LEGO® Collection Tracker App for Sets and Minifigures

Who this LEGO tracker is for

It is built for LEGO fans whose shelves keep growing. When you own dozens or hundreds of sets, it gets hard to remember what you already have, which sets are complete, and which boxes are still sealed. A searchable catalog on your phone answers those questions in seconds, including in the store, when a duplicate purchase is one impulse away.

Sealed-set collectors and investors use it to record what they paid, where they bought it, and an estimated current value, so they can see how a collection performs over time. Parents use it to keep track of their kids' sets, missing pieces, and instruction booklets. Adult builders use it to organize bulk parts, custom builds, and the bins they are stored in.

If you collect more than LEGO, the same app handles your minifigure series, trading cards, video games, or vinyl, each with its own fields.

What to track in your LEGO inventory

The app includes a ready-made LEGO template, so you can start with sensible fields and adjust them as your collection grows. Most collectors track a mix of these details:

• Set identification: set number, name, theme, subtheme, release year, and piece count.
• Condition and status: sealed, built, partially built, disassembled, or in bulk bins, plus whether the box and instructions are present.
• Minifigures: which figures came with a set and which are missing, or track minifigs as separate items with their own photos.
• Value: purchase price, date, retailer, and current estimated value. Formula fields can total your collection value or calculate the gain automatically.
• Storage location: display shelf, room, LEGO storage bin number, or box label, with printable QR labels for each bin.
• Collection status: owned, wishlist, for sale, sold, or lent to a friend.

Scanning the barcode on a LEGO box can fill in the product title and image through the built-in barcode lookup, so adding a whole shelf takes minutes instead of an evening. Sets without a box are just as easy to add by typing in the set number and name yourself, and up to 15 photos per item let you document the box, the build, and any damage.

How to catalog your LEGO sets

A LEGO catalog stays useful when it is quick to update. Most collectors settle into a simple routine:

1. Start from the LEGO template and create folders by theme, such as Star Wars, Technic, City, or Icons.
2. Scan each box or enter the set number, add a photo, and mark whether the set is sealed or built.
3. Add the price you paid and an estimated value, then use grouping and filters to see totals by theme, year, or status.

Watch the 1-minute demo

The app works offline, so you can check your collection at a LEGO store, a flea market, or a convention without a signal. When you need a full list for insurance, a sale, or a LEGO collection spreadsheet, export everything to Excel or CSV in a few taps.

You can also share a collection with family members as viewers or editors, which helps when a household's sets are spread across several rooms and builders.
