New: Live Activity craving timer in the Dynamic Island. Beat the next craving in 5 minutes.
Day One is designed to help users reduce and quit nicotine consumption.
Track every puff. Watch your lungs come back. Day One turns the science of recovery into a clear, beautiful daily ritual.
WHAT'S INSIDE
• Puff counter with one-tap logging — Lock Screen widget, Home Screen widget, and Live Activity in the Dynamic Island
• Day-by-day withdrawal timeline sourced from the American Cancer Society, CDC, and NHS — see what's coming before it hits
• Animated lung-recovery visualization that updates as your streak grows
• 5-minute Live Activity craving timer with one-tap Resisted / Gave In / End
• Milestone share cards for Day 1, 3, 7, 14, 30, 60, 90, 180, and 365 — keep the wins close

• Trigger map: tag what made you crave, see your pattern over weeks
• Money saved tile — every avoided puff adds up
DESIGNED FOR THE HARD DAYS
We don't shame relapse. "Start a new Day One" replaces "reset streak." History is preserved. The streak counter is a tool, not a verdict.
HEALTH INFORMATION
The recovery timeline and health information in Day One is based on guidance from the American Cancer Society, CDC, and NHS — cited in-app under Sources & References. Day One is an educational and motivational tool, not a medical device, and does not provide medical advice. Talk to a healthcare professional about quitting and about any symptoms you experience.
PRIVACY
No account required. No data linked to your identity. Analytics are anonymous. Your puff log stays on your device and (optionally) in your iCloud.
SUBSCRIPTION
Day One offers a Withdrawal tier ($4.99/week with a 3-day free trial). At Day 30 of your streak, you unlock a Maintenance tier ($0.99/month, forever) as a reward — a gift, not a paywall.
Cancel anytime in Settings. Auto-renews until canceled. Terms: https://renolabshq.com/day-one/terms
