User Reviews

Users praise easy building, clear instructions, and collection tracking via profiles. The main drawbacks are the UI redesign, which many find confusing and hard to navigate on mobile, with some wishing for the old layout or an option to switch layouts. Overall, the app is helpful and enjoyable for Lego building, despite the interface changes.

Pros

Very easy to use; clear and simple instructions.
Rotation feature helps place parts accurately.
Shared build mode adds extra fun.
Saves built sets to your profile and helps track your collection.
Much easier than paper instructions; broad set availability.

Cons

The new UI and sets overview design is chaotic and hard to use; many users want the old categorized lists back.
Mobile layout changes make it hard to see what you own; tiles are too small and the view is less organized on devices like Pixel.
Some reviewers describe the update as garbage and want an option to switch back to the old layout or have both layouts.

Recent reviews

Everything I need in one place! Old broken sets that have lost their instructions can be rebuilt and so much easier to swipe than have to turn a huge page whilst building!!! Thank you LEGO!
