PythagorasTree vs Four Dimensional Space
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
PythagorasTree
Explore the visual beauty of mathematical concepts with this app. It generates fractal art based on the Pythagorean theorem, allowing you to customize angles and colors. Watch the intricate patterns grow and shrink to understand the recursive process.
- Recursive fractal generation
- Adjustable triangle angles
- Customizable tree colors
- Interactive growth and shrink animation
- Visualizes Pythagorean theorem

The Pythagoras Tree is math art. A square trunk is drawn. The hypotenuse of a right triangle is laid on top of the square. From the two legs two new squares are drawn. This process is repeated recursively until there the size of the square is too small to draw. Here you can adjust the angles of the triangle and the color of the tree. You can also make the tree grow and shrink to see the steps in making the tree.
Four Dimensional Space
Read full descriptionHide full description
Enter a rotating black hole and explore a visual experience beyond the limits of three-dimensional space. This app combines a glowing accretion disk with a conceptual 4D tesseract projected into 3D space, creating a dynamic and immersive visualization. Interact with the scene by adjusting tilt, rotation speed, and gravitational lensing strength to reveal new perspectives and distortions. Watch as the structure shifts and bends under the influence of the black hole’s gravity. No goals — just observe, explore, and experience a different dimension.
