About
A desktop lookup tool for Roco Kingdom players that shows which pets match an egg's size and weight within an egg group. Its data on 578 pets is generated from rocom-wiki-data and built into the app. The interface is a web frontend running in MyGo's WebView, with lookups handled in Go; builds are made for Windows and macOS, and the macOS builds are not notarized.
