What learners can create with Flock XR
From simple scenes to personalised interactive worlds, Flock XR helps learners code, design and experiment in 3D.
Code 3D worlds with blocks
Create interactive 3D worlds using block-based coding that is great for beginners and powerful enough for progression.
Design directly in 3D
Use design tools and gizmos to place, move and scale objects visually, making world-building more intuitive and creative.
Personalise and remix
Built-in personalisation makes it fast to create endless variations, so a few blocks can lead to many different outcomes.
