synchronize with the IOS reminder app, so the calendar would be perfect. in this way the calendar would be the best in the store, if not of little use this calendar for the day to day.

Display or sync reminders of iOS devices like Fantastical does. it will save using Calendar and Reminders separately, and also boost the market of one calendar. 

Draw backs-

Also a very few updates has been available. would be nice if it has updates every 8 to 10 months so that it is current to the current needs.   the syncing time from my different calendars into one calendar is approximately 10-15 seconds. 

Along the same line it’d be great if there’s an option for the widget to show the next 4 weeks starting from the current week (instead of showing by fixed months).

While your monthly calendar is very nice, it would be of assistance to have the choice to wrap the text of an event.

Can you add the ability to set multiple alarms for reminders and appointments? The Google calendar has that feature, and it really helps. For example, I might want to give myself a 1-2 day advance warning about an event and another an hour before it. That’s a valuable feature. For some events, I set multiple reminders.

Descript Could you toggle calendar view with iOS reminders e.g. as in calendar 366
