Chronos Interval

Chronos is the interval timer built for serious athletes. Design any workout protocol in seconds — HIIT, Tabata, EMOM, AMRAP, circuit training, or custom intervals — then let voice coaching guide you through every round without touching your phone. VOICE-GUIDED WORKOUTS Hear interval names, time cues, and round counts spoken aloud so you can stay focused on your reps, not your screen. GARMIN SYNC Start a Chronos protocol from your Garmin watch and get full workout data synced back automatically. No phone required mid-session. BUILT-IN PROTOCOLS Jump straight in with expert-designed Tabata, AMRAP, and strength circuits — or use the voice input to describe your workout in plain English and get a ready-to-run protocol instantly.

WORKS EVERYWHERE Your protocols and history sync across all your devices so your training goes wherever you do. Built by athletes, for athletes. Download Chronos and train smarter.
