I have been using OneCalendar for about a year now. I'm looking for a calendar that retains my records for 10-20 years so I can enter historic events and have a convenient way to search for them later on. Can you tell me how long OneCalendar will keep my records? Thank you.

Major flaw with subscribed calendars and flaw with reminders

2022-04-28

by Astrosabby

Updating to add a major flaw I’ve come across. Subscribed .ics calendars don’t show double-booked slots. It will only show one of the items in that time slot. Complete killer for me. I am often double booked and have to make a game time decision which one to go to. I’ve missed important meetings because of this issue.

Already noted: If you can’t add a reminder to an imported web cal event (or even just import the reminder from the original event), then this app become pretty useless. For google and iCloud calendars, it’s ok, but the reminders still need work.

Wrong day of the month on the Front page

by What Day Is It Today!

It’s absolutely ridiculous that the front page of the calendar only shows the number one!!! One of the major points of a calendar on an iPhone is it when you wake up in the morning or at any time you can just look at the front page and you see what day it is. Instead, you have to go into the calendar to find out what day it is. Well that is extremely annoying. Therefore I will be looking for another calendar. How could anybody come up with such a ridiculous idea. It is absolutely outrageous.

What Happened?

2022-05-12

by LISCTR

This is my favorite of all the calendar apps available for iPhone, but something changed in the last few months and now you can no longer “delete this and future” events. Why? Why can I only delete everything past and future or have to go through the future and delete one at a time? Life changes. Reoccurring events sometimes have to be deleted for the future but that doesn’t mean I want the past deleted as well. Please fix this!!!!! Thank you.
