幸福橘之森 (Happy Orange Forest) is an Android application developed by Lucidity Media Co. Ltd., available for free in the Education & Reference category. The app aims to provide various mental courses and activities to promote a balanced and fulfilling lifestyle. It focuses on nurturing positive interpersonal relationships through timely reminders, fostering connections based on care and love, and offering guidance towards happiness during moments of confusion or loss.

To accommodate the busy lives of modern individuals, Happy Orange Forest breaks through time constraints by offering concise, visually engaging courses and gamified interfaces. The initial launch includes three main applications: Happiness Diary, Mental Courses, and Happiness Oracle. These applications are designed to provide mental healing, enhance interpersonal relationships, and facilitate personal growth.

The app offers a unique approach to mental well-being, combining online and offline activities, and introducing users to the concept of "Happiness Economy," where reaching certain levels of mental growth allows users to earn virtual "orange coins" for various benefits and activities within the app.
