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."
