Mighty is the gym log for people who lift. Every set, rep and weight in one place, with records, progress and muscle recovery you can read at a glance. Logging is free, and there are no ads. YOUR CAMERA COUNTS THE REPS Prop your phone up and Form Coach counts your reps out loud on bench press, squats, deadlifts, curls, pull-ups, rows, lunges and more. It checks squat depth, press lockout and push-up hips, reviews every set, and lets you fix the count before it is saved. Free for everyone. AN AI PLAN THAT STARTS FROM YOUR NUMBERS Answer one question per page and get a plan for the weeks ahead: starting weights taken from your own log, warm-up sets for your main lifts, and loads rounded to the plates and dumbbells your gym really has. The Coach tab opens on today's session, and the So far tab shows the sessions you've done, the records you've set and how your main lifts have grown. A GYM LOG THAT KEEPS UP • Sets, reps, weight and RPE, plus warm-up sets, supersets and drop sets • A rest timer docked at the bottom of the screen, with +30s and Skip • Your workout on the Lock Screen and in the Dynamic Island, with the current set and your rest countdown • Voice logging: say "bench press, three sets of eight at 185" and it is logged • 700+ exercises with images and animations, filtered by equipment, type, difficulty or body position • Cardio: distance, time and pace, with heart rate or power • Pounds or kilograms, miles or kilometers PROGRESS YOU CAN READ • Personal records for every exercise • Where you stand: see how your bench press, squat, deadlift and runs compare with other lifters and with adults worldwide • Search your history for any exercise, routine, muscle, gym or note • A line under every exercise that says whether you are improving, holding steady or stuck on a plateau • A muscle recovery map that shows what is ready to train today • Train at more than one gym: machine and cable weights are compared only within the same gym, so a new gym never breaks your records 85 BADGES TO COLLECT Collector cards from common to legendary.
