Ratings and reviews

My son & I enjoy this app. I am glad we can track what sets we have. But we have had an issue with the App. We were trying to fix a Lego set that some parts fell off, when he went to find the instructions, we noticed that he was missing a lot of the set that we had added in the last couple of months. It says he has 56, but he really has more than that. We added 2 Creator sets today and the set scaned, but they don't show up on the list. Hopefully, we still have all the books.

I absolutely love using this app. Going back to the printed instruction books after using the app for an extended period of time is difficult. The one feature that would make the experience better for me would be the ability to flip the orientation so that I'm able to charge my phone and use the app at the same time. The fact that the app is such a battery drain wouldn't be an issue if the app would simply change orientation instead of being fixed to one direction. Otherwise, it's great!!

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!

What's new

We've made the LEGO Building Instructions experience even more awesome. How? Well, we fixed some pesky bugs and improved performance in the app. Now you can build even bigger, better than before!
