You can never have too many analytics providers. Integrate a few and see which ones you like after months of usage. It’s not a one size fits all category. GA is great for tracking acquisition channels (Just make sure any channels use the UTM links) and basic analytics like browser used, but then we switch over to Amplitude (Which is like Mixpanel) when you want to dive deeper into product behavior (funnel analysis, what features are actually popular vs. dead). Just design your analytics integrations in your app to be modular so you can plug other ones in later such as a generic “traceEvent()“. There are also third party tools like Segment that can do that routing for you, but it’s kind of expensive for what you get and it’s not that hard to add multiple individual analytics SDKs to your apps.
Segment is awesome and lets you enable/disable new services without deploying any changes. To date, Full Story (https://www.fullstory.com/) has been one of our favorite tools becuase you don’t have to predict what events to track, you just see everything! A little big-brothery, but your future users will appreciate you for it
