Describe it instead of building it
No steppers, no forms. Write the workout the way you would say it out loud, in your own language. "Tabata x8". "EMOM 12". "20 min AMRAP". Arc shows you what it understood before anything starts.
Interval & HIIT timer
Type "3 rounds of 40 on 20 off, then 2 min cooldown" and the whole session appears as one ring under the field, with every work and rest interval a visible arc. Tap it to fine-tune, or press Start.
The timer is free forever. Arc Premium is one payment of $9.99, not a subscription, nothing to cancel.
Most interval timers make you build the workout twice: once in your head, once in a form full of steppers. Arc takes the sentence.

Point the camera at the board, at a coach's post, at a screenshot. The text is read on your phone and turned into intervals. The photo is never saved and never leaves the device.
Arc PremiumOn iPhone the timer lives on your Lock Screen and in the Dynamic Island: countdown, round, phase, pause and skip. On Android it is a home-screen widget and a notification you can drive. Put the phone in your pocket and keep moving.
Work floods the screen red, rest floods it mint, and the number is enormous. You can read it from two metres away, face down on a mat, without your glasses.
Intervals, Tabata, EMOM, AMRAP and fully custom sequences: any number of intervals, rounds and sets, with prep, set rest and cooldown. Beep, voice and haptic cues, playing over your music instead of stopping it.

Not just the interval you are in, but where you are in the session.






Nothing inside a running workout is ever locked. Arc monetises the things you reach for after the first week, not the Start button.
