It would be nice to be able to put a start time and use the all day function because I have a "start time" to my "all day" event.

The option to improve security by having to do Face ID or enter passcode when opening calendar

Add an off-line on-premises Calendars (and tasks-lists on One-task)

This would give more screen area for the appointments!

This would give me more screen real estate for the appointments.

Multiday events without start/end time (whole-day events) are presented in the top area. There should be an option to get the same behavior for multiday events with start/end time.

Please add the option "public / private" in the appointment view

This calendar has deleted past events. I don’t know how to get them back as I have redownloaded all of the same calendars 

Can you share your calendar so me and my husband can share it together? He adds his and I add mine on separate devices?

The description pretty much says it all. I have several calendars successfully syncing to One Calendar for Android from different sources, two of them are from Office 365. All the appointments sync correctly except any recurring appointments don't sync to One Calendar.

It's not possible to change recurring appointments

Hi there, is there a way to create One Calendar to personalize the background with my own favorite photos from my photo albums? Also, can you please add more colors to the color schemes? For instance, Periwinkle, Olive Green, Ocean Green, Ocean Blue, Soft Powder Blue, Faint Pink, Light Coral, etc. This will help with personalized appearance of Holidays as well as personal events added to the calendar. Also, better colors for numbers on calendar. Some colors cannot be seen so I don’t use them. Thanks!

Please make this app sync with Calendly

I have some calendars shared with me by others at work that have somewhat convoluted names. I would love the ability to rename these calendars internally in OneCalendar.

The bigger version of this issue is with web calendars. I subscribe to 4 or 5 of these. They import to OneCalendar labelled as a webs calendar with generic name "Calendar". That makes it very difficult to keep the web calendars apart from one another. Would love to be able to rename them for clarity
