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.

Drop a planet into empty space and watch gravity take hold of it. Pocket Galaxy is a 3D gravity sandbox where you place planets, stars and moons and then watch them orbit under real, physics-based simulation. Arrange a solar system exactly how you like it, then take it apart: heat worlds until they glow, freeze them solid, hurl asteroids, fire solar rays and set off chain reactions. There are no levels and no timers. The sandbox is the whole game, and the only clock is the one gravity keeps. What you can do • Sculpt entire solar systems from a near-infinite variety of worlds • Tune each world's gravity, size and orbit, even flip gravity to repulsive • Reach for cosmic tools: asteroid storms, solar rays, ice rays and explosions • Unlock new world and star types as you experiment • Discover procedural worlds, gas giants and glowing stars • Track your creations, and how life develops, in the Planet Journal • Save, load and screenshot your universe to share Relaxing and powerful at once, Pocket Galaxy turns real orbital mechanics into a toy box. Build a calm, life-bearing system, or smash it to particles; there is no wrong way to play it. This is the full paid version. No ads, no in-app purchases, no interruptions. Pay once and own the whole universe.

Verdict
The clearest difference is in-app purchases: Pocket Galaxy at none against SimpleRockets's 5. Pocket Galaxy also leads on ratings volume (10K vs 686) and review sentiment (95% vs 85%). SimpleRockets's advantage is update cadence (monthly vs every 2 months) and price ($2.99 vs $3.99). On rating, ads and device support there is nothing between them.
