The week view looks nice, but overall the app lacks a lot of functionality. Would like to see a month view like Week Calendars mini-month view. Would like to see a year view. I think the Month calendar on the week and day view is good for reference but is too small as a month view replacement. The swipe to jump to the next month feels awkward to me. I could not find a way to change color used to identify different calendars. Hopefully, the developer will add more functionality with future upgrades. Good as a start, but will not replace my go-to calendar which is Week Calendar.
