CleanAir is a free quit smoking app and smoke-free tracker with gentle support, progress tracking, and a clear quit smoking timeline. Unlike other apps in this space it is completely free, and it provides a "panic button" for instant support when cravings are intense. It celebrates milestones to give that hit of dopamine that smoking used to give.
I read a study which said that people are "up to 3 times more likely" to quit smoking with an app - and this makes total sense to me. An app gives regular hits of dopamine. Give up for 24 hours? Get a celebration, a milestone, a little certificate. It can become a source of reward, identity and achievement which isn't just about "white knuckling it".
I made my app to be completely free and accessible to all.
