Ask HN: How to get started with data analysis for a mobile app?

I'm currently working on an iOS app (https://www.gurgee.com/) and have reached a point where I feel I'm flying blind.

I use Google Analytics for the website, Firebase analytics for the app, and Apple's App analytics for the App Store data.

Is there software that can combine all this data into one place?

I hear Geckoboard and Klipfolio are good options, but I'd rather learn from someone who has experience in this topic.
