睡眠日誌 (Sleep Diary) is an app that aims to help you improve your sleep habits by providing support based on Cognitive Behavioral Therapy for Insomnia (CBT-I), a recognized treatment for insomnia. Developed in collaboration with sleep experts, this app offers a user-friendly approach by focusing on three key support features, while helping you gain the correct knowledge about sleep.

The first support feature, "Record," allows you to easily track your daily sleep patterns and visualize them through graphs. Understanding your sleep patterns is crucial for achieving better sleep. By consistently recording and reviewing your sleep data, you can gain insights into your sleep rhythm and make necessary adjustments.

The second support feature, "Learn," provides scientifically-backed information about sleep as "tips for better sleep." By combining the insights gained from recording your sleep patterns with the knowledge acquired through the app, you can discover and adopt healthier sleep habits.

The third support feature, "Check," enables you to assess your sleep state by answering a simple questionnaire and checking your "Fumin Index." This questionnaire has been proven by researchers to be a reliable and valid measure of sleep quality. Regularly checking your sleep state using this feature allows you to perceive changes in your sleep condition over time.

Please note that "睡眠日誌" is compatible with Android devices running on OS 5.0 or above. However, there have been reports of issues with devices running on Android OS 6.x or below, where the screen does not switch after answering the initial questionnaire. If this issue occurs, simply close the app from the list of running apps and restart it. Additionally, it is advised to perform data transfer from the app before upgrading the Android OS to prevent data loss.
