Reviews for LEGO® Builder

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) you can more easily find where you missed them.

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 trying to add some of my sons sets as I can't find them. We will need to keep the paper copies for these.

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 of the live phone.

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 1x1 white block. When I was about to file a missing piece, I came across a clear 1x1 block. Same issues with black and charcoal (dark grey). It's not as bad as the white, clear, but needed to say again. Needless to say, it can't replace the books that come with it

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 of the right pieces. Absolutely an excellent app I could not ask for want anything more for free. If you are a lego fan this app is a must for if your looking to get in Lego this is the place to find the right set

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. you can close the App in the middle of building a set and when you open the app to continue building it, it will start you right where you left of without having to start again from the beginning

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 search for it in the searchbar and find the instructions there. It also lists the parts so you could manually keep track if you want. As an example, I have gotten about52 lego sets since 2007, of those 54, I found 13 in the themes

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 for 4* is their "about info" claims to have all instructions for sets from 2015 to today but I can not find at least 2 of my sets from 2015 on the app. Tried searching by set name, set number, and series.

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. It let's you zoom in and out so you can see every little detail on complex builds like Technic supercars. It also let's you spin and rotate the model in every direction. Absolutely stellar!
