Metrics in the game, for a beginner, what to choose?

Question

Game development

Good day)
Perhaps there have already been such questions, but I googled something and did not find the right one.
It took "urgent" to add analytics to your mini toys. As far as possible, collect everything that is possible.
But at least I want to collect standard parameters such as new unique users, re-installs from old users, time in the game for various sections, and most importantly, the time of one session of the game, and not starting / closing the game. and specifically the time spent on a single game and the result.
The analytics itself should have a clear interface (for example, I don’t like the interface of the analytics unit, but Google’s one is quite decent) and the ability to export all the collected analytics, because in another month I plan to write my solution for analytics, since I can’t find the right service for 100% .
What service can you recommend?
Once again the list of requirements:

• Easy integration with Unity
  
• Collection of analytics on users, new, returns/re-installs, traffic sources
  
• Custom events for sending session points, game session time.
  
• Ideally, the ability to collect different time frames is already implemented in the service\plugin itself.
  
• Ability to bind events to each other. Perhaps this is just done on the server side by the time of receipt)
  
• Export all data
  
• Clear\nice interface
  

Answer 1

gameanalytics, amplitude, crashlytics, dev-2-dev. Choose. Or, better, integrate some (or all). More data is better.
is there nothing to do? There are ready-made solutions - use them. The maximum is the processing of csv, which will be unloaded from the analytics. And writing your own is a lot of hemorrhoids.
