Good. But could be better.

Does what is says. Seems to be the only app thats actually like a day planner. I would like to be able to set the default calendar specifically to this app and not have to change the calendar default as well. I would be happier with my purchase if it were less like a different format of the built in calendar, and more like a stand alone checklist, at least optionally. I would like to be able to check off completed tasks.
Buggy when rescheduling events. Keeps booking all day events to span two days.
Change these issues and I would give it 5 stars.
