If you had the power, how would you create the solar system? What would be the size of each planet or star? And how would you place them in orbit? If you are interested in Astronomy and looking for a powerful yet easy to use 3D universe sandbox app to create and simulate a whole new galaxy with realistic physics and gravity rules, then you’ve come to the right place. Pocket Universe, the 3D gravity sandbox game, provides you the ultimate power to explore the infinite space and simulate your own space full of different planets, gas giants, and stars.
In this gravity simulator app, you get to customize literally any aspect of these particles to simulate and design your very own pocket universe sandbox. Once you are satisfied with your customized solar system (or any other combination of particles, planets, and stars), you get to easily add it to your collection, take a screenshot and share it with the world.
Pocket Universe comes with a clean and neat design and the 3D simulation is so smooth that you won’t feel any difficulties or lags when bombarding your planets, or applying any condition to them. And make sure not to take the realistic gravity lensing effect as granted when looking at a black hole. It’s just fascinating.

Is Pocket Universe Easy to Use?
Is this 3D universe sandbox with realistic physics simulation powerful enough to create and design different planets, gas giants and stars? The answer is a BIG yes! But are the simulation tools easy to use? The answer is even a BIGGER yes! The user interface is so friendly, that you’ll get used to it after going through the step-by-step tutorial and trying available tools for a few times. After that, you just need to use your imagination and be creative to form some unique pocket universes with gravity simulator based on physics rules. If you are going to redesign our lovely solar system in our galaxy, you’ll have access to all the planets (mars, moon, earth, mercury etc …) and you have the power to unlock new worlds by meeting the right conditions, colliding with the right objects, and altering mass and sea level while keeping the temperature stable. To smash stuff together and create new planets, make sure to crash the right ones together.
Tip: To raise the sea level, hit a planet with ice meteors, and use rock meteors to lower the sea level.

My opinion, best game I played.


This is exactly what I was looking for from a mobile app, it does need some improvements, unfortunately I can't play long before it gets buggy or crashes.. Main issues are placing a wormhole, satellite or a black hole, causes the game to become unresponsive. Or after so many collisions, no matter what the settings are set to try and lower like graphics, Ect... The planets will suddenly eradicate all life on every planet, no matter the distance from the star even without a star, all turn into a lava planet within seconds
of spawning one. Also noticed that restarting a game for whatever reason, sometimes doesn’t work and either planets are still there, without names. I really want to see this app be updated soon so I can play the game I PAID for.
but I look forward to seeing some improvements. Otherwise it's a simple game, crashing planets, play with gravity, great graphics, the collision of impacts it's well worth it. I really enjoy this game, every game has its cons and pros, once more updates release, it'll be the best!

Now this is the story all about how My life got flipped, turned upside down And I’d like to take a minute just sit right there I’ll tell you how I became the prince of a town called Bel-air In west Philadelphia born and raised On the playground where I spent most of my days Chilling out, maxing, relaxing all cool And all shooting some b-ball outside of the school When a couple of guys, they were up to no good Started making trouble in my neighbourhood I got in one little fight and my mom got scared And said “You’re moving with your auntie and uncle in Bel-air” I whistled for a cab and when it came near the License plate said “fresh” and had a dice in the mirror If anything I could say that this cab was rare But I thought nah, forget it, yo homes to Bel-air! I pulled up to a house about seven or eight And I yelled to the cabby “Yo, homes smell you later!” Looked at my kingdom I was finally there To sit on my throne as the prince of Bel-air

So much fun!


Update to 4 stars due to some bugs:

After playing for a few hours I have run into a few glitches and found a few features that need a change. Like others have said sometimes objects don’t move and have no pull even though it’s set to unlock. The scale of the black holes is all over the place. They were once big and now they are really small. At first I thought I forgot to slide the mass scale but it was all the way up. I wish the planet count wouldn’t reset to zero when placing a solar system. I wish you could zoom out more. You’re kinda limited to seeing half a solar system at most. Would be cool if you could zoom out to a level where you can see most of the objects on the board. Also, sometimes the texture reverts back to NES days where the lines are jagged and sharp instead of smooth and detailed. Closing out the app completely will fix this.

Where are the supernovas? Quasars? Neutron Stars? And it would be cool if the planets that develop life would colonize other worlds and try to defend against all the bad things I do to their planet like send asteroids to wipe them out. This game has so much potential and I hope the devs use their imagination to make this a truly out of this world experience.

This game is a ton of fun. A truly great physics engine. I highly recommend it.
