User Reviews

Users praise the app's 3D, rotatable instructions and ease of use, but criticize the recent UI overhaul for being clunky and hurting navigation, especially in the library and kit discovery. Some instruction pages are incomplete, causing frustration. Overall, it's a powerful tool, but the redesign has diminished usability for many.

Pros

3D visualization with rotatable model improves understanding and assembly.
Easy-to-use interface and clear, easy-to-follow instructions.
Helps improve the building experience over paper manuals and makes keeping progress/steps easier.

Cons

New UI/design is clunky, confusing, and hard to navigate.
Library is hard to find sets after update; large libraries are difficult to manage and the list view is gone or harder to use.
Instruction content quality degraded in places (many blank pages; mosaic-like kit view) after updates.

With this app it gets easier you won’t make a mistake

by So*****, 2026-08-19

This app used to be good to organize and see which sets were in your collection. The new home interface is terrible for seeing which ones you own or don’t own. Finding them is tedious and having to filter is terrible. Even when you go to add a new set, the list doesn’t have the icon to show if it’s in your collection already. You have to dive down into each one to see. Terrible updates. Not worth using anymore.
