So, I've been trying a bunch of different calendar apps, and I've noticed that every one I've tried wants to pull data directly from my ios Calendar app, as opposed to linking directly to an account (like most mail apps do, they use your account creds to log directly into your exchange/gmail/etc). Now, I want to keep my work and personal calendars completely separate. I add my personal calendars to my phone by syncing my ios cal app with my gmail calendars. However, I'm looking for an app that will let me sync my exchange calendar with it directly, so I don't have to add it to my default calendar app. I'd like to keep those two ecosystems completely seperate (which I'm able to do for emails). Anyone know a calendar app that takes your credentials and syncs directly with exchange instead of needing to go through default calendar app? Or, is this another "by design" system of forcing integration similar to how most browsers are really running safari in the background? Any help is much appreciated, and thanks in advance.
