily via AirDrop. In the car, seamlessly pick up where you left off with CarPlay. THE BEST PART The music is yours. No streaming subscription required, no cellular connection needed, and no favorite tracks disappearing when licensing deals end. You provide the files — songs you own or receive via AirDrop. We adjust them to your target tempo so the music drives your pace, whether on iPhone or on Apple Watch with your phone left behind. Supports MP3, M4A, and WAV. Shazam can fill in missing tags. Optional HE-AAC conversion saves storage. Learn much more — including how to source tracks — at Run2Beat.com.
