How I Slept: Sleep Diary

How I Slept is a sleep diary designed by a sleep expert, to meet the needs of patients who are struggling with their sleep. It is free to use, and no account or personal information is required to track your sleep. Fill out your diary in under 2 minutes, and visualize your sleep patterns in charts and summaries that can provide you with insight into your sleep patterns over time, which can easily be shared with your sleep and medical team. Sleep diaries are a core part of treatment for insomnia, circadian rhythm disorders, and improving overall sleep health. Understanding the pattern of your sleep over time is important for a sleep clinician, before they recommend making any changes. This app was developed by Dr. Eric Zhou, a sleep expert with over 15 years of clinical experience helping patients sleep better. It was sometimes challenging for patients to track their sleep using a pen and paper-based sleep diary, so he created this app to make the process easier. Based on your inputted information, the app will provide calculations for important sleep health metrics, such as how long you slept and your sleep efficiency, and generate charts and visual summaries that give you an understanding of how your sleep looks over time. Importantly, this app was designed with your privacy in mind. The sleep data you enter stays on your device, and is not uploaded to the cloud. Without your request, none of your data will be shared with anyone. No account registration is needed. This app is a diary for keeping track of your sleep. It does not diagnose or treat any condition, and it does not replace advice from your doctor. Check with your doctor or a sleep specialist before making any decisions about your health, your sleep or your medications.
