A quit smoking app will not make you quit. What a good one does is remove the two things that quietly end most attempts: forgetting how far you have already come, and having nothing to do at nine o'clock on a Thursday when the craving turns up.
We make one of the apps on this list, so weigh our entry accordingly. Everything below reflects what these apps do at the time of writing. App listings change often — check the current version before you commit to one.
What actually matters in a quit app
Most quit apps look similar in the screenshots. The differences show up in week three, when novelty has worn off. Four things separate the ones people keep from the ones they delete.
- It opens fast. A craving lasts a few minutes. A tool you have to hunt through three menus for does not get used during one.
- It survives a slip. Apps that reset your counter to zero the moment you have one cigarette are the single most common reason people uninstall. One cigarette on day nineteen does not undo nineteen days of healing, and your app should not pretend it does.
- It tells you something you did not already know. Days counted and money saved are motivating for a fortnight. Patterns — which hours you are actually at risk, and whether that is improving — keep being useful after that.
- It does not eat the money you are saving. A £40-a-year subscription against a habit you quit to save money is a strange trade unless you are genuinely getting £40 of use.
The main options
NHS Quit Smoking
Free, no ads, no upsell, and backed by the same organisation that runs the stop smoking services. It tracks days, money and health improvements, and nudges you toward local NHS support. It is deliberately simple, which is either the point or the limitation depending on what you want. If you only download one thing and you want the safest possible option, this is it.
Smoke Free
The most feature-dense of the popular options — extensive health milestones, craving logging, diary entries and a large body of in-app content. There is a free tier and a paid tier, and the more interesting features sit behind the paid one. Good if you like data and will actually use it. Heavy if you want to check in and get on with your day.
Kwit
Leans on gamification and CBT-style prompts, with levels, achievements and cards to read when a craving hits. The tone works very well for some people and grates on others, which is worth a free trial before paying. Also subscription-based for the full feature set.
Flair Quit Tracker
Ours, so read this with that in mind. It is a free iPhone app built around a once-a-day check-in rather than constant logging. You hold the orb, it records the day, and you see days smoke-free and money saved. Three things make it different from the list above: slip passes, so one bad day dents your streak instead of deleting it; a craving pattern view that works out which hours and days you are actually at risk and whether that is fading; and Craving SOS, a guided breathing tool sized to the roughly three minutes a craving takes to peak and pass. There is a weekly leaderboard against people who quit the same week as you, if that sort of thing motivates you, and an optional Flair Plus upgrade. The core is free. More on what it does, or download it on the App Store.
Your phone, with no app at all
Worth saying: a note on your lock screen with your quit date, and a recurring calendar reminder, beats a beautifully designed app you stop opening. Plenty of people quit with nothing but a rubber band and stubbornness. An app is a convenience, not a requirement.
How to choose between them
Pick on the basis of what you think will break your quit, not on feature count.
- If you expect to be undone by losing motivation, pick something that shows progress prominently and daily.
- If you expect to be undone by one bad night, pick something that handles slips without resetting you.
- If you expect to be undone by specific situations — the pub, the commute, the first coffee — pick something that tracks patterns so you can see the situations coming.
- If you want clinical backing above all, use the NHS app and book into a stop smoking service.
The uncomfortable part
No app on this list is a treatment. If you are physically dependent on nicotine, tracking your days does nothing for withdrawal. The intervention with the strongest evidence behind it is an NHS stop smoking service combined with the right nicotine replacement — free in the UK, and it roughly triples your chances compared with going it alone.
An app is the layer on top of that: the memory, the accountability and the thing to do with your hands while the pharmacology does its job. Used that way it is genuinely useful. Used instead of proper support, it is a scoreboard for a game you are losing.
If the missing piece for you is the physical ritual rather than the nicotine, that is a different problem — we have written about the hand-to-mouth habit and what helps once the nicotine is handled.
Frequently asked questions
What is the best free quit smoking app in the UK?
The NHS Quit Smoking app is the safest free pick, with no upsell and direct routes into NHS support. The Flair Quit Tracker is free too and goes deeper on streaks, craving patterns and in-the-moment breathing tools.
Do quit smoking apps actually work?
The evidence is modest but real for apps that include behavioural support, and much weaker for ones that only count days. They perform best alongside proper cessation support rather than instead of it.
Should I pay for a quit smoking app?
Only after using the free tier for a fortnight. If you are still opening it daily at that point, a subscription may be worth it. If you are not, no feature set will fix that.
What happens to my streak if I slip?
It depends on the app, and it is worth checking before you start. Some reset to zero. The Flair Quit Tracker uses slip passes, so a single cigarette costs you a pass rather than your whole record.
Is there an Android quit smoking app from Flair?
The Flair Quit Tracker is iPhone-only at the time of writing. Android users are well served by the NHS Quit Smoking app in the meantime.
App features and pricing described here were accurate at the time of writing and may change. The Flair Quit Tracker is a habit-tracking app, not a medical device, medicine or smoking cessation treatment. For clinical support, NHS stop smoking services are free and substantially improve your chances. Flair products contain no nicotine and are not suitable for under-18s.
