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.
