Vincent has coached smokers for years. Arthur has built mobile apps for just as long. They didn't know each other, but they shared the same observation: almost every quit-smoking app out there is bad.
They shame you when you slip. They bet on willpower alone. Most have no real method behind them: just a counter, a streak that resets at the first stumble, and a moralizing tone that turns quitting into punishment.
In early 2026, Vincent was looking for a developer who could translate his method into a real app, without betraying it. They found each other. Kaiho was born from a simple conviction: you don't quit smoking through willpower, you quit by understanding. No score, no moral lectures. A method, tools, calm.
