Would you like to examine the changes in the hours you work according to days, weeks, months?

All you have to do is start the timer while it is running, and let the application do the rest.
Record the number of questions you have solved. You can check the time you have worked by examining your progress by days, weeks or even months.
You can set a daily question or time goal and set limits for yourself. You can change the target of the courses you study more.
Review your individual days with column charts. See the distribution of your lessons with the circle graph. We wish you good work...
