RunSplit
A color-coded interval coach for iPhone and Apple Watch.
Green means work, red means rest. RunSplit coaches HIIT, tempo, and run-walk sessions by time or distance, with a voice coach that talks you through each phase and music that changes with it. Watch your splits on a live map, track the miles on your shoes, keep an eye on calories and health trends, sync every run to Strava, and share a cinematic flyover video when you're done. Everything is saved to Apple Health — no account, no subscription.
