Impossible interface on iPad – Calendars 5 by Readdle Review

I was setting an appointment, and it took far longer than it should have to figure out how to change the appointment duration. Too many clicks into specialized screens. And then, the app decided that I meant an appointment from 2 PM until 3 AM on the following day, and it took me a good 30 seconds to figure out how to change the duration to just one hour on the one day. Needs work.
