Checks it as done and then unchecks sometime at night with previous due date. 27 Oct 2018: After hearing back from the author, giving it another shot. Put two repeating tasks on it. See how it goes. 27 Oct 2018: This app didn't work as well for me. It would regularly uncheck tasks I'd completed or check tasks I'd not completed. The repeating task function didn't work well either.
