This app simulates the chaotic movement of a metallic pendulum above three magnets - You can change simulation settings such as gravity and friction - Create beautiful fractals based on your gravity and friction settings This app is completely free without any ads or purchase options and intended entirely for educational purposes.
4D Draw
This app allows users to draw and visualize four-dimensional figures using color to represent the fourth coordinate. It includes a help menu with drawing tutorials and creative ideas to aid in understanding 4D space.
- Draw 4-dimensional figures
- Use color for the fourth coordinate
- Built-in 'How to draw' guide
- 4D construction ideas
- Visualize 4-dimensional space

4D Draw is a simple vector-graphics app that lets you draw 4‑dimensional figures. It represents each point's first three coordinates in the usual way, while using color to represent the fourth coordinate. A built-in Help menu includes a “How to draw” page for an easy start, followed by a page of “4D construction ideas” to set you on your way towards visualizing 4-dimensional space. 4D Draw is intended for geometry students who want to learn to visualize 4‑dimensional space. People looking for a more recreational introduction to 4D should begin with 4D Maze instead. People looking for an even more recreational introduction to modern concepts of space and symmetry may enjoy the Torus Games or KaleidoPaint.

Verdict
The clearest difference is rating: Magnetic Pendulum at 4.0 against 4D Draw's 3.4. Magnetic Pendulum also leads on review sentiment (100% vs 70%) and iOS requirement (15.2 vs 17.1). 4D Draw's advantage is update cadence (every 7 months vs every 56 months) and device support (3 vs 1). On price, ratings volume, ads and in-app purchases there is nothing between them.
