Foxar’s idea is to transform classic illustrations (diagrams, images, etc.) into animated, interactive 3D models that help everyone better visualize and understand school subjects and the world around us. Concepts like the Solar System, the human body, volcanoes, fractions, matter, sound, or the Moon’s phases become much easier for everyone to grasp. FOR WHOM? The Foxar app was designed for both classroom use (for students and teachers) and home use (for children, parents, and anyone who wants to better understand the world). WHAT CAN YOU DO WITH FOXAR? - Explore over 200 interactive 3D models - Follow educational guides: step-by-step tours that explain each model - View models in augmented reality, such as a cubic meter or a life-size sculpture - Test your knowledge with quiz models, earn 3D trophies, and track your progress - Share a model instantly via a link or QR code - Use Foxar in all possible languages FREE MODELS 60 models are available for free, without even creating an account. The Foxar+ subscription gives access to 100% of the library.
