App: Focus, Former Stand Reminder
Developer: 鑫 肇
Genres: Productivity, Lifestyle

Focus is committed to improving your concentration at the specified time. And after the specified time is completed, remind you to stand up and move your body.

### How It Works

Focus on detecting whether the user has a keyboard or mouse or other operations within a period of time through the system service to determine whether the user is busy in front of the computer. The default monitoring time is 2 minutes and 45 minutes. For example:

When the user starts to use the computer, Focus begins to be detected. If the user does not have any mouse or keyboard operation for 2 consecutive minutes, it is considered that the computer is not being used. The cumulative time is zero. If the user keeps using it, at the 45-minute Focus will remind the user to stand up and move. If the period is zero, and then the user comes back, Focus will automatically re-accumulate the time after it is detected.

During the operation, Focus will detect the application you are currently using and accumulate the usage time. After that, the proportion of your use of the app in these 45 minutes will be calculated. At the same time, each application has its own category type. Focus will also count the time of category type during the operation period, and calculate the proportion of the time used for the highest category type as your current concentration.

Simply put, in these 45 minutes, the longer you use the application you work with, the more focused you will be. If you use other unrelated apps during the second period, your concentration will decrease. Therefore, you can improve your work efficiency by improving your concentration.
