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

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.

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.

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.

Several challenges are built into the game so you can compete with other humans from around the world to see who can go the fastest, fly the farthest, orbit with the least amount of fuel, land on the moon, and so much more.

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.

* Realistic rocket physics and orbital physics
* Sandbox mode
* Leaderboards
* Email your rocket to friends

Best Game Ever!!! Suggestion...

This is the best game ever! I really enjoy flying random rockets around, building space stations, and exploring the "smolar system". I bought this a month ago and it is still just as fun now! Definitely worth the $1.99 I paid for it. I do have a suggestion though... I think that rendezvousing with a satellite is way too hard. I either miss the satellite or run out of fuel before I can dock. Could you please make an "auto rendezvous" button (or something like that) that automatically takes your ship next to the satellite so building a station isn't so ridiculously hard?Thanks for reading this and I really love your game. Keep it up jundroo! 👍

P.S. Could we add some more parts maybe like a super huge fuel tank and engine?

Awesome game, next update additions for game

Next update additions: we should be able to have an astronaut that can leave the rocket like in real life, we should be able to carry rovers, lunar buggies, etc. basically real life space equipment, we should be able to explore planets with the space equipment we added to our rockets, we should be able to have a 3d view inside the rocket and be able to move around in the rocket, we should be able to customize our astronauts, we should be able to paint our rocket and design our rockets after building them. That's all the next update additions thanks for this awesome game. Please update the game with these additions

Very fun, needs one last touch

I very much enjoy this game, however it needs the last touches. Please figure out the coding to allow multiple anchor points. I'm sure this is more work and more complicated, but it's vital to having any stability and integrity in any rocket that's larger or pushing a satellite. Updating the app with this new coding would, in my opinion make the game significantly better as we wouldn't have to find structural tricks to overcome the weaknesses due to single point connections.
I still love playing this, but that would be great! And making solar panels refuel some propulsion system or fuel somehow would be fantastic as well! Maybe allowing satellites or ships to "refuel" themselves or at least boosters while in orbit.
