The record
Records that hold up to scrutiny.
Bought at a show, traded with a friend, inherited, or found by hand — every specimen gets the same collector-grade record. Taxonomy looked up against the Paleobiology Database, the full Era→Period→Epoch→Age hierarchy, partial dates for old acquisitions, and the money side kept straight.
- Acquisition method, source & dates — just fields, not steps
- Price paid & estimated value, 29 currencies
- Per-category fields: Mohs to metamorphic grade
- Disposition history: sold, traded, gifted
Organize
Labels worthy of a museum drawer.
The Label Creator turns records into print-ready PDF label sheets — Modern or Classic templates, three sizes, A4 or US Letter, previewed in-app before printing. And the vault is never a lock-in: CSV import with review-before-save, export with images as ZIP, anytime.
- Modern & Classic templates · 8×6, 7×5.25, 6×4.5 cm
- Batch by search, period, country, or tag
- Storage location & inventory IDs on every record
- CSV v1.2 in/out · ZIP export with photos
Understand
Your collection, quantified.
The Stats dashboard mirrors what's in the vault: value and spend side by side, the category mix, your crown jewel, geological time coverage, a world map of where it all comes from, and your collecting activity over the years.
- Est. value vs total spent, average per piece
- Category mix & geological time coverage
- Find map, country breakdown, activity streaks
Want lists
Know exactly what you're after.
Keep a structured list for every hunt — taxon, locality, condition, size, and what you're willing to pay. When a piece turns up at a show or in a trade, mark it found, record what you paid, and link it straight to its new specimen record.
- Budgets per item, budgeted vs spent per list
- Found → linked to the record, milestones as the list fills
- Share a list as a simple web link when it helps — no app needed to view
Field days
And when you do go digging…
Plenty of great collections never touch dirt — everything above works without this. But when you do head out, Localities remembers each site the way you would want to: the geology down to the bed, how to get in, and what the tide was doing. Log a visit and the day writes itself — weather, wind, tide — and any find is one tap from becoming a full record with its provenance already filled in.
- Site geology: formation, member, bed, lithology
- Visits with auto weather, tide & conditions
- Finds logged per visit → promoted to specimens
