Relativistic vs RelativityTheory
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Relativistic
Explore the effects of relativity by adjusting the speed of light and observing real-time changes. Simulate scenarios like time dilation and gravitational blueshift by placing observers and celestial objects on a map. This app offers an intuitive method for understanding Einstein's theory.
- Adjustable speed of light
- Real-time relativity effects
- Observer placement and time dilation
- Black hole simulation
- Gravitational blueshift visualization
- Intuitive learning tool

Experience the world at the speed of light. Relativistic lets you set the speed of light to walking pace and then walk around your neighborhood and see the effects of relativity in real time. Place observers on a map and watch their time slow down and speed up relative to you as you move. Place a black hole at the end of your road and watch outside observers glow blue as you walk towards its singularity. Relativistic provides an intuitive way to learn about and teach the details of Einstein's theory of relativity.
RelativityTheory
Read full descriptionHide full description
Introducing and explaining the mysterious phenomenon derived from the theory of relativity. In particular, we will detail the changes in the way time progresses. The interstellar flight screen shows how time progresses in response to rocket speed. Shows the difference in how time progresses between rockets and the earth in space travel. The GPS screen shows that gravity changes the way time progresses.

Verdict
The clearest difference is price: Relativistic at Free against RelativityTheory's $0.99. Relativistic also leads on iOS requirement (9.0 vs 14.4). On ads, in-app purchases and device support there is nothing between them.
