Overlap takes a set of subjects, each containing a set of groups, and finds all the resulting schedules that do not have overlapping times.

Only add subjects and fill them with the corresponding groups. The app forms all the possible combinations and discards the ones that have overlapping times. After the analysis is completed, the final result is the combinations that do not contain any overlap.

The app is aimed at students who are setting a school schedule, but it is universal enough to be used by anyone who needs to find overlapping times in any kind of schedule.
