Smoke Free

The stop smoking app

that science built

Smoke Free – in numbers

• 500,000 users in less than 2 years

• 1.5 million diary entries

• More than 1 million user sessions and 9 million screen views last month

• 1,839 five star reviews (79 one and two star)

The problem

• Smoking is the leading cause of preventable illness and death in the UK

• Smoking will kill 500m people alive today (Prochaska et al., 1993)

• Most people who smoke want to stop (e.g. Robinson et al., 2009)

• But the vast majority of quit attempts fail (e.g. West et al. 2007)

• Therefore, the key task is to help people maintain their quit
