Interval Workout Timer App

A useful interval workout timer app does more than count down seconds. It should run your full session logic: what to do, when to switch, and what comes next.

Built for structured intervals

• Custom work and rest blocks
• Exercise-specific steps instead of anonymous rounds
• Clear transitions for fast session flow
• Simple repeatability across weeks

For HIIT, conditioning, and mixed routines

Re:Do works for common interval formats while still letting you keep your own naming, ordering, and structure. It is a practical training tool, not a content platform.

Apple Watch companion during intervals

While training, the watch companion keeps the active step visible on your wrist so you can stay in rhythm without checking your phone every set.
