Curved Spacess is a flight simulator for multi-connected universes. Because light itself wraps around such a space, inhabitants see their universe’s contents repeating in a crystalline pattern, like a hall of mirrors but with no reflection. Curved Spaces is intended for undergraduates and graduate students studying 3‑manifolds, and has also found use as a research tool in topology and cosmology. Recreational math enthusiasts may instead prefer Torus Games, which offers 3D Mazes and 3D Tic-Tac-Toe in a variety of multi-connected 3D spaces, along with games on multi-connected 2D surfaces.
StarPromenade
Read full descriptionHide full description
This is a space travel simulator application. Using 3D stellar position data, you can experience realistic space travel. You can board a spacecraft that can fly billions of times faster than the ISS (International Space Station) and take an interstellar flight. During the flight, the positioning of stars changes, and familiar constellations are transformed into novel, never-before-seen shapes.

Verdict
The clearest difference is price: Curved Spaces at Free against StarPromenade's $0.99. StarPromenade's advantage is update cadence (every 2 months vs every 5 months). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
