It's quite good, but there's potential for improvement. Features such as an in-app wish list, an indicator in the top right of a set in the search section to know which sets you own in a specific theme, and a collection-sharing function for LEGO fans would be fantastic. Maybe in the future, something more complex, a friend list mechanism to compare collections or see friends' wish lists, making easier to choose a gift. Hope to see this app evolving in the future. Keep up the good work !

This app on my old phone ran too hot, but now with my new phone can run it. I wanted to build a set I didn't own, but I had the Lego parts, so I decided to use it. I have discovered that it is clunky to use and hard to read the directions even with zooming in. I would much rather buy the old set directions than use this app, or use it on a larger screen than a phone screen, why can't you use it on a Windows laptop for example?

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!

Thanks for taking the time to leave us this review! You won't be able to order sets via the app. What you can do instead is head over to LEGO.build/Shop-GPlay, where you'll be able to enter valid discount codes. If you need further help, our experts are available via LEGO.build/Service-GPlay. - Marine, LEGO® Customer Service
