"AR Solar System" turns your device into a telescope in augmented reality for the observation of the planets of the Solar System. Choose and place a planet or several planets in the scene: in your home (in the air, on the floor, on a table, on a wall, on any horizontal surface) or outside the home (ex. open sky)... Observe the planets of our Solar System as you've never seen them before! The planets available for observation are: Sun, Mercury, Venus, Earth, Moon, Mars, Ceres, Jupiter, Saturn, Uranus, Neptune, Pluto, Haumea, Makemake, Eris The software uses the information available on the planets of the Solar System to animate the rotations of the planets: every second corresponds to one hour, each planet rotates at the real speed, in the direction of real rotation. For each planet data are available such as size, rotation period, period of revolution, type of atmosphere, gravity, etc... Walk in the scene with your legs moving between the planets (like travel in space) and observe them with your device like a telescope: - approaching the planet you will see more details such as craters, valleys, plains, mountain ranges, etc... - moving away from the planet, you will see the planet entirely or more planets together - turning around the planet you can see the side of interest or simulate the flight of a spaceship orbiting the planet - by moving over or under the planet you will be able to observe its poles - etc… Interacting manually with the planets you can: - Move the planet in the real scene (pan gesture: dragging a finger on the planet) - Enlarge and shrink the planet (pinch gesture: pinching the planet) - Rotate the planet around its axis of rotation (rotation gesture: rotating the planet with two fingers); manual rotation deactivates the automatic one - Remove the planet from the scene (long press gesture: holding a finger on the planet for half a second) - Add a new planet to the scene by touching the desired position (using horizontal plane in real world or feature points) - Select a planet from the scene and display its characteristics (double tap gesture: tap a planet twice with a finger) Background of the scene: in the presence of light in the real world the milky way and the stars (deep space) are projected as the background of the planets on the walls of your house or in the sky if you are outdoors; in the absence of light (or covering the camera with a finger) moving in the scene will seem to travel in deep space (virtual reality feature… the real world will be removed from the scene). Useful for all those who love to observe the planets of the Solar System in every detail, for teachers, scholars, students, astronomers, etc... UNIVERSAL APP: - You pay only once and run on all your devices
Gravity Type
This app transforms typing into a playful physics sandbox. You can type letters and emojis, then manipulate them with realistic physics, including springs, strings, and collisions. It's a fun way to interact with text for those who enjoy a less conventional approach to word processing.
- Real-time 2D physics
- Letters and emoji with mass
- Springs, strings, and collisions
- Copy and paste functionality
- Eraser tool

Verdict
The clearest difference is price: Gravity Type at Free against AR Solar System PRO's $0.99. Gravity Type also leads on rating (5.0 vs 1.0) and update cadence (every 2 months vs every 46 months). On ads, in-app purchases and device support there is nothing between them.
