ORBIT is a gravity simulator at the heart of a puzzle game. Launch planets with a flick of your finger, and try to get them into stable orbits around black holes. Can you make enough orbits to progress to the next level? New: ORBIT now features a Sandbox (paid) where you can create your own levels! Control time, disable collisions, and paint with gravity. Publish your creations to the world for everyone to play. • 45 free levels, with new mechanics are introduced over time — like repulsive black holes and planets with their own gravity that attract each other • Play community-created levels — virtually limitless content made by other players, all completely free • Launch as many planets as you like, and watch the mesmerizing orbital mechanics unfold • Planets leave colored traces, so that at the end of a level you will have created a beautiful piece of art • See the future trajectory of a planet before you launch it • Play in an environment of smooth, minimalist graphics while listening to relaxing classical piano Follow on Twitter: https://twitter.com/highkeygames Follow on Facebook: https://www.facebook.com/highkeygames

About

Gravity Physics

Features
Read full description

Gravity is a real-time N-body physics simulation of our solar system — fly a spacecraft through accurately modeled orbits, gravity wells, and atmospheres, all rendered in a clean top-down view of the ecliptic plane. Every body uses real physical data: mass, radius, orbital elements, and atmospheric density where applicable. Gravity between all 26 bodies — Sun, planets, major moons, and dwarf planets — is computed live using velocity Verlet integration, so orbits, perturbations, and gravity assists emerge naturally from physics, not scripted paths. FEATURES • Pilot your own spacecraft — configure engine count, thrust, and mass, then launch from Earth • True N-body gravity — every body pulls on every other body and on your ship, in real time • Realistic atmospheric drag and heating — feel the difference between skimming Earth's atmosphere and diving into Venus or Saturn • Time controls — speed up months of orbital motion or slow down to precision-dock in real time • Trajectory prediction — see where your current heading will take you before you commit • Flight trail — trace your path across millions of kilometers • Extended telemetry — track speed, altitude, gravity, thrust-to-weight ratio, dynamic pressure, hull temperature, time dilation, and more Whether you want to attempt a Hohmann transfer to Mars, slingshot past Jupiter, or just watch the Moon orbit Earth in fast-forward, Gravity gives you a physically accurate sandbox to explore the mechanics of our solar system.

Verdict

The call

The clearest difference is in-app purchases: Gravity Physics at none against Orbit's 7. Gravity Physics also leads on ads (none vs shown) and update cadence (weekly vs every 2 months). Orbit's advantage is iOS requirement (15.0 vs 17.6). On price and device support there is nothing between them.
