Features & Highlights

The "LEGO® Builder: 3D Instructions" app is a delightful tool for both seasoned builders and newcomers to the LEGO universe. It transforms the traditional building experience into an interactive journey, making it easier and more enjoyable to construct your favorite sets. Here are some of the standout features that make this app a must-have for LEGO enthusiasts:

  • Interactive 3D Instructions: The app provides step-by-step 3D building instructions that allow users to visualize each step in real-time. Imagine building a complex LEGO spaceship; instead of flipping through paper instructions, you can rotate the model on your screen, ensuring you place each piece correctly.
  • Set Management: Users can easily manage their LEGO sets within the app. You can scan the barcode of your LEGO box, and the app will automatically load the instructions and details for that specific set. This feature is particularly handy when you have multiple sets and want to keep track of which ones you’ve completed.
  • Augmented Reality (AR) Mode: The AR feature allows you to project your LEGO model into your real-world environment. Picture this: you’ve just finished building a magnificent castle, and you want to see how it looks on your shelf. With AR, you can visualize the castle in your living room before deciding on the perfect spot.
  • Community Sharing: The app encourages users to share their creations with the LEGO community. After building a unique model, you can upload images and instructions for others to replicate. This feature fosters creativity and collaboration among LEGO fans.
  • Progress Tracking: The app allows you to track your building progress, marking completed steps and providing a sense of accomplishment. This is especially motivating for larger sets, as you can see how far you’ve come and what’s left to build.

    This almost ended my 6 year relationship. I build Legos with my partner every year for our anniversary. We did just fine without the app up till now. We tried the team building feature together for our last set and got so annoyed with having to pass things back and forth and leaving things unfinished. At one point we had 5 different Lego bags open, just waiting to be returned to! The order of instructions makes no sense. The team function is the only reason we got the app, and it was horrible.

    Ever since my Lego Builder app was updated I've been unable to use it. Any set I choose flashes me past the option to build. It used to be an incredible app, unfortunately it's been unusable since the last update. Lego reached out about the issue I am having and are working to fix the problem. I couldn't be happier with the response! Lego is a great company with a fantastic product and stellar customer service!

    Love the app! It's a great way to keep track of most lego sets and the 3d view makes it easier for the kid to build. However I do believe it could be better. It's frustrating when a set retires instead of showing the picture its a blank box and you have to figure out which set it is. Almost none of the small bag sets (polybags) are not on here which we wish they were so we didnt have to keep up with the small papers in the bag to rebuild it later or atleast to keep track of sets and pieces.

    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 easy to bulk add things, or add multiple copies of a set. But that is minor compared to it's primary use.

    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, retired sets are not all there yet, and some of the newer sets from this year are still not in the app's database (I assume it's a slow process). It would also be nice to include polybag sets as well to make the themes more complete.
