This is Schedtrack, a free and open source scheduling software, fully designed and built by me. While the app allows for regular scheduling like everything does, what sets this apart is the ability to customize your schedule if your weekly schedule changes. Shift workers often have irregular schedules meaning they work different days each week and as far as I can see most schedule software leave you to manually enter that; and Schedtrack is designed to accommodate that. This app came out of personal need, and I'm glad the effect its had on others who use it.
