Interval is a fast, focused interval timer for HIIT, Tabata, EMOM and any work/rest training you do.
Build a workout in seconds — set your work, rest and rounds, or start from a ready-made Tabata, HIIT or EMOM preset. Then press start and move. A big, glanceable timer, color-coded phases and clear cues keep you on pace without staring at the screen.
BUILT FOR TRAINING
• Work, rest and rounds you control, with round rests between sets
• Tabata, HIIT and EMOM presets to start from
• A clean preview of the whole workout before you begin
STAY LOCKED IN
• A large timer with color-coded WORK / REST phases
• Two-tier progress: where you are in the round and in the whole workout
• Audio beeps and an optional voice cue on every phase change and the last 3 seconds
• Haptic feedback so you can train heads-down
• Keeps running with the screen locked and in the background
LOCK SCREEN & DYNAMIC ISLAND
• A Live Activity shows the current phase and countdown on the Lock Screen and in the Dynamic Island
YOURS, AND PRIVATE
• No account, no sign-up
• No tracking, no ads, no data collection — everything stays on your device
SIMPLE PRICING
Use Interval free for up to 15 workouts with every feature unlocked. A single one-time purchase — Interval Pro — removes the limit forever and unlocks accent themes. No subscription, ever.

• Rename your workout and pick its icon in a new, dedicated settings screen — tap the workout's name at the top of the builder.
• Background music now keeps playing at full volume during a workout.
• Stopping a workout takes you back to its setup screen instead of all the way to the list.
• Cleaner builder layout — structure and timing reordered for a smoother setup.
