Key Features:
Real-Time Metabolic Stages Stop guessing and start knowing. CYOFast tracks your journey through five distinct metabolic zones: Anabolic, Catabolic, Fat Burning, Ketosis, and Autophagy. Visualize your progress as you shift from digesting food to burning fat for fuel.
Flexible Fasting Presets Choose from popular fasting protocols including Circadian Rhythm (13 hours), 16:8, 18:6, the Warrior Diet (20:4), and OMAD (One Meal A Day).
Custom Goals & Timer Your body, your rules. Set custom fasting durations to match your lifestyle. The smart timer keeps running in the background, ensuring you never lose track of your progress even when the app is closed.
Detailed History & Analytics Stay consistent with a comprehensive history calendar. Visual progress rings highlight your successful days, while detailed analytics help you track weight trends and fasting consistency over time.
Premium Dark Mode Design Enjoy a beautiful, battery-saving dark interface featuring fluid animations and data visualizations that make tracking your health a daily pleasure.
