BUILD AND REPEAT YOUR WORKOUTS Create unlimited custom workouts — define exercises, reps, distance, time, or calorie targets. Mix and match into circuits, complexes, and benchmark WODs. Save your favorites, then load them again to test yourself against your own history. Automatic scoring by workout type: rounds, time, or total reps.

TRACK WHAT ACTUALLY MATTERS Workout history with week, month, and year views. Visual charts of frequency and consistency. Personal bests tracked automatically per workout. Streaks with Core Training Score (CTS) multipliers — 100-day streaks unlock 1.5x, and Rest Tokens auto-recover a missed day awarded once or twice a week. Up to you.

LIVE HEART RATE, NO GUESSING Connect a Polar H9, H10, or Verity Sense for real-time BPM and zone tracking mid-workout. Watch your zone shift color as intensity climbs, then review your full zone breakdown after you finish.

SMART CALORIE TRACKING MET-based calorie calculation using your weight, workout duration, and effort level (Easy to Very Tough) — not a flat estimate. Every calorie feeds into your CTS score.

BUILT TO KEEP UP Runs reliably in the background, even with your screen locked. Auto-pause and resume on lock. Precision timing via RunLoop that never drifts. Syncs to Apple Health on iOS 26+, alongside your steps, rings, and daily activity.

PERFECT FOR CrossFit athletes and box owners HYROX competitors and coaches Personal trainers running client sessions HIIT and functional fitness training Strength and interval training Anyone who's outgrown a basic gym clock
