Fasting, food, strength training and stretching — together in one ad-free app. HealthyFast helps you build a daily routine around the things that matter to you. Track your fasts, log meals, follow a workout and make time to stretch. Choose the screens you use, arrange them your way and open the app on your favorite. FASTING AT YOUR PACE • Follow your fast with a clear timer and progress ring. • Choose a fasting goal and get reminders to keep track. • Explore educational fasting phases with links to supporting research. • Review your fasting history over time. Fasting phases are general, time-based estimates. They do not measure your metabolism or tell you exactly what is happening in your body. MEALS, CALORIES AND MACROS • Keep your meals and daily nutrition in one place. • Describe or photograph a meal for an AI estimate of calories, protein, carbohydrates and fat. • Compare your intake with an estimated daily energy target based on your profile. • Follow weight and nutrition trends over time. AI estimates are approximate. Cloud AI is optional, requires sign-in and asks for your consent before sending meal descriptions or photos for processing. STRENGTH TRAINING • Choose a program suited to your experience and follow guided sessions. • Log sets, reps and weights, with exercise guides to help you along the way. • Use progression guidance and review your training history. • Create and organize your own programs. GUIDED STRETCHING • Explore stretching routines and programs. • Follow timed sessions with visual exercise guidance. • Save favorites and keep a history of completed sessions. YOUR APP, YOUR ROUTINE • Show the screens you need and hide the rest. • Reorder your menu and choose your favorite start screen. • Swipe between fasting, meals, training, stretching, Journal and Insights. • See your activity history and trends in one place. APPLE WATCH AND APPLE HEALTH • Follow your fast and log strength workouts on Apple Watch. • Keep fasting progress close with watch complications. • Connect Apple Health to bring supported steps, sleep, weight, nutrition and workout data into your overview. • Share supported meal, weight and workout entries with Apple Health when you grant permission. OPTIONAL CLOUD BACKUP Sign in to back up your data and restore it on another phone. Core tracking does not require a HealthyFast account. SUBSCRIPTIONS You can explore the app and set up your profile before choosing a plan. New users need a subscription to start tracking. Eligible existing users retain their basic access. Premium features require an active subscription. HealthyFast Premium is available monthly or yearly. Any available trial and the current price are shown before purchase. Payment is charged to your Apple Account at confirmation of purchase, or after an eligible free trial. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel your subscription in your Apple Account settings. HealthyFast is a wellness and education tool, not a medical device or a substitute for professional medical advice. Energy, nutrition and fasting information are estimates.
