Free on iPhone, iPad & Mac
The collection management app for collectors of anything.
Classifier lets you catalog, track, and carry your entire collection in your pocket — whether you collect coins, trading cards, vinyl, stamps, books, or pretty much anything else.
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.
Charts & Statistics
Turn your collection data into beautiful insights. Visualize totals by category, track estimated value over time, and discover trends you never knew existed.
Supports Any Collection
Coins, trading cards, vinyl records, stamps, books, action figures — it doesn't matter. Classifier's flexible structure adapts to any type of collection you can imagine.
Export & Share
Show your collection to the world. Export a beautifully formatted view of your items directly to your photo library, or share individual pieces with fellow collectors in seconds.
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, license 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 can export a formatted view of your items straight to your photo library, and individual pieces can be shared with other collectors in a couple of taps.
What do I need to run Classifier?
Classifier requires iOS 16 or later on iPhone, iPadOS 16 or later on iPad, and macOS 13 or later on Mac.
