Best Quit Smoking Apps: An Honest Comparison
Quick answer: If you want the deepest evidence-based toolkit and do not mind a paid tier, Smoke Free is the most thoroughly built app here, with 40+ techniques and a craving map, on both iPhone and Android. If you would rather pay nothing at all and trust the source, quitSTART is made by the U.S. National Cancer Institute's Tobacco Control Research Branch with the FDA and carries no ads and no in-app purchases — for many people it is the better first download than anything commercial, ours included. And if loneliness is what breaks your quits, QuitNow!'s ex-smoker community is the feature that matters. Full disclosure: we make one of the six apps below, and we have tried to describe the other five the way their own makers would.
Quit-smoking apps are unusually easy to choose badly, because the thing that decides whether you stay quit is not the feature list — it is whether you still open the app in week three. Different people fail for different reasons: some need a plan, some need a distraction at 9pm, some need other humans, some need to not be nagged. The apps below are genuinely good at different ones of those.
Everything here was checked against each app's own App Store or Google Play listing in August 2026, and the sources are at the bottom of the page. We have not quoted star ratings, success rates, or download counts. Success-rate claims in this category are especially difficult to verify independently, so where a maker makes one, we say that it is their claim.
How did we compare them?
- Platforms. Whether the app exists on both iPhone and Android, which matters if you are quitting alongside a partner or friend.
- Price model. Free, ad-supported, subscription, or one-time — and where the paywall sits relative to the features you will actually lean on.
- Works offline. Cravings do not wait for signal. We only mark “yes” where the maker states it.
- Account required. A quit log is sensitive. Whether it leaves your phone is worth knowing on day one, not month six.
Where a listing does not address a point, the table says not stated. That is not a “no” — it means we could not verify it, and we would rather show a gap than invent a fact.

Smoke Free — the deepest toolkit
Smoke Free, by 23 Ltd, describes itself as “the app that science built,” and the feature set backs the ambition: over 40 different evidence-based techniques, plus the usual milestones for time quit, money saved, cigarettes not smoked and life regained. Its most distinctive tools are about cravings specifically — a map that shows you where your cravings congregate, notes for spotting patterns, and a graph showing them decreasing over time. That geographic view of your own triggers is something no other app in this list offers.
The free tier is substantial. Pro adds a daily “Missions” plan and an AI Quit Coach, which the developer states is proven to double your chances of quitting — their claim, made in their own listing, and one we cannot independently verify. There is also a higher “Blitz your Quit” tier with a plan tailored by a human advisor, booster check-ins, and 24/7 advisor access. Pro is sold through both subscription and one-time options, and the Google Play listing shows ads. It is on iPhone, iPad, Apple Watch and Android. If you want the most tools and the most structure, this is the pick.
QuitNow! — the one with other people in it
QuitNow!, by Fewlaps, was started in 2011 by a smoker who wanted to quit, and has since brought in addiction specialists. The home screen covers the fundamentals well — time since your last cigarette, cigarettes not smoked, money saved, life regained — but the reason to choose it is social. There is a chat full of other people who have quit, and every month the app hosts a live session with a smoking-cessation psychologist who explains approaches and answers attendees' questions in real time. There is also a structured quit-smoking course.
It runs on iPhone, iPad, Apple Watch and Android, and is free with a QuitNow PRO in-app purchase; the Android listing shows ads. If your previous quits fell apart because you were doing it alone at midnight, this is the app whose core feature addresses that directly — a live human community is something a private, offline app like ours structurally cannot give you.
Kwit — CBT with a game around it
Kwit's pitch is that quitting is easier when it is engaging. It combines cognitive behavioural therapy techniques with gamification: real-time statistics for smoke-free days, money saved, cigarettes avoided and health improvements; craving tools including guided breathing, mini-games and instant motivation cards; supportive community groups; and a library of expert-designed articles. Kwit describes itself as the first WHO-validated smoking cessation app.
It is on iPhone, iPad and Android, free to start, with premium sold through subscription tiers and a lifetime option. If gamified progress is what keeps you engaged — badges, cards, a visible streak you do not want to break — Kwit does that better than the more clinical apps here.
quitSTART — free, credible, no strings
quitSTART is a product of Smokefree.gov, created by the Tobacco Control Research Branch at the U.S. National Cancer Institute in collaboration with the Food and Drug Administration, with input from tobacco control professionals, cessation experts and ex-smokers. It is built and maintained by ICF International on their behalf.
