What do people use for analytics?

I was just wondering what people are using for collecting analytics in their ionic 2+ apps?

From what I can tell Google Analytics is no longer possible as it’s transitioned to Firebase for mobile apps. I’ve tried the firebase analytics native plugin, but that is in beta and fails when I try to install the plugin on a brand new ionic app. I noticed Flurry Analytics from Yahoo, but haven’t tried that yet.

I use MixPanel. There is a plugin for ionic 2 and pretty decent restful APIs if need a customized approach. Also tried Google Analytics - pretty good as well, but I am very happy with MixPanel.
