This application is intended for maintaining a log of visits, making a list of visitors, as well as for analyzing the total time spent by a visitor, taking into account a certain period. This is a mini time tracking system. In addition, this application can be used not only for the administration of visits, but also for your own calculation of the time spent on any actions carried out during the day. For example, if you use your daily schedule instead of the list of visitors, then after a day, week, month or year, you can find out the number of hours spent on a particular action.
