I love this app! It helps you build your Lego set on digital!! And you can rotate it to see more! It's cool that you can do that stuff, But it has one problem! When I try to scan the QR code on the instructions, it doesn't work! And it's skinny! Even though it's right, it says it's wrong! Can you please fix this? But great app by the way!

I think this was my first Technic build. Somehow, when looking for the instructions (I prefer to use the online version), I came across the LEGO Builder. It took me a minute to get used to how it works. Now I'm going to see if it's available for my other builds. I hope so, it's such fun! Beware, the sound effect when you complete a section can be very loud! Made me jump several times in the beginning. I also like the accuracy of the colors of the parts. Thanks, LEGO, for this excellent app.

My son got the Z-Blob's Robot and Vehicle Adventures set and the 2nd half of the directions are only available on the app. But the app keeps crashing every time we try to open the 2nd set of directions. The first set (which came printed) opens fine, but the 2nd set won't open. I tried uninstalling and reinstalling and on multiple devices. It crashes every time we try to open the 2nd set of directions. My daughter got a similar set and hers opens with no problem.
