Every shell you have, and the beach it came from.
Concho keeps your shell collection in one place: each shell's photos, its species, where and how it was taken and who found it, its size and grade, and what it's worth. It keeps your collecting spots and shelling trips, the checklists you're working through, and what you want and have to trade, and it lets you show off your collection with a link.

🐚 The Conchopedia
A shared reference of 711 shells of the world: type a common or scientific name and the other fills in, with its group. Learn how to know each one, where it lives, how rare it is, and what protects it.
🥾 Spots and shelling trips
Keep the places you collect, with their GPS, directions, and access notes encrypted. Plan a trip with a packing list, add your finds straight from it, and see everything a spot has given you.
✅ Checklists and wants
A shell from every group, the classic cowries, Florida's beach shells, the famous rarities, or every cone in the Conchopedia: fill each spot from your shells, and put what's missing on your want list for the next show.
🖼️ Galleries and trading
Share your collection, or a trade list, with a link or a QR code on your show table. You choose how much of each locality to show; visitors can message you without seeing your email.
🏷️ Labels and permits
Print classic shell labels with locality, date, and catalogue number, and a QR code. Protected species are flagged, with their permits kept encrypted, and cone snails come with a warning.
🔐 Private, and yours
Share the whole collection with family or a club friend, to look or to help keep it. Exact spots, where specimens are kept, and every photo and paper are encrypted. Reports for insurance, a theft, and an estate.
Values are your own estimates, and the Conchopedia's sizes are typical ones: shells vary. Concho isn't an appraisal, or legal advice about where you may collect: check each place's rules (many ban taking live shells), and never pick up a live cone snail.
