V2.0.2

August 20, 2026

Quick Search, rebuilt • Ask for what you want in plain words — "fluorite and quartz from Peru", "Zeolites from India" — and Smart Search (Beta) does the rest. • "Narrow results" turns your results into tappable mineral and locality filters, no re-typing. • "Did you mean…" helps when a place name is ambiguous, plus related-search suggestions when nothing matches. • Price and currency filters on live listings are now free for everyone (archive stays premium). Browsing improvements • Available / Archived specimen toggles on mineral and locality pages. • Auctions, Localities and Sellers lists remember your place when you go back. • Seller videos now play on item pages. • Refreshed gem and mineral icons throughout, more compact Live Feed cards, and clearer AVAILABLE / ARCHIVE / ENDED badges. • New spin coach on the home wheel so the menu is easier to discover. Fixes and polish • Faster, more reliable startup. • Pull down to expand the header on search and browse screens. • Fewer rate-limit stalls when scrolling the live feed quickly. • Filter badges and "clear all" now behave the same across every list. • Security and dependency updates.

Needs photos

This app would be good for geologists as a reminder of things they already probably know. But for newbies trying to about minerals for the first time it really needs a photo of the mineral.

Almost

I really enjoy this app! Give the complete description of the minerals that I’m searching for, and ones that I was unaware of to begin with. The only issue that I have with it is that every time I choose a mineral to look up and back out of, I can’t scroll up or down until I click the search bar and cancel the search. Fix this little issue and I’ll change it from 4 stars to 5. Otherwise, this is an amazing app!
