GrooveRun

GrooveRun matches the tempo of your music to your running cadence. CHANGE THE SPEED OF ANY SONG Play songs from your device's Music library, or files you import. The pitch stays where it was — only the tempo moves. The app also ships with 60 tracks prepared for running. (The bundled tracks are AI-generated, and are labeled as such in the app.) FOUR SCENES, ONE TAP Set a target cadence for warm-up, hard, jog and cool-down. Switch between them while you run, and the music follows. INTERVAL TRAINING Tabata, Norwegian 4x4, 30/30 and more are built in. Step length, target cadence and the track that plays there can all be edited on the screen you start from — and each phase plays at its own tempo. BEAT GUIDE Lay a metronome or drum on top of the beat. It gets louder the further you drift, so you can correct by ear alone. The Lock Screen shows your measured cadence and whether you are fast or slow, with a button to turn the beat on and off. GPS ROUTE Your route is recorded with GPS, even with the screen off, until you finish the run. Where GPS is weak, steps fill in the distance. History shows the route colored by how well you stayed on the beat. Routes are stored only on your iPhone and are never uploaded. SHARE CARDS Right after a run, take a photo or a 5-second video and turn it into a share card: distance, time, pace, cadence, sync and your route colored by sync, with stamps and text. Share it to X, Instagram, TikTok, Threads and more. You can hide the area around your start and finish to keep places like your home private. YOUR TRAINING PARTNER A voice keeps you going while you run. There are 100 missions to work through; finishing them earns badges and unlocks new coaching styles — including a Spartan mode that does not go easy on you. APPLE HEALTH Time, distance, cadence and route stay in the app, and runs can be written to Health as workouts. ---- FREE Bundled tracks, tempo sync, scene switching, intervals, the beat guide, GPS routes, share cards, missions and Health export are all free. Importing your own songs is limited to 5 tracks. GROOVERUN PREMIUM (one-time purchase) - Import as many of your own songs as you like - No ads A single payment, not a subscription. NOTES - Songs from a streaming subscription (Apple Music, YouTube Music, Amazon Music, Spotify and the like) are protected and cannot be imported. The one-time purchase does not change that. What you can import is music you own: ripped from CD, bought outright, or your own audio files. - Cadence measurement needs Motion & Fitness permission. - Route recording needs location access (While Using the App). Without it, distance is measured from your steps.
