Quit21 vs Quit Tracker: Stop Smoking

A side-by-side look at Quit21 and Quit Tracker: Stop Smoking, an Android app by despDev, using only what both apps and their developers say publicly. Checked on 31 October 2026. I make Quit21, so read it with that in mind. Where Quit Tracker is stronger, this page says so.

In shortQuit Tracker: Stop Smoking is a free, ad-supported Android tracker with over 5 million downloads and a 4.8 rating on Google Play. It counts smoke-free time and money saved, shows a body-recovery timeline, and adds a craving game, a biometric lock, backup and export. It is not on iPhone yet. Quit21 is a newer free app for Android and iPhone that opens a sourced text for each day of quitting, covers cigarettes, heated tobacco and vaping, keeps everything on the phone and has no account. Pick Quit Tracker for a long-established tracker with extras. Pick Quit21 for an explanation of each day, for vaping, or if you use an iPhone.

The listing does not say which of these come from advertising.
Outside reviewNone. Quit21 is not a medical device and its texts have not had a medical review.Rated 4 out of 5 by a pharmacist on Healthify NZ (February 2026, version 2.31): well suited to people already committed to quitting, with limited behavioural content and no professional support.
