Cho-Kinen | Quit Smoking With Haita

Quitting smoking:
less struggle, more staying power.

A simple, easy-to-stick-with quit-smoking tracker that keeps you company with Haita (肺太), a friendly lung character. Your smoke-free time, the cigarettes you didn’t smoke and the money you saved add up automatically. No sign-up needed. Since version 1.4.0, you can also grow “Haita’s room” with the money you save.

Free (all core features are free; offers in-app purchases) · App language: Japanese

NEW · 1.4.0 / 1.5.0

The money you save grows Haita’s room.

Ten times the money you save by not smoking becomes “Haita’s money”, which you can spend in Haita’s room. The longer you keep going, the livelier the room gets — a little bonus for staying smoke-free.
