Luneva helps you sync intermittent fasting with your menstrual cycle — because your hormones change every week, and your fasting window should too. Most fasting apps treat every day the same. But your body doesn't work that way. Estrogen, progesterone, and testosterone shift throughout your cycle, affecting your energy, metabolism, hunger, and recovery. Luneva tracks where you are in your cycle and automatically adjusts your fasting recommendation to match. CYCLE-SYNCED FASTING Each phase of your cycle comes with a different fasting window. Luneva shows you the right goal for today — not a one-size-fits-all number. PERIOD & CYCLE TRACKING Log your period start and end dates. Luneva tracks your cycle history, calculates your average length, and helps you stay in tune with your body over time. FASTING TRACKER Start, log, and review your fasts. See your streak, average duration, and how often you hit your goal — all organized by cycle phase. HORMONE INSIGHTS Understand what estrogen, progesterone, LH, FSH, and testosterone are doing throughout your cycle — and how they affect how you feel, fast, and function. CYCLE CALENDAR See your entire month color-coded by phase. Add notes to any day. Plan ahead with a clear view of what's coming. PHASE GUIDE Deep-dive into each phase: what's happening in your body, what to eat, how to move, and how to make the most of your energy at every stage.

PCOS MODE A dedicated mode for those with PCOS — with adjusted fasting windows, phase descriptions, and nutrition advice built around hormonal variability.
