Fasting the "standard" way left me exhausted, losing hair, and spotting between periods. The problem wasn't fasting — it was fasting against my hormones. Most intermittent fasting apps were built for men's 24-hour hormone cycle. Women run on a monthly cycle, and the fast that feels easy one week can wreck your energy the next. FastingLady is the fasting tracker built for that reality: it syncs your fasts to your menstrual cycle, so you fast when your body is primed for it — and rest when it isn't. Inspired by Fast Like a Girl by Dr. Mindy Pelz, FastingLady connects with Apple Health to build a personalized fasting plan around your four hormone phases. Your Four Phases - Power 1 (Days 1–10): Estrogen is rising — your best window for longer fasts and fat burn. - Manifestation (Days 11–15): Energy and confidence peak around ovulation — moderate fasts, whole foods. - Power 2 (Days 16–18): Hormones dip as progesterone builds — steady fasts or a 24-hour reset day. - Nurturing (Days 19–30): Progesterone is dominant — gentle or no fasting, smart carbs, more rest. Fasting Plans Matched to Your Goal Tell FastingLady your goal — hormone balance, fat burn, or gentle cycle awareness — and get a plan matched to it: - Simple Reset: 13–17 hour fasts that shift with each phase. - Advanced Reset: 13–24 hour fasts, with 24-hour reset days in your Power phases. Change your plan anytime in Settings, and your current cycle updates instantly. Features - Fasting Timer & Tracker: Start and stop with one slide. Forgot to start? Backdate a fast to any time yesterday. - Cycle Sync from Apple Health: Your period syncs automatically from Apple Health — no manual logging. Supports irregular cycles longer than 30 days. - Weight Trends by Phase: Your weight syncs from Apple Health and is charted against your cycle, so you can see why the scale moves when it does. - Daily Hormone Guidance: Every day, see your hormone levels, how you may feel, what to eat, and the ideal fasting duration for that day. - Cycle Calendar & Dashboard: Your fasting history, period, weight, and cycle insights in one place. - Home Screen Widget: Your fasting timer right on your home screen. - Private by Design: Your cycle and weight data are read on your device from Apple Health. Nothing ever leaves your phone. - iCloud Sync: Your fasting data stays in sync across your devices. FastingLady Unlimited (Premium) - No ads, ever - Apple Watch app — track your fast from your wrist - Smart fasting notifications - Advanced dashboard insights Why I Built FastingLady After practicing intermittent fasting, I noticed great health benefits — but also hair loss and irregular spotting. Nothing explained why until I discovered Fast Like a Girl by Dr. Mindy Pelz. Following a fasting approach designed for women, my hair stopped falling out, my weight stabilized, and my period became more regular. I realized fasting and menstrual health are deeply connected. Since I couldn't find an app that tracks both fasting and the menstrual cycle together, I created FastingLady — a daily companion for women who want to fast smart and stay in tune with their period.
