RunSplit

A color-coded interval coach for iPhone and Apple Watch.

Green WORK, red REST. RunSplit coaches HIIT, tempo, and run-walk sessions by time or distance with an on-device Apple Intelligence voice coach, an Apple Music mixer that swaps playlists between phases, live splits on a MapKit route, a shoe mileage tracker, an Apple Health Conditions dashboard, calorie tracking, Strava sync, and cinematic 9:16 flyover videos of every run — all saved natively to Apple Health, with no account and no subscription.
