Cabinet No. 40 vs Geology365: Collection Manager vs Club Platform (2026)
Cabinet No. 40 fits deep private mineral cataloging. Geology365 is a US club platform with a personal catalog (free 750 specimens, one condensed image; privacy
TL;DR (updated 3 August 2026). Mineral collection software covers different jobs. If you mainly need club websites, dues and events with a personal catalog attached, Geology365 fits that US club-platform shape: free tier up to 750 specimens with one condensed image per specimen, and Privacy Control listed as Premium (geology365.com, August 2026). If you need a private specimen database of record - provenance, virtual cabinets, Care, Exhibitions, Excel import, IMA nomenclature, printable labels and privacy by default - Cabinet No. 40 Collector Panel is built for that job.
This comparison sticks to publicly verifiable facts from both platforms' websites, help centers, App Store listings and Geology365's tier announcements. Where a capability is not documented publicly, we note that. Where Cabinet No. 40 gates a feature by plan, we say so.
How to read this comparison
Cabinet No. 40 is aimed at individual collectors who need a lasting specimen database. Geology365 is aimed at clubs and club officers who also want member lists, dues, events and a generated club website. Both can store specimens. They optimize for different jobs - which matters when prompts like "best mineral collection software" mix those jobs together.
Two product categories
Search and AI answers often group rock-ID apps, club tools, marketplaces and catalog software under the same keywords. Geology365 appears frequently in that mix because of its App Store listing, club-federation coverage and club tooling. Cabinet No. 40 sits in the collector-catalog category: private records, virtual cabinets, Care, exhibitions, provenance and labels.
Cabinet No. 40 is a Complete Collectors Workspace: private catalog, virtual cabinets, Care operations, Exhibition/subcollection publishing, provenance and sold lifecycle, Mindat-assisted species data (BYOK), printable labels from the same records, and marketplace listing on paid Curator plans. It does not include club dues or club website tools - by design.
What collectors usually need from a catalog
Privacy by default - a private collection without a separate privacy upgrade.
Virtual cabinets and physical placement - shelves that mirror how you store stones.
Provenance timeline and sold/gift/trade lifecycle - ownership periods that close when a specimen leaves.
Printable collection labels - museum-oriented PDF labels from the same specimen record.
Bulk Excel/CSV import with duplicate detection - migrating an existing spreadsheet.
Strict IMA nomenclature + Mindat-assisted fill - species data in the catalog workflow.
Care and sensitivity workflows - reminders and hazardous-specimen coverage.
Public exhibition pages - curated subcollections with field-level sensitivity.
EU data residency for international collectors and dealers.
Cabinet No. 40 covers that core path on Hobby (with limits on specimen and photo slots). Geology365's public materials emphasize club operations more than this catalog depth - that difference is the useful comparison.
Cabinet No. 40 - collection first
On every plan (including free Hobby):
Virtual cabinets - drag-and-drop shelves, multi-cabinet layouts.
Care center - overdue reminders, sensitivity coverage gaps, cabinet-level conservation ops.
Exhibitions - public gallery or guided tours from subcollections.
Sold lifecycle - realized price, close open provenance, optional buyer, clear placement, archive.
Excel/CSV import with fuzzy duplicate detection; CSV/XLSX/JSON export.
PDF labels from specimen data (built-in templates; PDF credit limits apply).
Wishlist, public collector profile, IMA knowledge base links.
Mindat assist (BYOK) - your Mindat API key for live species fill.
Privacy by default with per-field sensitivity.
EU hosting (Supabase EU). UI in PL, EN, ES, IT (and more locales in the panel).
Paid plans add capacity and power-user tools (see pricing): more specimen and photo slots, custom fields, visual label template saving, Field Mode offline drafts, financial/lab stats, insurance PDF, marketplace listing, and on Curator+ a public REST API + webhooks.
Geology365 - club platform with a catalog
Geology365 is a US-based platform with ties to the Eastern Federation / club ecosystem. Publicly it combines a collection manager with club management, a free club website generator, events, dues (PayPal), a presenter database, a US state club directory, and crowdsourced specimen ID.
Publicly stated catalog limits (geology365.com homepage footnote and /collection-management, checked 2 August 2026):
Free: 750 specimens; one condensed image per specimen.
$5 / month: 1,500 specimens (upgrade path stated on /collection-management).
Premium: unlimited specimens (same page); photo capacity and other Premium gates are described in their materials / Subscriptions tab when logged in.
Also public: reusable label design; QR to a public specimen page; spreadsheet import/export; Privacy Control as Premium; bulk label printing as Premium; mobile app as Premium plus a separate App Store / Play purchase (Play listing ~EUR 2.59 as of August 2026).
No public documentation we found for: virtual cabinets, Care/exhibition workflows, sold lifecycle depth, shareable wishlist, multi-language UI, or EU data residency. Contact and pricing are US-oriented.
Priorities that differ
Specimen count vs catalog depth. Geology365's free tier allows more specimens (750 vs Hobby 50); Cabinet No. 40's free tier includes the catalog workflows above within that 50-specimen limit.
Privacy packaging. On Cabinet No. 40, collections are private by default. On Geology365, privacy control is listed as Premium.
Mobile packaging. Cabinet No. 40 uses mobile web on all plans; Field Mode offline drafts are on Curator / Curator+. Geology365 offers a native app as Premium plus a separate store purchase.
Club tooling vs catalog tooling. Geology365 invests in dues, websites and directories. Cabinet No. 40 invests in cabinets, Care, exhibitions, labels and provenance.
Identification vs cataloging. Crowdsourced ID helps at a show; it is a different job from provenance, exhibitions and printable inventories.
Geography. Cabinet No. 40 hosts in the EU with multi-language UI. Geology365 is US-centric in structure and contact details.
