Fastual: Autophagy Timer

Fastual - Your Fasting Ritual, Visualized

See what's happening inside your body as you fast. Fastual tracks your metabolic phases in real time - from anabolic digestion through ketosis and autophagy - with a calm, organic interface designed for daily use.

REAL-TIME METABOLIC PHASES
Watch your body progress through 7 fasting stages: Anabolic → Catabolic → Fat Burning → Ketosis → Autophagy → Deep Repair → Extended. Each phase comes with a clear explanation of what's happening biologically, so you understand your fast - not just time it.

ONE-TAP FASTING TIMER
Start fasting instantly. Choose from popular protocols like 16:8, 18:6, 20:4 (Warrior), or OMAD (23:1). The expanding ring visualizes your progress without anxiety - no ticking clock, just calm momentum.

STREAK & HISTORY TRACKING
Build consistency with streak tracking. Review your complete fasting history, see your average fast duration, and watch your streaks grow over time. Every completed fast is logged automatically.

WATER TRACKER
Stay hydrated during your fast with a quick-add water logger. Customize your glass size, set reminders, and keep your hydration on track - all without leaving the timer screen.

PRIVACY BY DESIGN
Your biological data stays on your device. No account creation. No cloud sync. No tracking. Fastual works entirely offline - because your fasting journey is yours alone.

DARK MODE FIRST
The "Bioluminescent" interface is designed for late-night fasting checks and early-morning starts. Reduced eye strain, premium aesthetics, and a design that feels like a ritual - not a fitness app.

FASTUAL IS FOR YOU IF:
• You want to understand your metabolic phases, not just count hours
• You value clean, calm design over feature-heavy fitness apps
• You prefer privacy and offline functionality over social features
• You're building a sustainable fasting habit through streaks and consistency
