Lose weight at home with short HIIT workouts, no equipment, guided from start to finish. YOUR WEIGHT-LOSS PLAN Choose your goal, experience, time per workout and how many days a week you want to train. SmartHIIT builds a four-week plan of bodyweight circuits that gets a little harder every week and adapts to your feedback: too hard, and the next session eases off; too easy, and it moves ahead. When a phase ends, a new one starts with new exercises. A FULL-SCREEN 3D COACH See every move in large size while you train, with a timer you can read even with your phone on the floor. During rests the video already shows the next exercise, and the coach's voice tells you what's next. CALORIES AND PROGRESS See estimated calories for every workout and for the week, your active minutes and your streak. Take the 1-minute fitness check to track your progress. Connect Apple Health to save your workouts there. FITS YOUR ROUTINE Sessions from 10 to 30 minutes, a no-jumping option, a short version for busy days, reminders at the time you choose and a widget with your next session. FREE INTERVAL TIMER Tabata, 30/30, 40/20, 45/15 and more, with voice and beeps, even with the screen locked or your music playing. Free, always. TRY IT FIRST Your first plan session is free, no subscription needed, with the full-screen coach included. SMARTHIIT PRO Pro unlocks the full plan and its next phases, the full-screen coach in every workout, the full library of workouts and 3D exercises, the routine editor and the AI tools. Monthly and annual subscriptions include the same features. Prices, billing periods and eligible introductory offers are shown before purchase. The annual plan is billed for the full year at once. Subscriptions renew automatically unless canceled at least 24 hours before the end of the period. Manage or cancel them in your Apple Account subscriptions. Your history, saved routines and the free timer remain available after a subscription ends. Calories are estimates. SmartHIIT does not assess injuries or replace individual professional advice. Watch the moves, warm up at your own pace and stop if you feel pain or discomfort. Privacy: https://smarthiit.dltechdigital.com/privacy/ Terms: https://smarthiit.dltechdigital.com/terms.html
