## What is IronFast?

**IronFast — the safest, most honest fasting app at the best price.**

Track your intermittent fasting with a beautiful timer, real-time fasting phases, and safety features that actually care about your health.

**WHY IRONFAST?**
Most fasting apps skip the important stuff — safety screenings, medical disclaimers, honest science. We built IronFast to do it right. Every health claim includes a disclaimer. Every extended fast includes safety check-ins. And we block users who shouldn't be fasting (pregnant, eating disorders, Type 1 diabetes) instead of taking their money anyway.

**FREE FEATURES:**
- Beautiful circular fasting timer
- Popular plans: 12:12, 14:10, 16:8, 18:6
- Real-time fasting phases (Fed → Fat Burning → Ketosis)
- Phase descriptions with honest scientific disclaimers
- Push notifications (start, goal reached, phase transitions)
- 7-day fasting history
- Streak tracking
- Daily hydration tracker
- Safety symptom checker during fasts
- Medical disclaimer, age verification, health screening

**IRONFAST PRO ($3.99/month or $24.99/year):**
- All fasting plans including 20:4 Warrior, 36-hour Monk, 5:2, and custom
- Detailed stats and weight tracking
- 72-hour automatic safety cap
- Refeeding guidance after extended fasts
- NEDA helpline access for those who need support

**HONEST SCIENCE:**
Every fasting phase description and health claim in IronFast is labeled "Based on available research" because that's the truth. We don't oversell. We don't make miracle claims. We give you the facts and let you decide.

**YOUR DATA, YOUR DEVICE:**
All data stays on your device. No accounts. No cloud sync. No tracking. No ads. Ever.

**SUBSCRIPTION INFORMATION:**
IronFast Pro is available as an auto-renewable subscription.
- Monthly: $3.99/month
- Annual: $24.99/year
