Create Lissajous curves by combining the horizontal and the vertical motion of an electron beam on an oscilloscope. Tap the screen to get a spirograph like representation of your curve. Change the amplitudes, the frequencies and the phase difference to change the curve. http://www.youtube.com/watch?v=hN9jMaT_Zu8
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: DR.Lissajous at 4.5 against 4D Draw's 3.4. DR.Lissajous also leads on iOS requirement (9.1 vs 17.1). 4D Draw's advantage is review sentiment (70% vs 50%) and update cadence (every 7 months vs every 23 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
DR.Lissajous holds the better App Store score, 4.5 against 3.4. Both are backed by a comparable volume of ratings — 2 and 9 respectively. Written reviews complicate that: 50% of DR.Lissajous's written reviews are positive against 70% of 4D Draw's, so the app with the better star average is not the one people write more warmly about.
DR.Lissajous ships an update every 23 months, 4D Draw every 7 months. The most recent releases landed on November 1, 2026 and November 6, 2026 respectively.
