Kaiho is an independent French company developing a mobile app to help people stop smoking by understanding addiction rather than relying on willpower alone. Founded by Vincent Pellaumail, a smoking-cessation coach, and Arthur Chambriard, a mobile developer, the company brings coaching experience and product design together in a calm, supportive approach. Its method addresses the physical, behavioral, and psychological dimensions of tobacco dependence.

The Kaiho app is built around Pellaumail’s seven-key method and offers a step-by-step preparation program, daily guidance, exercises for managing cravings, and progress tracking. It also includes support for dealing with relapse without erasing the user’s progress. Kaiho avoids guilt-based messages, streaks, and pressure, aiming instead to give users clear tools and steady support throughout the process. The app is available for iOS and Android through the App Store and Google Play. Kaiho’s approach is grounded in Pellaumail’s years of coaching and work on addiction psychology, with the company emphasizing thoughtful development and respect for the people using its product.
