Ardo — AI Interval Timer

Ardo is the interval timer with an AI coach built in. Tell it your goal, your gear and how long you have — and it builds a custom interval workout, names every exercise, and drops it straight into the timer.

YOUR AI COACH Chat with Ardo like a real coach: "20-minute fat-burning HIIT, no equipment" or "kettlebell strength, 15 minutes." It designs the intervals, picks the exercises and shows each move on screen as you go. Save it to your workouts or start right away.

140+ READY WORKOUTS Tabata, HIIT, EMOM, AMRAP, For Time, CrossFit benchmarks (Fran, Cindy, Murph), Hyrox, circuits, running and boxing — a big ring keeps you on pace with a 3-2-1 countdown, work/rest phases and a clear "next up" preview.

BUILD YOUR OWN Lego-block editor with nested round groups; fork any preset, the original stays untouched.
