LEGO Collection Tracker App: Best Options + DIY Way

If you’re hunting for a LEGO collection tracker app, you’ve probably noticed the same thing everyone does: the existing options are close, but never quite yours. This guide covers the honest landscape — then shows you how to build a tracker shaped exactly around your sets in Auto.

The existing apps (and where they fall short)

There are real tools out there. Dedicated LEGO collection tracker and database apps like BrickLink, Rebrickable, and Brickset are excellent for cataloging by set number, tracking parts, and looking up values. If you want a straightforward brick collector set tracker app with a massive database behind it, start there.

But those apps are built for everyone, which means they’re built for no one in particular. You can’t reorganize the shelf the way you picture it, mix your minifigs with your other collectibles, or make it look like the display in your living room. If you’ve searched “brickify collection tracker” hoping for something that just fits, the honest answer is: the best fit is usually the one you make yourself.

Build your own in Auto

Auto is camera-first. You describe the app you want, snap a photo, and Auto builds you a personal mini-app — a “Frame” — around it.

To build a LEGO tracker:

1. Open Auto and describe it: “Make a collection catalog that displays my LEGO sets on a wooden shelf, like a virtual bookshelf. Fetch set details automatically.”
2. Snap or import photos of your sets. Auto lays them out on the shelf and pulls in matching info.
3. Refine by talking to it — change the wood, resize items, add sorting, edit any detail. It updates live.

It takes minutes, and every choice is yours.

How someone built theirs

One Auto user built a shelf catalog this way, and their prompts are a great blueprint. They started by asking for a beautiful catalog displayed on a wooden shelf, with data fetched automatically for each item — inspired by the old Delicious Library look.

From there they iterated in plain language. They set up cover images to pull from the internet instead of their photos, then added an edit button so they could swap a cover from their camera roll or pick one online — and made sure tapping a result actually downloaded and applied it.

Next came the display: choosing between wood types like cherry, red cedar, red oak, soft maple, and ash, fixing a text-contrast bug on the picker, and adding shelf texture. They built a bottom toolbar with a slider to resize items and a toggle for titles, plus sorting by title or date added with an alphabet/year scrubber down the side.

Finally they generalized it — adding a filter so the shelf could hold other collectibles too, not just one type — and polished the detail screen with cleaner cards, spacing, alignment, and a per-item edit button.

That same pattern maps perfectly onto LEGO: sets on the shelf, box art as covers, sorted by theme or year. People have already built catalogs like the “Collector’s Shelf” Frame in Auto — proof this isn’t hypothetical.

FAQ

Do I need to know how to code? No. You describe what you want in plain language and refine by chatting.

Can it track more than LEGO? Yes. As the story above shows, you can filter one shelf across LEGO, minifigs, and any other collectibles.

Will it fetch set details automatically? You can ask Auto to fetch data and cover art from the internet, then override anything by hand.
