睡眠日誌 is a lifestyle app developed by NEC Solution Innovators Ltd. It is aimed at helping users improve their sleep habits based on Cognitive Behavioral Therapy for Insomnia (CBT-I), a recognized method for treating insomnia. The app provides three support features that focus on recording and reflecting on daily sleep patterns while equipping users with the correct knowledge about sleep. With the guidance and collaboration of sleep specialists, 睡眠日誌 offers a user-friendly experience that anyone can engage in.

The first support feature, "Recording," allows users to easily track their sleep patterns and visualize them through graphs. Understanding the importance of accurately assessing one's sleep situation to achieve better sleep, the app encourages users to record and review their sleep patterns continuously, enabling them to gain insights into their sleep rhythms.

The second support feature, "Learning," provides users with accurate knowledge about sleep compiled by sleep experts based on medical evidence. By combining the insights gained from recording with the knowledge acquired through learning, users can discover better sleep habits.

The third support feature, "Checking," allows users to assess their sleep state by completing a simple questionnaire and checking their "Fumin Index." This questionnaire has been proven by researchers to be a reliable and valid measure of sleep quality. By regularly checking the Fumin Index every two weeks to a month, users can perceive changes in their sleep state.

Please note that 睡眠日誌 is compatible with iOS 10 and above.
