## What is Sundial?

Finally, a fasting timer you buy once and own for life. No subscription. No account. No quiz-funnel paywall. Just open it and start your fast.

Sundial is a calm, local-first tracker for intermittent fasting and OMAD (one meal a day). One quiet ring; a sun crosses the dial as your fast deepens. Warm paper-and-ember design, automatic dark mode. No neon, no confetti, no streak-shaming. It works fully offline from the very first tap.

WHY SUNDIAL IS DIFFERENT
- Pay once, $19.99. No $60-80/year renewals for a glorified timer.
- No forced sign-up, no quiz funnel, no data siphoning. Cloud backup is optional, never required.
- Fasting zones and stages are explained for free - learn what each stage is called, hour by hour. Most apps lock this away.
- Custom durations up to 72 hours - log any fast you choose, with no upsell.
- Retroactive editing: forgot to hit start or stop? Fix it, or log a past fast.
- Your eating window anchors to when you actually broke the fast - not a rigid schedule.

FREE FOREVER
- Timer for every protocol: 16:8, 18:6, 20:4, OMAD, 36h, and custom.
- Fasting zones and stage labels on the dial.
- History, calendar, streaks, and weekly stats.
- Weight, water, and mood logging.
- Gentle notifications for start, end, and milestones.
- Export everything to CSV or JSON in two taps. Your data is yours.

LIFETIME UNLOCK ($19.99, ONCE)
- Cloud backup and cross-device sync.
- Insights: deeper trends over time.
- The full Field Notes library of calm, readable articles - including a plain explainer of what autophagy is.

Everything you need to fast is already free. Lifetime is for going further, on your terms.

BUILT TO RESPECT YOU
Local-first and private by design. No ads, no data mining, no guilt loops, no upsell screens between you and your timer. A quieter way to keep time.

Sundial tracks time. It is not medical advice. Talk to a healthcare professional before changing how you eat or starting extended fasts, especially if you are under 18, pregnant, managing diabetes, or have a history of disordered eating.
