Very clunky app. They need a way to jump directly to a certain Lego bag. We resumed building and we're on step 8 of the old train shed, but the app started us over. now we have to click 9000 times, and mandatory cut scenes with sound slow that down. just let me choose the bag. and give me the option to disable animations.

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 !

excellent for building sets. It needs to have options for owning more than one of a set. The 3'n'1 sets, for example. I have multiples of several sets and don't have an accurate brick count. It would also be nice to add the vintage sets from the 1970s and 80s.
