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 price: 4D Draw at Free against Unfold's $0.99. 4D Draw also leads on update cadence (every 7 months vs every 14 months). Unfold's advantage is rating (4.2 vs 3.3) and review sentiment (84% vs 67%). On ads, in-app purchases, monetization model and device support there is nothing between them.
