WHY FASTORY

hydration and journal, then answers in your language.
• AI insight after every fast — a tailored takeaway the moment you finish, powered
by GPT, not a canned tip.
• Weekly & Monthly AI Reviews — your progress recapped with concrete next steps.
TRACK EVERYTHING
• Flexible fasting timer with stages — 14:10, 16:8, 18:6, 20:4, OMAD, 36h or custom.
• Goal-reached celebration, eating-window reminders and smart stage notifications.
• Weight & BMI tracking with goal progress and clean charts.
• Daily journal — mood, body symptoms, meals, photos and notes.
• Stats — total fasting hours, streaks, mood trends and pattern insights.
• Guided programs (7-day, 28-day, OMAD) to build the habit.
• 53 achievements and tier badges to keep you going.
