There are 10 million smokers in the UK, costing employers £8.7 bn/year and the NHS £5.2 bn/year. Quit Genius is the world's first app to deliver personalised and gamified cognitive behavioural therapy (CBT) to smokers trying to quit. When used in combination with nicotine replacement, Quit Genius augments the success rate of quitters from a baseline of 3% to 35%. We have a B2B model and are working with brands including O2 and Network Rail.
