QuitNow, Smoke Free, and QuitSure are good apps. They are older than us, they have far more users than us, and they are rated highly by those users. We are not going to pretend otherwise on a page you can fact-check in two taps.
There is one thing we do differently, and it is the reason ClariLung exists: those apps were built to help you quit smoking. ClariLung is built for the four things people actually quit — vaping, cigarettes, weed, and cigars — with a separate program for each.
| Covers | ClariLung | QuitNow! | Smoke Free | QuitSure |
|---|---|---|---|---|
Cigarettes The thing every quit app was built for. | Yes | Yes | Yes | Yes |
Vaping Disposables, pods, and box mods deliver nicotine differently from cigarettes. | Yes — device-aware | Not mentioned | Not mentioned | Yes |
Weed / THC Different withdrawal curve, different triggers, different language. | Yes | Not mentioned | Not mentioned | Not mentioned |
Cigars Occasional and ritual use, not a daily pack habit. | Yes | Not mentioned | Not mentioned | Not mentioned |
“Not mentioned” means exactly that — the app’s own App Store listing doesn’t say it covers that substance. It is not a claim the feature is missing. These are actively developed apps and any of them may add something tomorrow, or support something today without advertising it. Checked 19 August 2026; tap any app name above to read its listing yourself.

Smoke Free and QuitNow have been shipping for over a decade and have tens of thousands of ratings between them. ClariLung launched in 2026 and has barely any. If a long public history is what you want to trust, that is a fair reason to pick them.
A bigger user base means a busier forum and more people awake at 3am when you need someone. Ours is small and growing.
Smoke Free in particular leans on published cessation research and describes itself as “the app that science built”. We cite the evidence our health timeline is built on, but we have not run trials of our own.
In their own words, from their App Store listings on 19 August 2026:
“QuitNow will help you quit tobacco for good.”
“Over 40 different, evidence-based, techniques will help you get - and stay - smoke free.”
“QuitSure offers 6-day and 6-week programs that removes your desire to smoke”
That is the case ClariLung was built for. Free for 7 days, no credit card.
