4D Draw vs Calcsharp Pro

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.

It uses a different approach from a conventional calculator, which is more natural to the way people calculate. When you calculate on a conventional calculator, each time you enter a new number you lose sight of the previous one. And if you make a mistake in the middle of a long expression, you have to start all over. In Calcsharp, you can see all of what you are calculating, and expressions can easily be edited and saved.
