A new workout every day, built around the time you have and the gear you own. No program to follow, no spreadsheet to fill in — open it, hit generate, train. BUILT AROUND YOUR GYM Tell it what you've got once — barbell, rig, rower, kettlebells, or nothing at all — and every workout it writes is one you can actually do. Training in a hotel gym this week? Change it in two taps. FOUR TIMERS THAT KNOW THE WORKOUT AMRAP, For Time, EMOM and Tabata, each wired to the workout on screen. Round counting, spoken cues that call out halfway and the last ten seconds, and a Live Activity that keeps the clock on your Lock Screen while your phone's in your pocket. YOUR MUSIC, WITHOUT LEAVING THE WORKOUT Pick a playlist from your library or search Apple Music, then play, skip and shuffle from the home screen or the timer itself. It drives the same player as the Apple Music app, so your Lock Screen and Control Center stay in step. (Apple Music subscription required.) EVERY BENCHMARK, WITH YOUR HISTORY The Girls and the Hero WODs, ready to run on the right clock. Every attempt is saved with its date and whether you went Rx— so the next time Helen comes up, you know exactly what to beat. LOG LIFTS, NOT JUST METCONS Sets, reps and load, with tap-to-complete and a rest timer built in. Personal records at 1, 3, 5 and 10 reps are detected automatically — you never have to remember to record one. Row, run, ski and bike results log alongside them. Pounds or kilos, miles or kilometers — your call. CONVERT ANYTHING 400m run = 500m row = 875m bike. Swap machines or movements with easy equivalent distances and muscle stimuli, no guessing. Plus plate loading and percentage work — ask for 80% of your max and see the exact plates for each side. SKIP WHAT YOU CAN'T DO Switch movements off — for skill, preference or injury — and they never turn up in a generated workout again. YOUR DATA, BACKED UP Sign in with Apple or add an email, and your logs and PRs survive a lost or replaced phone. Move your whole history in and out as CSV whenever you want. No account needed to start training. NO NOISE No ads. No feed. No streak guilt. A dark interface built to be read at arm's length, mid-workout. — METCONRX PRO A 14-day free trial starts the first time you open the app. Full access, no card required.
