I've been collecting minerals since I was 14, when I found a smoky quartz on a hike and decided it was mine now. Twelve years later I have a few hundred specimens, strong opinions about fluorite (beautiful, fragile, do not bulk-ship via USPS), and a new appreciation for wolframite (survives everything, looks like it could fight you).
I built this app because I went home after two years and realized I couldn't identify my own collection. Not a great look for someone with hundreds of specimens. I'd never recorded a single locality. So I did what any CS student who can't find a job would do — I built the app I wished existed, and then spent way more time on it than planned. Want to build with me?
