The LEGO Builder app offers several innovative features that enhance the building experience. Its core functionality lies in the detailed 3D instructions, which allow users to interact with their models digitally. This feature supports zooming, rotating, and viewing sets from any angle, providing unparalleled clarity.

Another key aspect is the Build Together mode, designed for collaborative building sessions. By sharing a PIN code, users can join as hosts or builders, dividing tasks and completing steps in turns. The app also integrates a digital library of thousands of LEGO instructions, accessible via search or QR code scanning. Furthermore, users with a LEGO account can save their progress, build a digital collection, and track their total bricks built, adding a layer of personalization and achievement tracking.

LEGO Builder offers an extensive range of content that caters to both novice and experienced builders. The app provides digital building instructions for LEGO sets from as early as 2000 up to the present day, ensuring a vast selection for all interests and skill levels.

Users can explore enriched content and guided building experiences tailored to specific LEGO themes. This feature not only diversifies the building process but also injects additional fun and imagination into each project, making it unique and engaging every time.

The application is regularly updated with new digital building instructions, allowing users to continuously expand their collection. With this ever-growing library, builders can look forward to fresh projects and novel set designs that keep their experience dynamic and exciting.

LEGO Builder excels in maintaining user engagement through its interactive features such as Build Together, which allows multiple users to collaborate on a single project. By enabling friends and family to join via a PIN code, take turns completing steps, and work collectively, the app fosters social interaction and teamwork.

Additionally, by creating a LEGO Account within the app, users can save their progress, build a digital collection of their sets, and track the total number of bricks they've assembled. This personal investment increases retention as users are motivated to continue their building journey and celebrate milestones achieved.

Tracking completed sets and seeing accumulated bricks built over time gives users a sense of accomplishment. These features encourage longer sessions within the app and help maintain interest by providing tangible records of progress and achievements in LEGO building.
