I had no choice but to download this app as the instruction booklet was missing pages. It was a new set just bought from the Lego shop. Trying to use this app on a small mobile phone was challenging. I zoom in on the parts I need and the parts move around, making it difficult to identify what I need. Not a good app if you have a small screened phone. I have now got to the part of the build where I can use the book again, so I am going to delete this app

It's a good app. I've just had a birthday gift of lego sunflowers that came out this year (26) the app is brilliant because it gives a 3D view of the parts, very useful when building. But on older sets it's just a photo of the pages of the how to books that come with the sets, there's no 3D movement in the parts. Lego please update the app so that all the sets are in 3D. I'm 57 and I'm a life long fan of Lego.

Great app, my child prefers to use it instead of the paper instructions. However it gets stuck sometimes so need to close and open it again which is not a big problem as you can start it right where you left, but a bit annoying especially if happens more than once. Also, could be more 'video stories' about the set (like the detective boat we built the other day - it had a story with it and my child loved it!). He was entertained and didn't ask for my help !
