RunSplit
Smart interval coaching that runs entirely on your device.
RunSplit is a run/walk interval coach for iPhone and Apple Watch built around a clean green work / red rest loop. Coach through HIIT, tempo, and run-walk sessions by time or distance, with on-device AI voice cues, an Apple Music mixer that swaps playlists between WORK and REST phases, live splits on a MapKit route, a shoe mileage tracker, and Strava-style share cards all saved natively to Apple Health.
