Build muscle one set at a time. Log every set with one tap, and MassBuilder plans your next weight, so the bar gets heavier when you're ready. Check your form with the camera, set an alarm you can only stop by moving, say what you ate, and let four judges have opinions about your leg day. DAILY CHALLENGE - An alarm that keeps coming back until you've done your push-ups, squats, burpees or pull-ups, at once or in rounds. - The camera counts in real time, as strict as you choose. Missed reps? Appeal. - Stamps at 7, 30, 100 and 365 days, and props to unlock. - Want out? Hold Give up for five seconds. It costs a missed day, or an amount you pick in advance. Ill? Pause it. FORM CHECK - Stand your phone on the floor, side-on, and lift. It counts every rep in eight lifts and gives you up to three things to work on. ONE TAP PER SET - Your workout is a punch card. Tap a hole and the set is logged with reps, weight and time. - The rest timer starts by itself, on the Lock Screen too, with four games for the wait. - Lay your phone on its side and the set fills the screen, with the tempo and a cue to brace. - Warm-up sets, a plate calculator and your next weight planned: more when you hit your reps, a deload after three misses. WOD AND CARDIO - AMRAP, EMOM, For time, intervals, Tabata and Run & Stations, with the clock on your iPhone, wrist and TV. - A WOD for every day, benchmarks to beat and a builder for your own. - Running, cycling, rowing and more count in your week and streak, with calories and heart rate as you go. Outside, GPS maps your route. FUEL - Search the food database, scan a barcode, or say or snap what you ate, and AI picks the foods and grams. - Macros in grams, targets that learn what you burn, a weight forecast with an honest range, and meal prep from 100 recipes. YOUR YEAR IN CHARTS - Today is a board you arrange yourself: top sets, effort, records, recovery, tonnage in elephants and your year as holes. - Every lift has its own chart with your best set and estimated 1RM. Set a goal and see when you'll get there. - Measurements on a body figure, and progress photos behind Face ID. - My day: steps, sleep, stress and water, and a year of sleep and stress. - A wake-up alarm per weekday that can wake you as you start to move. PROGRAMS AND WORKOUTS - Fifteen programs, from 5×5 to bodyweight at home. Answer six questions, or say what you want, and MassBuilder finds the one that fits. Or build your own. - 317 ready-made workouts to filter by type, length and equipment. - Tell MassBuilder your equipment, places and injuries, and lifts are swapped for ones that fit. - Over 400 exercises as 3D figures you can turn, with the muscles and four cues. EIGHTEEN LOOKS - From Chalk and Blueprint to Rosé and Christmas. Your Apple Watch and Apple TV follow. APPLE WATCH, IPAD AND APPLE TV - Log sets and rest from your wrist and see your heart rate. Fuel too. - Your iPad does it all, in sync with your iPhone. - On Apple TV, your charts fill the room and your workout shows up big. THE BENCH - Four judges react to how you train, from the chicken who guards leg day to the sloth who notices when nothing happens. - Pick Kind, Honest or Brutal. Every Monday they judge your week, never how you look. YOURS - No account. Your log lives on your devices and in your own private iCloud. - Camera video never leaves your device. - Apple Health both ways: workouts and routes, effort, macros, weight, waist, water and your scale's weigh-ins. - Bring your log from another app, and export everything as CSV and JSON. No ads and no tracking. MassBuilder Pro, a subscription or a one-time purchase, unlocks every program, the WODs, focus mode, form check on every lift, Fuel with AI, measurements and photos, sleep and stress over time, every module and look, and your workout on Apple TV. MassBuilder Coach, a subscription for personal trainers, includes Pro. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
