## What is SmartHIIT?

A free interval timer and guided workouts from 10 to 30 minutes, at home, no equipment.

FREE HIIT AND TABATA TIMER
Pick Tabata (20/10), 30/30, 40/20, 45/15 and more, or set your own work and rest from 10 seconds. See the total time before you start. Voice and beeps mark every change, even with the screen locked or your music playing. Free, always.

GUIDED WORKOUTS WITH A 3D COACH
See every move in large size while you train, with a timer you can read even with your phone on the floor. Switch the camera between front, angled and side whenever you like. During rests the video already shows the next exercise, and the coach's voice tells you what's next.

A PLAN THAT FITS YOUR ROUTINE
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.

CONSISTENCY YOU CAN SEE
The Today screen shows your week, your next workout and how many weeks in a row you've trained. Track workouts, active minutes and estimated calories. Take the 1-minute fitness check to see your progress. Connect Apple Health to save your workouts there.

FOR BUSY DAYS
Sessions from 10 to 30 minutes, a no-jumping option, a short version, reminders at the time you choose and a widget with your next session.

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.
