Unfed: Fasting Timer & Phases

Understand Your Body

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.

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.
