Just tried it out now, so not a comprehensive review, but i do have a feature request: to be able to click on/touch a piece in the parts list and get a list of steps the part is used in, so if you have one or two pieces left over (that aren’t just extra pieces) […]

Works great with brand new sets that have 3d instructions. The QR code makes it easy to add them to the collection. However, if you are trying to find sets you have had for a few years into your collection, it requires scrolling til you find it. You can’t search set numbers. I’ve given up […]

Terrible app since the update. Takes ages to load. If you go away from the app for more than a couple of minutes, it crashes, and you need to force close and restart it. Why can’t you store the build offline to avoid this?! FYI, I have reinstalled this app and I have a top […]

The app seems to be getting worse. Struggle to register sets as it keeps taking you around in circles, jumping from the app to the web, constant maths questions, then when you think it’s worked, you go on the app and the set isn’t there. Very slow to work. Just becoming very frustrating to use.

Good building assistant, but, and there’s always a but. Color saturation is bad. White or clear, I spent a good 20 mins looking for a 1×1 white block. When I was about to file a missing piece, I came across a clear 1×1 block. Same issues with black and charcoal (dark grey). It’s not as […]

Every Lego set ever with pdf downloads for each set even the very first sets that came out you could also use the instructions to build sets with the cheaper no name brand bricks that you can purchase in bulk and build similar if not the same things as long as you have the majority […]

really great App, no in app purchases, no ads, easy to use, gives you 3D instructions that you can turn any direction to get a better view of where each piece goes, makes registration of your sets for rewards program easy, and helps you organize your sets and keep track of which ones you have. […]

It appears to have all of the Lego sets both old and new for instruction purposes, but sadly a vast majority of them are not available for adding to the sets you own to it count the number of bricks you own. For the sets that are not shown in their themes menu, you can […]

Really glad to see they finally made an easy and accessible way to view build instructions, am able to get rid of so many instruction booklets. Would be nice if I could toss them all, but there are older sets from the ’10s that are not on here. The app is great the only reason […]

Phenomenal! When I was a kid, we didn’t have Lego building instructions on an app like this. They were only in paper booklets. This app is absolutely amazing! It gives very detailed step by step instructions on how to build a particular Lego set. Just enter the set number, and it pulls up the instructions. […]

This is perfect for people who want to keep their physical instructions in pristine condition. Only a few set that I’ve not found, but not a huge deal considering the size of the sets. That being said, you will be surprised at what small sets they do include. You can also “heart” sets that you […]

I can no longer log in to my Lego account. Therefore I cannot scan my new sets and receive the 20 insider points per set; I also can no longer see my large Lego collection. I adored this app until I ran into these gigantic issues rendering the app useless for me. I’ve tried uninstalling, […]

The app is great. You can search sets and scroll through different lego themes to see every set and what year they came out. I wish there was a wishlist feature on the app and also a feature that said which sets were retired/retiring soon without having to click into each set. Once those features […]

Love the app keeps track of all my sets for me and sometimes I like the digital instructions better cuz you can change the angles and see exactly how they put the pieces. But the only thing is when I go to register my set I scan the qr code and I go to get […]

New update is cool as it lets you link your account so you can track how many sets you have and how many pieces but it’s kind of buggy. Whenever you are building a set and have to come back later it has a resume build button you can click to immediately go back into […]

(4/5) March 26, 2023

This is a great app to use for both kids and adults who like to keep track of all the sets they have, and what I like most is how it counts up how many bricks and pieces you have altogether, regardless of set or theme. I have noticed that a lot of the older, […]

I would give it 5 stars if they didn’t update it around Sept 2024. Now it crashes or freezes constantly. I’m using a galaxy S9+, so meets the requirements, it’s just bugged now. Wish I could go back a version, that one never crashed or froze. Also, I see a lot of responses from Lego […]

I just discovered this app can track my collection. I added all the sets I could remember, and that were in the app. I hit 175 sets and over 110k bricks. I.. may have a problem. I can’t wait for future updates to continue adding older set support! Only negatives are that it is not […]

This is a five star app for the latest sets, hands down. But I had to dock two stars because the presentation of older sets is very poor. I decided to build set 21024 (The Louvre from the Architecture Series), but instead of the 3D presentation, you get a low resolution scan of the instructions. […]

Love the 3D instructions. Great way to get my daughter involved in complicated sets, she can move it around to see where pieces go (I can too!). Also love the cataloging of which sets we own, and we were able to find an old advent calendar and the instructions to reassemble the miniature sets! LEGO […]
