Day One - Quit Nicotine
Stop nicotine, Zyn, save money
Free · In-App Purchases · Designed for iPhone. Not verified for macOS.
Free to try — the puff counter, craving timer, and your recovery so far. Already quit? Set your real quit date and claim every milestone you've already earned.
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

• Animated lung-recovery visualization that updates as your streak grows
• 5-minute Live Activity craving timer with one-tap Resisted / Gave In / End

• 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
