A LEGO® brick in your hand. Which set is it missing from? A tub of loose bricks, a few dismantled sets, and no way to tell what belongs where. BrickBack answers the one question that matters when you want to rebuild: this brick — where is it missing? IDENTIFY THE PIECE Photograph a LEGO® brick and BrickBack identifies it — its reference, its name, its colour. Recognition is powered by Brickognize, an online service: the photo goes to their servers for the length of the analysis, so scanning needs a connection. The app explains this and asks for your agreement before the first photo. If you decline, no image leaves your phone and everything else keeps working. You can withdraw your agreement at any time in Settings. MISSING FROM… BrickBack matches the identified piece against the incomplete sets in your collection and tells you which ones are waiting for it, in which colour, and how many. That is the heart of the app, and it is the first thing you see. WATCH THE PROGRESS RISE Mark the piece as found and the set's completion moves forward, copy by copy. You know at any moment what is there and what is missing, piece by piece and colour by colour. Spare parts are left out of the count. TEN BAGS, THEN THE POSTER Every tracked set has ten bags, which fill up with the pieces you find. Each time you pass another tenth — 10%, 20%, 30%… — a bag is sealed. At 100%, the set earns its poster: its photo grows, framed like a print, with a “Complete” stamp dated the day you finished it. In your collection, finished sets move to the “Completed” section, below “In progress”. THE SHOPPING LIST Gather the missing pieces into a basket, export it as a file the specialist marketplaces know how to read, or open the manufacturer's spare-parts shop. The price that counts is the merchant's: BrickBack takes you there, it does not make one up. The purchase happens at the seller. SET IDEAS From the sets you track, BrickBack suggests other LEGO® sets from the same themes. The calculation runs on your device, and the pieces you find for your sets in progress stay reserved for them. OFFLINE, AFTER THE FIRST SYNC The reference catalogue — over 28,000 LEGO® sets — is downloaded on first launch. It covers every theme, from LEGO® City and LEGO® Technic to LEGO® Creator, Friends, Ideas and Architecture. After that, browsing your collection, your inventories and your missing parts works with no connection. Only scanning and refreshing the catalogue need one.

The “With your pieces” mode, which counted them, has been removed. • With BrickBack Pro, “By theme” now shows every idea in the theme, with no cap. • The date you finished a set can no longer be lost when two pieces are checked off at the same instant. • An open set page now updates as soon as iCloud sync brings changes. ### 2026.9.29 — 2026-09-30 This update gives your sets' progress a new look, from the first bag to the poster. • Ten bags fill up with the pieces you find, and one is sealed at every tenth: 10%, 20%, 30%… • At 100%, the set earns its poster: its photo grows, with a “Complete” stamp dated the day you finished it. • In your collection, finished sets move to a new “Completed” section, below “In progress”. • Behind your sets' photos, a subtle dot pattern picks up their main color. ### 2026.9.25 — 2026-09-26 This update organizes your sets' inventory and makes it easier to read with large text sizes. • In large sets, parts are sorted into compartments by color family, then by shape: bricks, plates, slopes… • "Go to" takes you straight to a compartment, and each set remembers the ones you opened. • To see the list without compartments, turn off "Group by color" in the sort menu. • With an accessibility text size, the grid stays at three columns, and part numbers and quantities are shown in full. ### 2026.9.23 — 2026-09-23 This update makes BrickBack more reliable and easier to read. • The catalog updates as soon as you open the app, with set names in your language. • Parts are sorted by color and shown larger, in 3 or 4 columns of your choice. • The number shown is the one printed in the set's manual. • "I found one" now counts beyond two copies, and "I have them all" checks off a part in one go. • Your remaining free slots are shown before you add a set. • The camera turns off as soon as you leave the Scanner, so the app uses less battery. ### 2026.9.13 — 2026-09-22 No release notes. ## Related topics [lego blind bag](https://appshunter.io/ios/topics/lego-blind-bag) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
