Powerful tools for every collector
Everything you need to catalog, organize, and share your collection — wrapped in a clean, intuitive interface.
Wishlists
Never lose track of a sought-after piece. Build wishlists for any category, set priorities, and check items off as you add them to your collection.
Tag & Filter
Organize everything exactly the way you want. Create custom tags for any attribute — condition, era, origin, or value — then instantly filter to find exactly what you're looking for, or browse every tag in one place and see how many items match.
Charts & Statistics
Turn your collection data into beautiful insights. Visualize totals by category, see how many items carry each tag, track estimated value over time, and discover trends you never knew existed.
Supports Any Collection
Coins, trading cards, vinyl, stamps, licence plates - it doesn't matter. Each collection has its own fields, from text, numbers and dates to prices, locations and barcodes. Give every item several photos and crop them to fit, and scan a barcode or QR code straight into an item with your camera.
Import & Export
Already keep your collection in Excel, Numbers or Google Sheets? Import the spreadsheet, photos and all, and export any collection back out as a spreadsheet with its photos. Want to show it off instead? Save a grid of your items to your photo library and share it with other collectors.
iCloud Sync
Your collection is always with you. iCloud sync keeps everything up-to-date seamlessly across your iPhone, iPad, and Mac — no configuration required.
Frequently asked questions
What collectors ask most before they start cataloging.
What kinds of collections can I track with Classifier?
Any of them. Classifier isn't built around one category, so the same app works for coins, trading cards, vinyl records, stamps, books, action figures, licence plates, or something nobody else collects. You define the collections and the tags, and the app adapts to how you already think about your items.
Does Classifier sync between my iPhone, iPad, and Mac?
Yes. Classifier uses iCloud sync, so items you add on one device show up on the others automatically. There is no separate account to create and nothing to configure — if you are signed in to iCloud, it just works.
Is Classifier free?
Classifier is free to download from the App Store, and the single download covers iPhone, iPad, and Mac.
Can I track what my collection is worth?
Yes. Classifier turns your collection into charts and statistics — totals by category, estimated value over time, and breakdowns that make trends easy to spot across a large collection.
Can I keep a wishlist of items I don't own yet?
Yes. You can build a wishlist for any category, set priorities so you know what to hunt for first, and check items off as they join your collection.
Can I export or share my collection?
Yes. Classifier exports any collection as a spreadsheet that Excel, Numbers and Google Sheets all open, along with its photos, which makes a handy backup too. You can also save a grid of your items, or a single item, to your photo library and share it with other collectors.
Can I import my collection from a spreadsheet?
Yes. If your collection lives in Excel, Numbers or Google Sheets, save it as a .csv or .tsv file and Classifier imports it as a new collection. Each column becomes a field and each row becomes an item, and you can bring in a folder of photos with them. See Import and export in the user guide.
Can I use Classifier as an inventory app for my collectibles?
Yes. Classifier works as a collectibles inventory: every item lives in a searchable catalog with your own tags, totals by category, and estimated value over time — useful for keeping a record for insurance or just knowing what you own. Unlike a general stock-counting inventory app, it's organized around the things collectors care about, like condition, era, and what's still on the wishlist.
What do I need to run Classifier?
Classifier requires iOS 18.6 or later on iPhone, iPadOS 18.6 or later on iPad, and macOS 15.6 or later on Mac.
