CLI that takes in the CSV exported by Firebase Analytics and spits out some stats

Install with gem install firebase-stats

Export the CSV from Firebase analytics (any number of platforms and time periods is fine).

Then run firebase-stats <command> <path to CSV file> <options> (see below for commands and their respective options)

Prints out usage by device model

--platform Filter by platform (ios, android or all)

--friendly Android model numbers are turned into their human readable names (e.g. SM-G991B becomes Samsung Galaxy S21 5G). This is slow as it downloads a file from Google each time, and the parsing speed isn't fantastic.

--limit NUMBER Limits the number of rows output (useful to speed up the --friendly option)

Prints out usage by OS version

--platform Filter by platform (ios, android or all)

--grouped Group by major OS version

--version-sorted Sort by OS version rather than percentage

Prints out number of users of each gender

Prints out percentage of each gender grouped by age
