Free on iOS 16 and iPadOS 16
The collection tracker for iPhone and iPad
Classifier organizes any collection on your iPhone — coins, trading cards, vinyl, stamps, books, figures, license plates — and keeps your wishlist with you wherever you go hunting.
Your collection, in your pocket
The point of a collection tracker on a phone is that it is with you at the shop, the show, or the estate sale. Classifier keeps your entire catalog on your iPhone, so when you are standing in front of something you might buy, you can check what you already own instead of guessing.
A wishlist that stops duplicate buys
Build a wishlist for any category and set priorities so you know what you are actually hunting for. Check items off as they join the collection. It is the difference between browsing hopefully and shopping with a plan.
Tag it the way you think about it
Every collection has its own vocabulary. Classifier lets you create custom tags for whatever matters — condition, era, origin, value — and then filter instantly to pull up exactly the items you mean, even once the collection has grown well past what you can hold in your head.
Made for iPad too
The same free download runs on iPad with iPadOS 16 or later, which is a comfortable middle ground: more room than a phone for entering details and browsing your collection, and still portable.
iCloud sync, no setup
Items added on your iPhone appear on your iPad and Mac automatically. There is no separate account to create and nothing to configure — if you are signed in to iCloud, your collection follows you.
Also on Mac
Cataloging a big backlog is easier at a desk. See Classifier for Mac or read more about what Classifier does.
