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

Zoom from a planet's surface out to distant galaxies, then reshape the whole system with your own hands. Solar System Sim is a real-time gravity sandbox built on Newton's laws and real astronomical data. Every body you add, move or destroy recalculates the orbits of everything else, live. • Smash worlds together: impact craters carve into the surface, firestorms sweep the globe, and glowing debris rains back down. • Build your own universe: add planets, moons, asteroids and comets with their own size, mass and looks, or customise the ones already there. • Land anywhere: drop to a first-person view on any planet's surface and experience its environment. • Sculpt rings: add particle rings and watch gravity shape them in real time. • Witness real eclipses: solar and lunar, with real-world astronomical precision. • Follow comets: watch them streak past and interact with the bodies they meet. • Leave the Solar System: travel to remarkable nearby stars and find them within the Milky Way. • Feel the scale: see the true vastness of space, from a pebble-sized moon to the nearest galaxies. Whether you're here to learn how gravity really works or just to break planets with it, explore at your own pace. Start your cosmic adventure with Solar System Sim.

Verdict
The clearest difference is ads: Orbit at none against Solar System Sim's shown. Orbit also leads on rating (4.8 vs 4.5) and review sentiment (94% vs 80%). Solar System Sim's advantage is update cadence (every 3 weeks vs every 2 months). On price, ratings volume, in-app purchases and monetization model 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. Orbit sells 7 one-off in-app purchases and Solar System Sim sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Orbit holds the better App Store score, 4.8 against 4.5. Both are backed by a comparable volume of ratings — 7.6K and 4.1K respectively. Written reviews point the same way: 94% of Orbit's written reviews are positive against 80% of Solar System Sim's.
Orbit ships an update every 2 months, Solar System Sim every 3 weeks. The most recent releases landed on September 23, 2026 and September 24, 2026 respectively.
