great app I successfully built 2 Legos
this app is helpful amazing fun and 100% better than the paper instructions with LEGO® sets
Awesome app, the ability to build a set with multiple distinct instructions is great. I noticed on a small screen the app always starts by showing the parts needed for that step, and then you tap the screen to see where the parts go. There's a slide out tab to see what parts you need. On a big screen, it defaults to just the screen showing where to place the parts. Let me pick between these defaults. It's less about screensize and more about the set and how much repetition the set has.
LEGO® Builder App Review Rating: 4.5 / 5 ★ The LEGO® Builder app is an excellent modern companion for Lego fans. It updates the classic building experience without losing the magic of the bricks. 🌟 The Standout Features Interactive 3D Views: You can spin, zoom, and flip digital bricks on your screen. This completely stops the frustration of missing a hidden piece. Build Together Mode: This is a game-changer for families. It splits one big set into smaller, simultaneous building tasks.

I ABSOLUTELY LOVE this app....it's so helpful having a three d image to see how the pieces go together. I am 46 years old and put my very first lego set together about 1.5 years ago... I love doing this.I didn't know what I was missing until I found the joy in legos

I love that you can spin and flip the build piece to see exactly how to place the pieces.
i recently updated the app as hadn't used it for a while, went to use it to review the news sets coming out and nothing works, when selecting any theme, there is nothing available across any year, I wouldn't have thought its my phone as using recent samsung fold7

We found instructions for two different McLaren P1 sets (42172 and 75909) available in the app, although neither are available in 3D. Our team is always working hard to make more instructions PLUS, so keep an eye out for updates! ✨ -Jane, LEGO® Customer Service
Great alternative to using Lego instructions. I loved being able to look at all the different angles while building.
