Most fasting apps show a simple countdown. Unfed visualizes your progression through 5 distinct metabolic phases—from Fat Burning to Deep Ketosis—with a beautiful circular timer that makes every fast a visual achievement. TRANSFORM YOUR FASTING EXPERIENCE Stop counting hours blindly. Understand what your body accomplishes during each moment of your fast. • Metabolic Phase Visualization: Unlike competitors with basic timers, Unfed shows your progression through 5 phases (Anabolic → Catabolic → Fat Burning → Ketosis → Deep Ketosis) with color-coded segments. See completed phases, your current phase with live progress, and upcoming phases—all in one glance. • Elegant Circular Timer: Premium "donut-style" design with pastel colors on deep black backgrounds. Calm, zen, and motivating—not clinical neons. • Privacy-First: Your data stays on your device by default. No account required to start. Cloud sync is 100% optional. • Designed for Understanding: Each phase includes clear explanations so you know exactly what's happening in your body. FREE FEATURES (ALWAYS FREE) The core fasting experience is completely free, with no trial limits: • Circular Timer with 5 metabolic phases visualization • Popular Protocols: 16:8, 18:6, 20:4, OMAD (23:1), 24h, 36h fasts • Phase Education: Understand what happens in your body during each phase • 7-Day History: Review your recent fasts • Streak Tracking: Build consistency with visual streaks • Smart Notifications: Start/end reminders and phase transitions • Dark & Light Mode: Follows your system preference UNLOCK PRO Support development and unlock powerful tools: • Unlimited History: Access all your fasting data forever • Weight Tracking: Monitor your progress with beautiful charts • Custom Protocols: Create fasting schedules tailored to your goals • Native Widgets: iOS home screen widgets (Small/Medium/Large) • Detailed Phase Info: Extended scientific explanations of metabolic phases POPULAR FASTING PROTOCOLS SUPPORTED • 16:8 — The classic. Fast 16 hours, eat in an 8-hour window. • 18:6 — Extended fat-burning window for faster results. • 20:4 (Warrior) — Advanced protocol for experienced fasters. • OMAD (23:1) — One meal a day for maximum autophagy. • 24h / 36h — Longer fasts for deep ketosis and cellular renewal. • Custom — Design your own protocol based on your schedule. UNDERSTAND YOUR METABOLIC PHASES Unfed educates you on what happens during your fast: • Anabolic (0-4h): Digestion and nutrient absorption • Catabolic (4-12h): Glycogen depletion begins • Fat Burning (12-16h): Your body switches to fat for fuel • Ketosis (16-24h): Ketone production increases, mental clarity peaks • Deep Ketosis (24h+): Autophagy activated, cellular repair maximized Each phase is color-coded and clearly displayed on circular timer, so you always know your metabolic state. WHY UNFED EXISTS I'm a solo developer who believes fasting apps should help you understand your body, not just count hours.
