Ratings and reviews

Good building assistant, but, and there's always a but. Color saturation is bad. White or clear, I spent a good 20 mins looking for a 1x1 white block. When I was about to file a missing piece, I came across a clear 1x1 block. Same issues with black and charcoal (dark grey). It's not as bad as the white, clear, but needed to say again. Needless to say, it can't replace the books that come with it

great app, amazing detail in instructions and saves all of your sets for you. Also allows you to rotate a 3d picture for better detail with each step, saves a lot of confusion at times. I tried to set up my account so I canorder through it but it will not accept my "special code", fix that and ill gladly gives five stars! Recommend to any lego enthusiasts!

I love being able to find instructions for old sets, but the color is really bad on some. on some of the old batman sets, before the showed what pieces are needed for sets, everything is just a black blob. Also, recently the math questions aren't working when I try to add a set. Yhe question pops up but I can't input an answer.
