User behaviour analytics with React Native and Expo

I am currently in the testing phase of my application and have been giving it out to testers.

Is there some kind of user behaviour analytics lib that I can use to get reports on things such as user actions, how many times the app has been opened, how long spent on app etc.

My app does not currenly have any kind of Auth or user login so all my users are anonymous. I hope this does not get in the way of this type of functionality.

Thanks!
