This app was created for the purpose of collecting data for data analysis, and the total collection period is 8 weeks. The main functions are as follows:

- Record mobile device sensor and activity data
- Track the user's mental health status through a weekly mental health screening tool
- Provides different scales for each week
- In order to accurately measure your condition, you must respond to the survey within 48 hours at the beginning of each week from the participation start date. If you do not respond, you will not be able to participate in the survey in that parking lot (the period has expired)
- Write a daily sleep diary (can be written as of today)
