LEGO's official building-instructions app. Instead of a paper booklet, kids follow 3D steps they can zoom and spin to see each brick, for thousands of sets from 2000 to today. A Build Together mode lets several people split up one set: one person hosts and shares a PIN, and builders take turns on steps. Some themes add story content as you build, and a free LEGO account saves progress and tracks your sets and brick count. It needs an internet connection.
Our take: A useful free companion for any LEGO family, especially for siblings sharing one build; skip it if you prefer screen-free paper instructions.
