PuffCurve: Quit Vaping Tracker

You don't have to quit tomorrow.

PuffCurve counts your puffs and builds a plan that steps down day by day — until it reaches zero. Every plan ends at zero. That's the whole point.

ONE TAP, FROM YOUR HOME SCREEN
Add the widget and log a puff without opening the app. No searching, no menus, no waiting. The counter is yours forever — it is never capped and never behind a paywall.

A PLAN YOU CAN ACTUALLY SEE
Your plan is a day-by-day curve, not a vague goal. You can see today's number, tomorrow's, and the day it reaches zero. Nothing is guessed: your plan is built from your own numbers and can never ask you to vape more than you already do.

ONE SLIP DOESN'T UNDO THE REST
Had a bad day? Your plan recalculates around it. Your streak counts days on plan, not days of perfection — a hard day pauses it, it doesn't erase it. There is no scolding here, and no starting over.

RIDE OUT A CRAVING
A three-minute timer with a breathing rhythm, one tap from the main screen. It picks up where it left off if you get interrupted. Also yours forever.

WATCH THE MONEY COME BACK
See what you haven't spent, day by day and month by month, in your own currency.

YOUR DATA STAYS ON YOUR PHONE
No account. No email. No sign-up. Your puff log never leaves your device. Export everything as CSV or JSON whenever you want, or restore from a backup file you made yourself.

QUIT WITH FRIENDS (OPTIONAL)
Start a small group of up to four with a six-letter code. You each see whether the others are under target today and how many days they've been on plan. Never puff counts. And if you like, see how many others are on the same day of their plan as you.

SEE YOUR USAGE
Daily, weekly and monthly charts in puffs or estimated nicotine (mg), your hardest hour, and what sets your cravings off.

WHAT'S INCLUDED WITH A SUBSCRIPTION
The full taper curve and recalculation details, your history and insights (hourly patterns, plan vs. actual), backdated corrections, and automatic day cards. The counter, today's target, the craving timer and your milestones are yours whether you subscribe or not.

Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel in Google Play > Payments & subscriptions.

Not a medical device. PuffCurve is not a treatment programme and does not give medical advice. If you want clinical support to stop, talk to a doctor or a local quit service.
