Where did you buy that piece? What locality is it from? Which case is it in now? Specimen Log (標本帳) is a mineral collection management app. Record and organize every specimen — photos, locality, purchase source, price, storage location, and more. ------------------ WHAT YOU CAN DO ------------------ ▷ Record your specimens Save mineral name, locality, origin details, size, hardness, crystal system, purchase source, price, purchase date, condition, and free-form notes — all stored per specimen. ▷ Attach photos Add photos from your library or shoot directly in-app. Register multiple photos per specimen and swipe through them on the detail screen. ▷ Organize with tags Create custom tags for color, locality, show name, price range, or storage notes. Filter by multiple tags at once to narrow down exactly what you need. ▷ Switch your view Toggle between list view and gallery view. Browse by photo or scan purchase info and pricing at a glance. ▷ Manage shelves & cases (Pro) Register shelves and cases to track exactly where each specimen lives. No more forgetting which cabinet holds which piece. ▷ Analyze your collection (Pro) View spending by year and by purchase source, plus counts by locality and tag — all in charts.

Up to 10 items free; unlimited with Pro. ▷ Share your specimens Create a share card combining the photo and details from any specimen — easy to post on social media or share with fellow collectors. ▷ Export & import your data Export as CSV (data only) or as a ZIP with photos — free for everyone.

It is a collection log — a place to record specimens you have purchased or collected, in your own words.
