## What is Hour Zero?

Hour Zero is the honest fasting timer.

The timer, every protocol, streaks, widgets, your complete history, weight tracking, and the Apple Watch app are free — forever. No account. No credit card. No trial that quietly bills you. Your data lives on your phone; we never see it.

WHAT YOU GET, FREE
• A beautiful fasting timer with a live zone ring — watch your fast move from Fed through Fat Burning
• Every protocol: 16:8, 18:6, 20:4, OMAD, or set your own
• A daily rhythm: tell Hour Zero when you eat and it runs your day, with reminders at the boundaries
• Full history and streaks — your record is never held hostage
• Home Screen and Lock Screen widgets, plus a Live Activity that keeps the timer on your lock screen
• Apple Watch app and watch-face complications — start, end, and track from your wrist
• Weight logging with two-way Apple Health sync

HOUR ZERO PRO — $14.99 ONCE, NEVER A SUBSCRIPTION
• Insights and trends: completion rate, 30-day patterns
• CSV export of your full history — it's your data
• Every future Pro feature included. No upsells, no new tiers.

PRIVATE BY DESIGN
No servers. No analytics. No advertising. Nothing to collect, because everything stays on your device.

Hour Zero is a general-wellness tool, not medical advice, and does not diagnose, treat, or prevent any condition. Talk to your doctor before fasting — especially if you are pregnant or nursing, have diabetes or low blood pressure, take medication, or have a history of disordered eating.
