Your hormones are not on a 24-hour clock — so why is your fasting routine? Most fasting apps treat every single day the same. Your cycle is personal, and your energy, appetite, and wellbeing can feel different throughout the month. Fasted Harmony brings cycle tracking, fasting, nourishment, and movement together in one supportive plan. YOUR DAY, SYNCED Open Fasted Harmony each morning to "Your Day, Synced" — your personalized daily roadmap that unites your cycle phase, fasting targets, meals, and movement into one effortless view. See your current cycle context, a suggested fasting range, meals, and movement together. Predictions recalculate from your recent completed logs and show a likely range when timing varies. WHY WOMEN LOVE FASTED HARMONY: CYCLE-AWARE FASTING WINDOWS Say goodbye to rigid 16:8 schedules that leave you exhausted during your luteal phase. Fasted Harmony offers phase-aware fasting ranges and encourages you to shorten or skip a fast when hunger, symptoms, sleep, or recovery call for nourishment. HOME & LOCK SCREEN WIDGETS Glance at your current cycle day, phase, and fasting countdown right from your Home Screen or Lock Screen. Choose from gorgeous aesthetic themes like Soft Blush and Starry Night. LIVE ACTIVITIES & DYNAMIC ISLAND Keep tabs on your active fast in real time. Dynamic Island and Lock Screen tracking let you check your remaining fast time at a single glance without unlocking your phone. CYCLE-SYNCED WORKOUTS WITH INSTRUCTIONS Stop guessing how hard to push. Access tailored daily workouts matched to your energy — from energizing strength training during your follicular surge to restorative yoga and mobility when your body needs recovery. Every exercise includes step-by-step instructions and form cues. HORMONE-SUPPORTIVE RECIPES Explore wholesome recipes organized by cycle phase and filtered against your saved food preferences, dislikes, and allergens.
