I can not use 2 different calendar apps without them syncing

[Chris Stone2]

I want to use 1 calendar app showing just my personal calendar dates and info. I’d like to use a second calendar app to show just info from works calendar. Both are gmail accounts. When I have both accounts on my android phone, both apps completely sync. If I uncheck boxes for one account on one app, it automatically unchecked on the other app.
Are there any apps that will only display info from one gmail account?
