## What is Fastwell?

Fastwell is an honest intermittent fasting timer that shows you what's actually happening inside your body — right on your Lock Screen and Dynamic Island.

Start a fast, and Fastwell tracks your journey through the real metabolic stages: glycogen depletion, fat burning, ketosis, and autophagy. No guessing, no gimmicks — just a clear, science-based timeline of where you are and what comes next.

The core is free forever. No fake trials, no surprise charges, no locking your own timer behind a paywall.

WHY FASTWELL

• Fasting stages on Live Activity & Dynamic Island — glance at your phone and instantly see if you've hit fat burning or ketosis, without opening the app.
• A timer you can actually trust — start, pause, edit your start time, and finish honestly.
• Popular windows built in — 16:8, 18:6, 20:4, OMAD, or set your own custom window (12–36h).
• Streaks & progress — build momentum with streaks, best-streak tracking, weekly stats, and trend charts.
• Weight & BMI tracking — log your weight, see trends, and sync with Apple Health.
• Home Screen & Lock Screen widgets — your current stage and countdown, always visible.
• Smart reminders — get notified when your fast completes or your eating window is about to close, with quiet hours respected.
• Learn the science — clear, no-hype articles on fasting basics, metabolic stages, weight, and longevity.

HONEST BY DESIGN

Your timer, windows (16:8/18:6), history, streaks, and Live Activity are free — forever. Fastwell Premium unlocks deeper insights, locked custom windows, and expert stage breakdowns, but the essentials never disappear.

Fastwell Premium (optional)
• Weekly and Yearly plans available.
• The Yearly plan includes a 7-day free trial.
• Payment is charged to your Apple ID account at confirmation of purchase.
• Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period.
