Quit21Quit21 vs QuitNow: Quit smoking for good
By Yevhenii, who makes Quit21 · Checked 31 Oct 2026A side-by-side look at Quit21 and QuitNow: Quit smoking for good, an app by Fewlaps of Barcelona, using only what both apps, their developers and a published review say publicly. Checked on 31 October 2026. I make Quit21, so read it with that in mind. Where QuitNow is stronger, this page says so.
Side by side
| Feature | Quit21 | QuitNow: Quit smoking for good |
|---|---|---|
| Platforms | Android and iPhone | Android and iPhone, with a Wear OS watch app and an Apple Watch app. |
| Price | Free, with a small banner ad | Free, with ads, and in-app purchases for a Pro upgrade. The App Store lists Pro prices from $2.99 to $34.99 without saying which price is which plan. |
| Popularity | New. On Google Play since October 2026, so few ratings. | Over 5 million downloads on Google Play (4.6 from about 69,000 ratings) and 4.7 from about 14,000 ratings on the App Store. Its site claims over 10 million downloads. |
| What you can quit | Cigarettes, heated tobacco and vaping, each with its own arithmetic | Smoking. Its listings and site speak only of cigarettes; vaping is not mentioned. |
| Daily guidance | A text for every stage: 20 minutes, 8 hours, days 1 to 30, 3 months, 9 months and 1 year. Written separately for smoking and vaping, each with named sources. | A step-by-step course presented like an in-app book, and health indicators based on WHO data that the developer updates when the WHO updates its data. |
| Community and experts | None. The app is a private, quiet space. | A chat for people who have quit, and monthly live Q&A sessions with a smoking-cessation expert. |
| AI assistant | None | QuitNow AI, an assistant for quitting questions based on the app's course and WHO data. |
| After a slip | A slip subtracts only what was smoked. Totals, medals and pages already read are kept, and the day count restarts. | Not described on its listings. |
| Help with a craving | SOS: your own reasons and a one-minute paced-breathing exercise, then a note of what set it off. | Not described on its Google Play listing. A 2022 pharmacist's review of an earlier version mentions a calm breath assistant in the paid upgrade. |
| Diary and triggers | A daily diary, a log of triggers and a view of when cravings come. | Not described on its listings. |
| Money, goals and medals | Money saved, cigarettes not smoked, a piggy bank for something you are saving towards, and 29 medals. | Money saved, cigarettes avoided, life regained, and 80 milestones. |
| Widget | Home-screen widget | Widgets on iPhone, and tiles on the watch. |
| Languages | English and Ukrainian | English and 27 more on the App Store. |
| Account | None | Not stated on its listings. Its site links to a sign-up flow and a subscription-status page, and the chat connects you with other users. |
| Your data | Stays on the phone and is never sent to the developer. The banner ad is served by Google AdMob, which collects device information such as the advertising ID and an approximate location. You can delete everything in Settings. | As declared by the developer. Google Play: no data shared with third parties; personal info, messages and four other types may be collected; users can request deletion. App Store: location, identifiers, usage data and diagnostics are listed as used to track you, for purposes that include third-party advertising and analytics. The two declarations differ, so read both. |
| Outside review | None. Quit21 is not a medical device and its texts have not had a medical review. | Rated 4 out of 5 by a community pharmacist on Healthify NZ in November 2022, reviewing version 6.42.2. The app has changed a lot since. |
Where QuitNow is stronger
- It has a community. If talking to other people who have quit helps you, QuitNow has a chat for that and Quit21 does not.
- It offers monthly live sessions with a smoking-cessation expert and a structured quit course.
- It has a much broader feature set: 80 milestones, an AI assistant, book recommendations and watch apps.
- It is available in 28 languages and has over 5 million downloads on Google Play. Quit21 is new, in two languages, and has very few ratings.
- A community pharmacist's review is published on Healthify NZ, although it covers a 2022 version.
Where Quit21 is different
- It covers vaping and heated tobacco as well as cigarettes, and never converts a vape into an invented "cigarette equivalent".
- It explains the day. Each morning there is a page about what is happening in your body, what to expect and one thing to try, with sources named at the bottom.
- A slip subtracts only what was smoked, and the totals you earned stay.
- There is no community, no chat and no account. Your diary, slips and reasons stay on the phone and are never passed to the advertising code.
- It is deliberately small: a few screens, no feed and nothing to subscribe to at the moment.
Which one to choose
- Choose QuitNow if you want a community and an expert to talk to, a guided course, or an app on your watch, and you are happy with an account and a paid upgrade.
- Choose Quit21 if you are quitting a vape or heated tobacco, you want each day explained rather than only counted, or you want an app that needs no account and keeps your data on the phone.
- Use both if you want the community in QuitNow and a private daily explanation in Quit21. They do not conflict.
