COCOLOLO is a lifestyle program available on Android developed by WINフロンティア株式会社. This free program allows users to check their emotions and stress levels by placing their fingertips on the smartphone camera for about 30 seconds. The app then detects fluctuations in heartbeats through changes in skin color and analyzes them to display 10 emotional types, including stress, relaxation, fatigue, and concentration. The program's main feature is its AI algorithm, which provides a customized emotional forecast for the day based on WINフロンティア研究所's academic research data and 20 million COCOLOLO measurement records. The program also offers practical advice and mindfulness videos based on users' emotional types and lifestyle, and users can share their emotional certificates with friends in the "cafe space." COCOLOLO is useful for individuals who want to monitor their stress levels and improve their emotional well-being.
