CycleFasting
Read full descriptionHide full description
Women run on a 28–32 day hormonal cycle, unlike men who run on a 24 hour cycle. That is why the female body is not designed to eat or fast the same way every day. CycleFasting is the first fasting app designed specifically for women's biology. You were never meant to eat and fast the same way every day. CycleFasting adapts to your menstrual cycle so you fast when your body is ready and nourish when it needs support. Your cycle has four phases, and each one changes how your body responds to fasting, nutrition, and energy. CycleFasting follows your rhythm so your eating window, fasting targets, nutrition guidance, and meal recommendations work for your hormones. During your Fasting Phases, your body is naturally more insulin sensitive and primed for fat burning. The app guides you through optimized fasting windows while helping you keep net carbs low for maximum metabolic benefit. During your Estrogen Dominant Phase, energy begins to rise and your body can tolerate moderate fasting. The app adjusts your eating window and opens your nutrition targets accordingly. During your Progesterone Dominant Phase, fasting can increase cortisol and work against your body. CycleFasting shifts into nourishment mode and guides you toward magnesium rich foods, healthy fats, and complex carbohydrates your body may naturally crave. Connect your wearables: Apple Health, Health Connect. CycleFasting can detect when your period begins using skin temperature data and predict your next cycle. Features: - AI Food Scanner with phase aware nutrition feedback - Smart eating window that adapts to your cycle phase - Extended fasting protocols such as 17h, 36h, 48h and 72h available during Fasting Phases - Temperature based period detection via wearables - Cravings Translator that helps you understand what your body may need - Nourishment mode during the Progesterone phase - Daily symptom check in and prediction engine - Net carb and protein tracking without calorie counting - Phase specific recipe library - AI Nutrition Coach personalized to your cycle day - Apple Health, Health Connect Your biology is not a limitation.
