Great to build with kids

Does a really good job of letting you see more of what’s going on and how it should look.

Latest update, still no design revert

Once more Lego have failed to deliver an update that actually fixes the biggest problem with the app, which is Home Screen layout now switching to a tile based approach.

The app has one job, make paper instructions obsolete but due to awful Home Screen layout it’s actually faster and easier dig through my instructions book pile, at least there the latest sets are always at the top and not in some random place.

I will be making another formal complaint and continue to do so until this broken layout and the idiot who designed it, the idiot who pushed it, and the idiots who tested this and said it was okay are all replaced.

Awful scan experience

I am using iPhone 13 and the scan experience for adding my new set is really awful. The camera cannot read the small QR code on the front page at all. When I tried to move closer, the QR code became completely blurry and unreadable. I know iPhone 13's camera is out of date, but this should not be the reason for not being able to scan. Please make the QR code bigger and clearer!

Poorly optimised

Gobbles iPad battery and crashes more times than I can build the damn pieces! Very poor excuse for an app, and from Lego! Shame on you!

this was a awesome app for me

this lego bulider instructions are nicer then the book it’s nice to finally understand something and where to place stuff without having to count the things so you can attach it, but it really helped even if it was kinda confusing
