Gravity! vs Relativistic
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Gravity!
Simulate the forces of gravity by flinging particles and observing their interactions. Create celestial bodies like planets and black holes, and customize their properties. Explore vast cosmic simulations with intuitive zoom and pan controls.
- Gravity simulation
- Particle interaction
- Create solar systems
- Add black holes
- Adjust particle properties
- Zoom and pan controls

This app simulates the effects of gravity. You can fling particles at each other and watch them interact. Create solar systems and galaxies! Make a planet and fling asteroids into it! Add a black hole and watch everything get sucked in! You can adjust the size, mass, and color of the particles! Zoom in and out and look around with two fingers!

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.

Verdict
The clearest difference is rating: Relativistic at 5.0 against Gravity!'s 3.9. Relativistic also leads on in-app purchases (none vs 1) and iOS requirement (9.0 vs 15.6). Gravity!'s advantage is ratings volume (18 vs 2). On price, ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Gravity! sells 1 one-off in-app purchase. Relativistic asks for nothing beyond the download.
Relativistic holds the better App Store score, 5.0 against 3.9. That said, the two scores are not equally well evidenced: Gravity! has 18 ratings behind it against 2, so its average is the more settled of the two.
