Smoke Free - Quit Smoking Now

This is the stop smoking app that science built. Over 20 different, evidence-based, techniques to help you become - and stay - smoke free. See how much money you've saved, how many cigarettes you've not smoked, how long you’ve been smoke free, how much life you've regained and how your health is improving.

All this is free to use and entirely free of ads. If you need extra help giving up smoking our missions could be just what you need, as they’ve been proven to double your chances of quitting. No other app can promise you this.

We proved the missions worked by performing a rigorous scientific experiment. As far as we know, this is the first ever randomised control trial run entirely within an app. Its success means we want to run many more and our goal is to constantly make our app more effective

This is all entirely voluntary and you can download the app without taking part in the experiment. Your data will be kept anonymous and you can delete it at any time. But we really hope you do take part because everyone who does will help the quitters who follow. So do yourself a favour by quitting smoking. And do your fellow smokers a favour by helping them understand how it’s done.
