Easy intermittent fasts, synced to your cycle. FastingBestie turns Apple Health data into fasting and life guidance that fits you. Most fasting apps give everyone the same plan: 16:8, every day, no matter where they are in their cycle. FastingBestie is different: a cycle-aware fasting tracker for women, built to help you fast with your body instead of against it. Connect Apple Health and FastingBestie can use your cycle, height, and weight data to personalize your fasting guidance. If your smart scale, wearable, or health app writes supported measurements to Apple Health, FastingBestie can bring them into your progress view. That can include Withings, Xiaomi, Oura, Whoop, and other devices that sync through Apple Health. You can also use FastingBestie with manual entry. Your cycle does not have to be textbook, and your period does not have to arrive on a perfect schedule. FastingBestie estimates your current phase from your own cycle length, then adjusts your fasting window through Menstrual, Follicular, Ovulatory, and Luteal phases. WHY GENERIC FASTING APPS FAIL WOMEN Most fasting advice is based on male physiology, where hormones follow a daily rhythm. Women's hormones shift across the menstrual cycle, affecting energy, cravings, water weight, training, sleep, and how well you tolerate longer fasts. FastingBestie helps you stop guessing. It recommends a fasting window that changes with your phase, goal, experience level, dietary preferences, and recent fasting history. APPLE HEALTH AT THE CENTER Bring your health data into one fasting view: * Sync period and cycle data from Apple Health * Import weight from Apple Health, including compatible smart scales and apps * See weight trends alongside your cycle phases * Log weight manually when you prefer * Keep HealthKit data on your device CYCLE-AWARE FASTING GUIDANCE Your fasting plan changes as your cycle changes: * Menstrual: gentle, nourishing fasts while your body resets * Follicular: more room to stretch your fasting window as energy builds * Ovulatory: supportive fasting while hormones peak * Luteal: shorter, gentler fasts before your next period No fixed calendar assumption. FastingBestie works from your cycle length. FEATURES BUILT FOR FEMALE BIOLOGY * Hormone-adaptive fasting timer with multiple protocols. * Daily fasting recommendation based on your current cycle phase * Apple Health cycle sync, with manual tracking as a fallback * Apple Health weight import and manual weight logging * Progress charts for cycle-related weight changes * Phase-specific food, movement, and wellness suggestions * Easy editing for past fasts and weight entries * Fasting-stage guidance as hours pass * Apple Watch companion app for tracking on the go FOR EVERY RHYTHM FastingBestie is made for real bodies and real cycles: * Irregular cycles * PCOS-friendly, gentler fasting support * Perimenopause and changing cycle patterns * Menopause, when fasting priorities shift toward sleep, muscle, and metabolic health * Beginners who want an easy fast * Experienced fasters who want smarter timing PRIVACY FIRST No account required. Health, cycle, fasting, and biometric data stays on your device. Apple Health imports are processed on-device and are never uploaded or shared. We never sell your health data.

Verdict

The call

The clearest difference is update cadence: FastingBestie at every 2 weeks against Fast's every 2 months. FastingBestie also leads on review sentiment (100% vs 75%) and rating (5.0 vs 4.7). Fast's advantage is ratings volume (3.3K vs 4) and iOS requirement (18.6 vs 26.2). On price, ads, in-app purchases and monetization model there is nothing between them.
