iCollect Everything vs CLZ — Which Collection App Is Better? (2026 Comparison)

We get asked this question a lot: “How does iCollect Everything compare to CLZ?” Fair question. CLZ has been around since the early 2000s and they make good software. We’ve been building iCollect Everything since 2013. Both apps help you catalog your stuff. But they take very different approaches.

Here’s the honest breakdown — what each does better, where they overlap, and which one makes sense depending on how you collect.

The Fundamental Difference

CLZ gives you five specialized apps. CLZ Movies, CLZ Comics, CLZ Books, CLZ Music, CLZ Games. Each one is focused on a single category with deep features for that type of collectible. You buy them separately.

iCollect Everything gives you one app for everything. Movies, books, music, comics, games — plus action figures, Hot Wheels, LEGO, stamps, trading cards, wine, dolls, coins, and about 15 other categories. One app, one subscription.

That’s the core tradeoff. If you collect strictly movies and nothing else, CLZ Movies is a fine choice. If you collect movies AND action figures AND board games? CLZ wants you to buy three apps (and they don’t even cover action figures or board games). We put it all in one place.

Switching from CLZ to iCollect Everything

If you’re already using CLZ and thinking about switching, here’s what you need to know:

You can export your CLZ data as CSV and import it into iCollect Everything’s desktop app. The CSV import tool lets you map CLZ’s fields to ours during import. Most data transfers cleanly — titles, barcodes, formats, notes, and dates.

Images may need to be re-scanned or re-downloaded depending on how CLZ stores them. Barcode rescanning in iCollect Everything will pull fresh cover art automatically.

It takes about an afternoon for a typical collection. One of our users recently moved 3,600+ movies from CLZ Movies and said it took about two hours including spot-checking the data.

The Bottom Line

If you collect one type of media and want the absolute deepest database for that one thing, CLZ is a solid tool with a long track record.

If you collect across categories — or if you collect anything outside of movies/comics/books/music/games — iCollect Everything is the better fit. One app, one subscription, 25+ collection types, and a free tier to try before you commit.
