The first AI-powered app that adapts fasting, nutrition, and workouts to your hormonal cycle — not a generic plan.
Free to download · iOS · No credit card required
Most fasting apps were designed with male metabolic data. FemFast is different from the ground up.
Your fasting windows, meal timing, and nutrition targets adapt to your menstrual phase — follicular, ovulatory, luteal, and menstrual.
Our AI doesn't just start personalized — it gets smarter over time, adjusting to your logged symptoms, energy, and lifestyle patterns.
Built on the latest research in female metabolism and hormonal health — not borrowed from generic nutrition guidelines.
Workout recommendations match your hormonal energy — high-intensity in follicular phase, recovery-focused in luteal.
Phase-specific nutrition suggestions that help balance estrogen and progesterone — not just calorie counting.
Your AI wellness coach gives daily nudges based on where you are in your cycle, your goals, and how you're feeling today.
Tell us about your goals, cycle, and lifestyle. Takes 2 minutes — and the AI starts personalizing before you even open the app.
Receive a fully personalized fasting schedule, meal guidance, and workout plan — adapted to your current hormonal phase.
Track energy, mood, and progress. The AI learns from your data and fine-tunes your plan week by week.
