Flow Fasting Tracker vs PortionCheck

Your cycle changes everything. Most fasting apps ignore it. Estrogen, progesterone and testosterone each shift your metabolism, energy and hunger differently across your cycle. Flow Fasting tracks where you are and guides your fasting practice around it, so you always know the right window for your phase, and why it works. Whether you struggle to fast during your luteal phase, feel unstoppable in follicular, or want to understand why your results change week to week - Flow Fasting gives you a science-backed approach for every phase of your cycle. FIVE PHASES. FIVE DIFFERENT FASTING STRATEGIES. Bleed: Rest and restore. Shorter windows, nourishing breaks. Follicular: Your peak window. Longer fasts, stronger results. Ovulatory: High energy. Maintain momentum and protect your gains. Early Luteal: Shift with your hormones. Moderate and consistent. Late Luteal: Listen to your body. Gentle windows, no force.
