Freezes and closes – Shift Change Review

Not working. When I tap on the 5th it highlights the 4th or when I tap on 19th, it highlights the 18th. Same for every date I try. And I can't drag a day to select multiple days like the app describes. And sometimes it suddenly freezes and closes by itself. It's useless and they need to fix it otherwise it would have been a beautiful and useful app
