CycleFasting

Women run on a 28โ€“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. It is your advantage. Download free. Premium unlocks extended fasting tools, the full recipe library, AI coaching, and more. Terms of Use: https://cyclefasting.lovable.app/terms-of-service

Built for your body, not his. Most fasting apps were designed around male physiology. One window, same hours every day, applied to everyone. That's not how your body works. You have a cycle, and your hormones change pretty much everything: hunger, energy, sleep, how recovery feels. Fastelle is built around that cycle instead of pretending it doesn't exist. Fasting that moves with your cycle Your hunger in week one is not the same animal as your hunger in week three. Fastelle knows where you are in your cycle and adjusts your windows accordingly. During your period it pulls things back. Through follicular and ovulation, when most women feel strongest, it lets you push a bit. Then in the luteal stretch, when cravings and fatigue usually spike, it eases off again. You stop white-knuckling through fasts that were never written with you in mind. See what's actually happening The timer walks you through the six stages of a fast, from rising blood sugar through fat burn into autophagy. Hour 14 looks different from hour 16, and the app shows you why, so the time stops feeling like dead waiting. Food that follows the same logic Log meals, calories, protein, carbs and fat in one place. Your daily targets shift with your phase, because day 2 you and day 14 you are basically two different people, nutritionally speaking. A plan that's actually yours No off-the-shelf protocol pulled from someone else's body. Your week is shaped by your cycle, your goals, and what you can realistically handle right now. You can see what's coming in the next phase, which makes it easier to plan groceries, workouts and social stuff around it. Progress you can see Fasting streaks, weekly hours, hydration, weight trend, nutrition. All in one view, so you can tell whether what you're doing is actually working. For PCOS, irregular cycles, and bodies that don't behave Fastelle works whether you've been fasting for years or you're just trying it this week. It doesn't assume your cycle is textbook regular. It doesn't assume your body is the same every day. For most women, it isn't. Download Fastelle. Full access to Fastelle requires an active subscription.
