1) Sleep diary
- You can check your daily sleep efficiency by writing a sleep diary. If you write 7 sleep diaries, you can check the weekly average sleep efficiency, increase or decrease rate of sleep efficiency compared to the previous week, etc. Based on this, Soms recommends a sleep time zone that can improve the patient's sleep efficiency through sleep restriction therapy. Accumulated sleep efficiency data is provided as a sleep efficiency and insomnia statistics graph for one week through the sleep report.

2) Cognitive behavioral therapy
- It is the most recommended treatment for insomnia worldwide, and improves psychological, behavioral, and cognitive factors that persist or worsen insomnia.
- Soms is designed so that you can complete the cognitive behavioral therapy protocol by performing 'Sleep Diary' and 'Today's To-Do' on the home screen every day.

3) Today's progress
- If you complete all the education indicated in 'Sleep diary (written daily)' and 'Today's To-Do', it is confirmed that 1 out of 42 times has been completed.
