Gravity Simulator

It's a good start. It just need some UI improvements. And more content, options and parameters to work with like being able to adjust the density and mass separately, being able to customized colors or use more realistic colors when a star's mass reaches certain mass levels and when planets have a certain atmosphere composition. You can also probably add different elements that users can choose from (periodic elements) for them to mix around and make unique planets like gas giants and rocky planets with liquids and atmospheres. Since elements have different densities, planets should form layers from its core to its atmosphere. I know this is a gravity sim, so that is why most of my suggestions for content are related to gravity (since elements have mass). Seeing how liquids and gases interact in this gravity sim would be interesting to see. You should also add options to be able to select celestial bodies and see information about them and being able to choose to view a 2D representation of spacetime warping as the simulation runs using gridlines. Also add tutorials for noobs. Also make it easier to make moons and planetary rings. Just continue developing this app. Your app is the only app I've seen so far that applies momentum during collisions. But it still needs the other types of collisions so that debris can form when planets collide. You can also probably add an option to enable light to be emitted by stars so planets can cast shadows to make it more realistic and somehow more appealing. And another option to lock screen view on a celestial body. Oh, and lastly add a SAVE SIMULATION option. This app has potential. Keep developing.

Needs a orbit feature. It's very difficult to get an object to orbit the sun. Good concept, can be great! Just needs some work, keep it up!

Everyone the reason your planets are falling into the sun is because u aren't giving it enough velocity

OK, but 2 dimensional so you can't create true solar systems. Fun to play with for a short while.

I've been looking for one for a while and this is it! However, I hope it will be optimized soon. I have the note 4

Add more things of different densities, and maybe a visual representation of gravity.

THIS IS LIKE FLYING CIRCLES

Just ok

Big Bang type action

The app itself seems good, I feel it perhaps needs an indication of scale and a tutorial of some sort. I've managed to get a few planets orbiting at once. It seems that you must move your finger as you spawn it to give it some velocity. Im not sure if this is deliberate functionality. Obviously if the velocity is beyond the sun's escape velocity it will just fly in to nothingness.

The physics are fine. as we know gravity warps spacetime, which means yes if you simply put a planet down in will simply be drawn into the sun, which is similar to real world space. what you need to do is flick the planet on the right angle, close enough to the sun to be caught in a gravitational orbit. My only suggestion would be to make the effects of gravity more intense, seeing as the limits of the orbit are only about the length of Mars to out sun. however, I can just increase the suns mass to fix this

Installed! Now what? I great a sun. And each planet falls into the sun. If I flick a planet, it shoots off beyond the screen never to be heard from again. Okay those actions are seemingly worthless. Now what? Oh, never mind, I know what to do next.......uninstall.

I think everyone saying the physics is off is wrong, and most likely don't understand how orbits work.

Firstly their is an orbit you guys don't know how to play nor briefly understand gravity. Good game but would be good if we could change the size and mass of planets and sun's

I hate that there are so many people who don't know how to get the planets in orbit (flicking the planets next to the star) and are immediately rating bad...

Is there a way to keep the view centered on a given object ? The star keeps sliding off the screen due to the added momentum left by colliding objects, which is understandable, but it would be nice to be able to lock the center on it so that I don't have to recenter manually every few minutes.

Can you add orbit paths to objects and predicted orbit trajectory when you're about to launch it? People that say they can't make planets orbit star needs to think harder, though. If you flick the screen and the planet escaped, at least try to flick it less harder until it gets to orbit. Creating planets from planetary disks (asteroids) is brilliant!

Its a great game you can summon a giant sun and do other random things so yeah u shud get it

All the retards who say I doesn't work just never listened in high school.

Made a massive star, then made a large planet revolve around the sun. Then i shot asteroids at the planet until it was in the orbit i wanted! Cool game.

Doesn't work get a sun down throw some planets in and nothing planets do whatever not orbiting flying away and asteroids just fly into the sun making it bigger

It's good actually. But adding more feature maybe like black hole or recreate the path since you can't change the course of the sun or other if you already swipe

As soon as I put a star down and put asteroids around it, they collide into the star.

Surprisingly resourceful! This simulator is very clean and simple. I highly recommend this for anyone who is even remotely interested in nuclear dynamics. So basically, everyone.

It has no orbit

Like it like how it's so awseom

If you can add names then i will give you a star

Great app too

It looks amazing!

Made me think

Really?

Nah...

So simple

5.18/1.65

A fairly standard affair - functional but lacking in features. The suns are stationary (so things like binary suns are not possible), and asteroids/planets just follow their trajectories and merge upon meeting with basic trajectory changes.

As soon as one makes a sun then it is over. Watch every object no matter how massive fly into instead of having an orbit like most planets would. Also if you leave an area it's only a matter of time any object you created there will be forgotten, and no this is not after you exit the app but as you play. If you are hoping to make a mini solar system this app is not for you. However, if what you really want is to see white circles and red circles crash into each and get bigger and bigger then this your app.

There is a problem the gravitational pull isn't really like those in real space. hope you fix that.

I've been looking for one for a while and this is it! However, I hope it will be optimized soon. I have the note 4

I can't make earth big
