Be sure to check our new game, SimplePlanes. Build airplanes and test them with realistic physics and see how they fly. You can find it on the App Store now or check out the website at http://www.SimplePlanes.com Design your own rocket ships. Blast off into space. Explore the solar system. See if you have what it takes to be a rocket scientist. CREATE Choose and connect parts together to build rocket ships. You can choose from a variety of rocket engines, fuel tanks, and other gizmos. You can even build rovers with powered wheels. You are only limited by your imagination. EXPLORE Blast off from any planet you want. You can fly through the intense atmosphere of Venus, or you can take advantage of the low gravity of Mercury. Whip around the sun and launch yourself out to the far reaches of the solar system. CHALLENGES Several challenges are built into the game so you can see who can go the fastest, fly the farthest, orbit with the least amount of fuel, land on the moon, and so much more. ROCKET SCIENCE Kepler wrote the equations 400 years ago, and SimpleRockets uses those equations to model extremely realistic orbital physics. Players will learn about rocket science and astrodynamics while they are having a blast exploring the solar system. This makes SimpleRockets ideal for the classroom, or as a healthy alternative to the barrage of brainless games available on the App Store.

Build your own universe, then rule it like a god. Pocket Galaxy is a 3D gravity sandbox where realistic space physics meet total creative freedom. Spawn planets, stars and gas giants, place them in orbit, and watch a living solar system come to life. Then play god with it: heat worlds until they glow, freeze them solid, explode them, or smash them together in stunning destruction. Often called one of the best universe sandboxes on mobile, it's part relaxing toy, part hands-on physics playground. No levels, no timers, no pressure, just infinite space and your imagination. WHAT YOU CAN DO • Build a universe from a huge variety of procedural planets, stars and gas giants • Simulate realistic gravity and orbital motion in an open 3D sandbox • Act like a god: heat, cool, explode and smash planets to see what happens • Unlock new planet types by changing conditions across your solar system • Follow the planet journal to see how life develops on the worlds you make • Enjoy rich particles, atmospheres and destruction effects • Capture and share screenshots of your universe • Save and load your galaxies anytime RELAX, CREATE, DESTROY Nudge an orbit and let gravity take over, engineer a perfectly balanced system, or wipe it all out in a single cosmic collision. The sandbox is entirely yours. PREMIUM AND AD-FREE This is the full paid version: no ads, no in-app purchases, no interruptions. Buy once and own the complete sandbox. If you had the power, how would you build the cosmos? Download Pocket Galaxy and find out.

Verdict
The clearest difference is in-app purchases: Pocket Galaxy at none against SimpleRockets's 5. Pocket Galaxy also leads on ratings volume (9.9K vs 683) and rating (4.8 vs 4.6). SimpleRockets's advantage is update cadence (monthly vs every 4 months) and price ($2.99 vs $3.99). On ads and device support there is nothing between them.
