You can record the date and time you used your phone and check it on a graph. You can see what time you fell asleep while touching your phone and how much you used it in a day. There is also a heat-map display that shows which days of the week and times of the day you used your phone the most.

- The 60 button toggles between a relative bar graph and an absolute bar graph for 60 minutes.
- The number of days of use is counted when the phone is put to sleep at least once during the day, and is not counted on days when the phone is not used.
- No special permissions are required for the application. The app only records the time when it sleeps and wakes up, and does not add to the load.
- The app is designed to prove that you are not operating your phone if a police officer suspects you are operating your phone while driving a car. For more information, please visit https://sites.google.com/view/asilaysleepinglogdata/
