STRIMMA: THE TRAINING TIMER BUILT FOR SERIOUS ATHLETES
Not another basic stopwatch. Strimma is a workout timer, WOD library, and training log built for people who take their training seriously — CrossFit athletes, HYROX competitors, coaches, and personal trainers who need more than a countdown clock.
NEW IN 3.0
Complete redesign — cleaner, faster, built around how you actually train
Lap Timer now tracks meter and calorie splits on every lap, not just time
Save any workout and re-run the exact same challenge to chart real progress over time
Settings and Profile split into dedicated sections for faster navigation
SEVEN TIMER MODES FOR EVERY WORKOUT STYLE
Simple Timer — quick burns or all-day stopwatches
Workout of the Day - WOD
Workout Library - benchmarks and more
EMOM (Every Minute On the Minute) — hit your reps on the clock
AMRAP (As Many Rounds As Possible) — maximum volume, fixed time
Tabata — customizable work/rest intervals, 1–300 seconds each
For Time — race the clock with live progress
Lap Timer — track splits, meters, and calories between efforts
HYROX — the only timer built for the 8-station functional fitness race, with preset sessions (Full, Sprint, Fast, Mini, Reverse Sim, Remixed) plus unlimited custom builds
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
