Good calendar for iPhone

I tested many calendars. Calvetica is much better than others (Agenda Calendar). But not the best for me.

Strong sides are: short time necessary to add new event, option where I can set many reminders many views list, agenda, week. Also great support. Good job here.

But bad side are crashes. Many time I get error during add alert from agenda view. Alert is marked as saved and after few seconds unmarked?! Also changes from all day event to specified time event make often crash. Many times my default calendar is unchecked from some reason and to check my terms I need one more time select them in settings.

I am/was a big fun but now I testing Calendars+ by Readdle. The philosophy there is different but I get no crashes.