It takes what you tell it about your smoking history and returns tailored tips, inspiration and challenges: preparation guidance before your quit day, badges for milestones, help getting back on track after a slip, healthy ways to manage cravings and bad moods, games and challenges as distraction, and a “Quit Kit” where you store the tips that work for you. It runs on iPhone, iPad and Android, and the Google Play listing shows no ads and no in-app purchases at all.
We want to be plain about this: if you are choosing your first quit app and you want maximum credibility for zero money and zero monetisation pressure, quitSTART is a better starting point than any commercial app in this list, including ours. It is also worth knowing that many countries run free national quitlines and text programmes alongside apps like this one, and those are usually the highest-value free support available.
EasyQuit — for people not ready to stop dead
EasyQuit's differentiator is its “slow mode”: rather than assuming you will quit abruptly, it builds a customised gradual reduction plan for people who feel their nicotine dependence is too strong for cold turkey. Around that sit a health countdown, money statistics with a savings target you can set as a treat, a personal diary, craving and trigger statistics, up to 62 motivational badges, and a memory game intended to occupy you past the few minutes an urge typically lasts.
It is on iPhone, iPad and Android; the Android listing shows ads, and the description references a Pro version for some features such as the trigger breakdown chart. Tapering is a legitimate approach for people who will not otherwise start, and EasyQuit is the app here built around it. If you are ready to set a quit date, the other apps will serve you better.
ClearLung — ours, and where it fits
Full disclosure: we make this one. Treat this section as the developer's own account, not an independent review.
We built ClearLung around two things the apps above mostly do not combine: structured CBT content, and a genuine privacy guarantee. There are 15 CBT therapy lessons on identifying triggers, challenging automatic thoughts and building coping strategies, and 10 guided mindfulness exercises including urge surfing and breathing techniques. An SOS craving button offers 5 instant relief techniques, 23 achievement milestones run from one hour to five years smoke-free, and a health improvement timeline shows your body's recovery. Slip tracking is deliberately non-judgmental — the description cites research that self-criticism after slips increases relapse rates. There is also a substitutes library for oral and hand fixations, a withdrawal symptom tracker with severity logging, a virtual companion that grows healthier as you stay smoke-free, streaks, and analytics on your top triggers and peak craving times.
The privacy side is the part we would point to in this comparison: everything is stored locally, the app has zero network permissions and uses a local database only, there is no account, no cloud sync, no data collection, no ads and no third-party tracking. That is also why it works entirely offline. The free tier includes core tracking, the quit timer, basic lessons and exercises, the SOS button and all 23 milestones; Premium adds the companion, the withdrawal tracker, the full lesson and exercise library, advanced analytics and the substitutes library.
Where we would not recommend it: we are iPhone and iPad only, so Android users should look at Smoke Free, QuitNow!, Kwit, quitSTART or EasyQuit. We have no community, no human coaching and no AI coach — if support from other people is what you need, QuitNow! or Smoke Free's advisor tier will serve you far better. We have no Apple Watch app. And we are a commercial app: if you want zero monetisation, quitSTART is the honest answer.
Worth saying: apps are support, not treatment. The interventions with the strongest evidence base remain behavioural support combined with stop-smoking medication, usually through a healthcare provider or a national quitline. Every app on this page works better alongside that than instead of it.
So which one should you install?
- You want the deepest toolkit and craving analytics: Smoke Free.
- You need other people: QuitNow!.
- You stay motivated by games and streaks: Kwit.
- You want free, credible and unmonetised: quitSTART.
- You are not ready to stop abruptly: EasyQuit.
- You want CBT content with nothing leaving your phone: ours.
Install one, not four. The app that helps is the one you still open on day 21, and having three of them makes that less likely, not more.
If you want to try ours
ClearLung is free to start on iPhone and iPad: CBT lessons, mindfulness exercises, the SOS craving button and all 23 milestones, with zero network permissions so nothing you log ever leaves your device. If one of the five apps above fits you better, use that instead — this page exists so you can choose with the facts in front of you.
