Prepare
Build a workout in seconds
Work, rest, rounds — dial in three numbers and you're training. No plans to subscribe to, no library to browse.
Start from a preset
Tabata, HIIT and EMOM come ready to run. Tweak them or use them as-is.
Or shape your own
Sets, rounds, round rest, warm-up and cool-down — every phase is optional and every duration is yours.
Work
Train heads-down
Once you start, the phone can stay on the floor. Every phase change is a beep, a voice cue and a tap on the wrist — the dial is there when you want it, not because you need it.
A dial you can read across the room
Big mono digits and color-coded phases: red means work, teal means rest. One glance mid-burpee is enough.
On your wrist
The workout mirrors live to Apple Watch — same phase, same countdown. Pause from either device.
On the Lock Screen
A Live Activity keeps the countdown in the Dynamic Island and on the Lock Screen. No unlocking between sets.
Rest
Then it gets out of the way
History that stays yours
Every finished workout is logged on the device — streaks and totals included. Nothing is uploaded anywhere.
Private by design
No account, no sign-up, no ads, no tracking, no analytics. Interval doesn't even ask for your name.
In your language
English, German, French, Spanish and Portuguese — the whole app, down to the voice that calls out each phase mid-workout.
Pay once. Own it.
Your first 15 workouts are free with every feature included. One small one-time purchase removes the limit forever and adds accent themes. No subscription — ever.
