Your eyes are part of your daily wellness ritual. IRIS is a privacy-first wellness tracker that uses visual patterns from your eyes to deliver personalized wellness insights — all processed on your device. No photos are stored. No data leaves your phone unless you choose to share it. WHAT MAKES IRIS DIFFERENT Unlike traditional period trackers, IRIS combines visual wellness patterns from your eyes with daily check-ins and Apple Health data to build a complete picture of your wellness across your entire cycle. YOUR DAILY WELLNESS IN 10 SECONDS Scan your eye. Get six estimated wellness scores: energy, stress, recovery, hydration, fatigue, and inflammation. Track trends over 7, 30, and 90 days. CYCLE-AWARE COACHING Smart coaching tips adapt to your current phase — menstrual, follicular, ovulation, or luteal. IRIS learns your patterns and suggests nutrition, movement, skincare, and recovery strategies tailored to you. EVERY LIFE STAGE Whether you have a regular cycle, are pregnant, postpartum, or navigating perimenopause and menopause — IRIS adapts symptom tracking, insights, and coaching to your stage of life. DAILY CHECK-IN Log mood, energy, sleep, symptoms, and lifestyle factors. IRIS cross-references your check-in with your scan data to surface patterns you might miss. SHARE WITH YOUR DOCTOR Generate a professional PDF wellness report with cycle summaries, 30-day averages, symptom patterns, and trend analysis to share with your healthcare provider if you choose. PRIVACY BY DESIGN - Photos analyzed on-device and immediately discarded - Only numerical wellness scores are stored - Server sync is opt-in with explicit consent - No ads. No third-party data sharing. ALSO INCLUDES - Apple Health integration (HRV, wrist temperature, sleep) - Cycle calendar with phase predictions - Partner mode for sharing phase info with loved ones - Gamification: streaks, milestones, monthly progress - Community tips from other women in your phase - Available in 9 languages IRIS PREMIUM Advanced insights, trend tracking, cycle coaching, and wellness reports require an active IRIS Premium subscription. Subscriptions auto-renew monthly or annually. Cancel anytime in your device Settings > Apple ID > Subscriptions. IMPORTANT: IRIS is a wellness tool only, not a medical device. Wellness scores are estimates for personal awareness and are not medical diagnoses, assessments, or treatment recommendations. Always consult a qualified healthcare provider for medical concerns.

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.
