Why: I needed a quick way to look at statistics without having to resort to something heavy such as Python + its statistics module or Excel.

Disclaimer: Vibe-coded by Gemini 2.5 Pro and Opus 4.5 but also validated through unit tests and independent verification[2].

Install: Homebrew[3] or GoReleaser built binaries[4].
