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
