    I’ve been 2 months smoke free now, and while you need motivation yourself this app really helps you keep it. Wish it had been available years ago !

    spurs 81-82

    This app is genius. I've found it pretty easy to quit, no nicotine patches just willpower & the right frame of mind. Download it & quit - it's great being a non smoker after 20 years.

    Definitely the best stop smoking app. The diary reminders are a stroke of genius. I've already recommended it to others.

    One of main motivators of quitting by will power alone for me is the health progress section of this app. Lots of missions & reflection for yourself plus opportunity to contribute to research if you wish. Best app I've used.

Why are we charging?

A version of Smoke Free will always be free to use. This version will be at least as good as the other free apps available. And we’ll keep improving it.

We’ll use the free app to learn what techniques help people stop smoking. You don’t have to take part in these experiments and can use the app fully and for free if you opt-out. If you take part, fantastic, that will make our evidence stronger and we'll publish this evidence so others can benefit. This means that just by using the app you’ll be helping more people quit smoking.

When we find what works we’ll put that into a version of the app that people can pay for if they want. The money we raise will go into improving Smoke Free and creating other apps that help people change their behaviour.

You don’t have to pay for Smoke Free. Our free app will contain the same features the other free apps do, plus it will be beautifully designed and a joy to use. But if you need more help you can pay a small sum for something that we can say with confidence is effective. And you’ll be helping us build the best damn behaviour change company in the world.

Do I have to take part in the experiment to use the app?

No, all the app's features will work regardless whether you participate in the experiment or not. However, it'd be great if you could complete the daily smoking diary, as the information you give about your cravings might help the quitters who follow be more successful. Plus other users have said that they found keeping a diary helped.

I use nicotine replacement and/or an e-cigarette, can I take part?

You can. I'm not testing whether the app helps people stop smoking on its own but rather, whether aspects of it work better than others. I also ask about any NRT you may be using in the questionnaire you'll see when you register and at one month and three months after your quit date. So using NRT won't affect the experiment at all.

Can I change details about my smoking?

Just go to:

 Help >> App Settings >>  Change smoking data
 Settings >>  Smoking data

You'll be able to change the cost of your cigarettes, how many you smoke each day; things like that

Can I change my quit date?

Easily, if you go to:

 Help >> App Settings >> Change quit date
 Settings >> Change quit date

This will reset the amount of time you’ve been smoke free, the amount of money you’ve saved, how many cigarettes you haven’t smoked and any badges you may have earned.

How do I turn off or change the time of the reminders?

The reminders can be found in the Help tab of the app. You can stop them happening entirely, or change when they appear.

 Help >> App settings >> Turn of notifications

How do I change the currency settings?

  [phone] Settings >> General >> Language & Region >> Region 
 [app] Settings >> Smoking data >> What's your localization/region?

What else can I change?

There's a good few options in the Help tab. Have a play around, you probably won't break anything.

How do I opt out completely?

If you go to:

 Help >> App settings  >> Opt out of the experiment
 Help >> Opt out

An email will be sent with all the details I need to ensure your information is deleted from the write up.
