The app, which has a high average user rating of 4.7 out of 5, went on sale for the first time this week in more than 1,400 Boots stores across the UK and online.
The app follows National Institute for Health and Care Excellence (NICE) guidance on quitting smoking, with users encouraged to monitor their progress, from improving their health to saving money.
An exciting new feature of the app is expert-led stop smoking clinics held on the app twice-daily Monday to Friday, with experts trained by the world-renowned National Centre for Smoking Cessation and Training guiding users through challenges.
Almost half of all adults in the UK smoked in 1974, a figure which has since dropped to 15 per cent. The government now wants to make smoking tobacco obsolete in England by 2030.
Smoke Free Plus was supported by DigitalHealth.London's Accelerator Programme, and its programme director, Sara Nelson, said, "We are delighted to see the company grow and have the potential to make a national impact on the millions of people who want to give up smoking this New Year."
