Kwit, it’s the story of a developer who wanted to quit



Geoffrey made an important decision: "I am quitting smoking!" He was looking for an app to help him achieve this, but the few apps available failed to meet his needs, so he created one of his own.


Kwit was created and became the first game-like application using a kindly approach to make quitting smoking not only easy but also fun.


Geoffrey welcomes two friends to be part of its adventure to further develop the application, which by now is helping increasing amounts of former smokers to stay smoke-free.


Today, Kwit is a team of about fifteen people and experts in different fields. Addiction researchers, academics, and health care professionals support it as well.
