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.

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.
