Comments on LEGO® Builder: 3D Instructions for Android

★★★★★ Cadence (Cade) · May 25, 2026

Soooo much better than paper instructions!! I love that you can zoom in on things and rotate the models for the instructions and make sure that you're putting the pieces in the right places!! Also, you can earn points just by finishing lego sets!!! I love this app so, so much!

★★★★★ Duane Liburd · May 31, 2026

I truly love the LEGO Builder app. It's a lot easier to use instead of the building manual that comes in the box. You can definitely build your Lego's much, much easier and faster. I will continue to use the app. As a matter of fact.... I encourage everyone to use it.

★☆☆☆☆ Lood Birk · May 12, 2026

Since the last update the home screen where you see your own sets are confusing and hard to navigate. It just plain sucks. Please bring back the list or at least an option to list view your own sets. 1 star for this stupid change

★★☆☆☆ Olexij Gray · May 16, 2026

I like the app and would use it more, but it's poorly optimized for tablets. On my Galaxy S10 phone, I can load and start using the app in about 5 seconds. On my Galaxy A9+ tablet, the sits at the yellow load screen for about 6 minutes. Then it sits at the title splash screen for another 2-3 minutes before finally letting me access the home screen. Both situations are using the most current version of the app as of May 16, 2026. The phone is using Android 12 while the tablet is running ver. 16.

★★☆☆☆ Jason Rutland · May 29, 2026

won't load up stuck on yellow screen I've tried this on several devices and still yellow screen I even tried reinstalling the app and updating device updates but still stuck on yellow screen. I prefer using this app because I'm 51 and my eyes are not as good as they used to be plus it's easier to where you are upto in the build because I love taking my time to build especially if its one of the biggest. Come on lego sort out your app I think last update 6 days ago has stopped working for me
