About Interval Run
Interval Run is an interval timer and workout builder for iPhone and Apple Watch.
Pick a workout. Build a workout. Run it.
The app brings run/walk timers, structured steps, voice cues, and an Apple Watch workout into one flow. Choose from 30 ready-made interval workouts or build a custom sequence with the advanced editor.
From interval timer to workout companion.
Interval Run first appeared on the App Store in January 2015. The August 2026 version 3.0 release added a redesigned workout experience with Apple Watch support, Apple Health tracking, workout history, and more ways to build and follow intervals. The App Store listing records the release history.
Designed to keep your workout yours.
There is no account, advertising, tracking SDK, or server that stores your workouts. With your permission, completed sessions can be saved to Apple Health.
