Get years of your life back from quitting smoking

It turns your smoking history into one number: how much of the time smoking has taken you have won back, and how much more there is to win. A daily check-in keeps it current.

Three published sources. A US Social Security Administration period life table for the baseline, Jackson et al. in Addiction 2025 for what a cigarette costs, and Jha et al. in the New England Journal of Medicine 2013 for what quitting returns. The methodology page shows the full math and a worked example.

No. It will not tell you when you are going to die. It is a motivational estimate built from population averages, and two people with identical answers can have very different outcomes. It does not diagnose, treat or prevent anything. Talk to a doctor or a quitline about stopping smoking. In the US, that is 1-800-QUIT-NOW.

Yes. The three calculators on this site are free, need no account, and give the same numbers the apps give.

Not to use it. The free app asks for no account, no email address and no payment details, and the calculators on this site ask for nothing either. Premium uses your email address only when you want it on more than one device: you enter it once, we send a six digit code, and that is what carries your subscription to your other devices.

On your device. Without a subscription nothing you log ever leaves it. With one, your check-ins can follow you between your iPhone, Android phone, Mac and PC: they are encrypted on your device first, with a key made on your device that is never sent to us, so we store only the encrypted result and cannot read your history.

You log it and the number moves. It moves down as well as up on purpose: a counter that only ever improves is not believable, and being honest with it is the point.

Nothing resets. Days are editable afterwards, and an untouched day is treated as your usual rate, so the estimate never flatters you for forgetting.

iPhone, iPad, Apple Watch and Mac from the App Store, Android and Wear OS from Google Play, and Windows from the Microsoft Store or straight from this site. The download page says where each version comes from.

Free forever: the time you have won back, daily check-ins, one photo of your reason, the recovery curve, your smoke-free day count, your full history, a shareable milestone card, your next health milestone, and the Mac and Windows apps. Premium adds money saved, widgets, the Watch and Wear apps, export, the quit plan, the full recovery timeline, the app lock and sync across every device you own.

You cancel and keep everything. After 365 smoke-free days, counted up one smoke-free day at a time, you cancel your subscription and keep every paid feature permanently at no charge. You do the cancelling, because no developer can do it for you in any store. Smoking again takes nothing away. Only starting a new attempt, which is yours to start, needs a new subscription.

Yes. Android phones and Wear OS watches get it from Google Play. Windows PCs get it from the Microsoft Store or as a download from this site. The number, the check-ins and Premium work the same everywhere, and one Premium subscription covers up to 10 devices.

It is as accurate as the three published studies behind it, applied to population averages. The apps and this site run the same test cases, so every platform gives the same figure to the minute. Your own outcome also depends on things no calculator can see, like your genes and your other health. The methodology page shows every step.

Yes, in two ways. Cancel any time and Premium keeps working until the end of the month or year you paid for. After 365 smoke-free days, you can cancel and keep every paid feature for good at no charge.

Your email address, your encrypted synced history and your reason photo are deleted, and every device is signed out. The record of a purchase stays so billing and refunds still work, and the check-ins on your own devices stay there until you uninstall the app. A running subscription keeps going until you cancel it where you subscribed.

The free version never expires. For Premium, the yearly plan starts with 7 days free for new subscribers, on this website, in the App Store and on Google Play, and then bills the yearly price. The monthly plan bills when you subscribe.

Quitting later returns less than quitting earlier, and it still returns real years. There is a whole guide on that question, worked through with real numbers.
