Particle Physics Simulator

Particle physics sandbox with n-body capabilities where the behaviour of the system is driven by each particle's gravity. Most simulation parameters are adjustable, like the gravity strength, the number of particles, the friction or the collision policy. Some of them can even be operated live during the simulation. Set your initial conditions and just watch the system evolve or intervene to decide the fate of the particles!
Features:-Real n-body physics simulation, pure gravitational interactions between particles.-Create walls particles can't trespass. Watch them bounce off.-Allow or not physically realistic elastic collisions or mergers between particles.-Configurable particle colorus.-Configurable background image/colour.-Configurable gravity strength.-Configurable particle mass.-Configurable particle size.-Configurable friction.-Accelerometer support.-Repulsive forces.-Shoot particles of different sizes.-Repulsive particles.-Static particles.-Simulation area: screen or big area with panning and zooming.-Enable or disable the central black hole which exerts a neat attractive force towards the center.-Enable or disable particle trails (disable to improve performance).-Modify simulation velocity in real time.-Particle-Particle and Particle-Mesh simulation methods. Use first for accuracy, use second for performance.-Display grid densities as background in Particle-Mesh method.

Check out the LIVE WALLPAPER version, it's free and it's also in the market! It will remain with the old version of the app by now.

Contact me if you have suggestions for new features or found any bugs.

I like this game pretty much and it's entertaining to watch random particles interacting with each other without actually colliding. I was wondering if particle count could be bumped up or can be entered manually?

Good app. I like how i can spawn particles with the touch of my finger tip. But when i press the "..." button nothing happens and i cant change or edit settings. Please fix this issue or my 2 star rating remains unchanged and i will NOT reinstall this app....

Works but after a little while they start streaking across the screen randomly then it crashes

Would not let me move app to SD card. The developer is asking me to justify why I would want to store files on my SD card : it's none of your business where and why I store files. My one star rating remains unchanged.

Good. Would be better if it actually fit in the palm of my hand like the desc said (I'm on tablet)

Well, I'm using an S20 Ultra and, even on this device, the app crashes very easily. Needs more work, guys.

Nice app but must add more items and plese increase the size because you have fitted lot of knowledge in few KB . I hope just this I had no problem with the app

Please make into an interactive live wallpaper! That'd be awesome!

This is literally the most pointless game, they dont even tell you what everything does and it is just so boring, i dont even know how it even has 3 stars it does not deserve any stars at all, and im not even being harsh, UNINSTALLED

Thanks so much this update fixed the problem!

why does the particles look like stars from space?

A. G. u. Sep 30, 2018     

I can't use any of the feature I see people talking about on the comments

The best app of its kind.

hey I wanted the settings to be left

It was pretty ok i guess

hours of fun LoL

Im confused

I like this app and I've had lots of fun with it, but I tried to install it on my new phone and it won't let me access the menu options... part of the problem is on Samsung for removing the dedicated menu button, but you are supposed to be able to long press the back button, or use a feature called the "assistance menu" to bring up the options menu. Unfortunately nether of these solutions are supported by this app. So I can't use it anymore. :(

This app is really cool, and the potential astonishing. Adding the ability to allow certain particles to only react a certain way with other particles(i.e. red and blue particles collide elastically, while red and yellow particles dont collide at all, and red and white merge etc. ) would be a phenomenal improvement. This app is extremely interesting, and this is the first and only time I've ever gave feedback on an app and I hope to see it improve with time and become even better.

Could use some improvements in custom ability like moving the black hole, and multiple particles knocking against each other seems to lose energy . Finally a phone should be able to process more than 50 particles at a time. (Not jealous I got s4)

This is a very interesting app, and all of the functions work as they are supposed to, no crashes ever. The only thing is that the design of the buttons needs slightly redone to make the app look more professional/release more space at the bottom of the page. But thats it!

gra. b. Sep 17, 2013     

Would love to see some more additions though. Like particles only merging under certain conditions, this could be dictated by whether the particles are moving fast enough to trigger a merge, otherwise they would just bounce off of each other. Just an idea, cheers!

The best billiyard game I ever had. There is one pocket in the center and, you know what, no ball falls there. Even some of the balls vanish over time. Amazing! CERN people will love to play this 3D billiyard game too. My phone was soooo empty and had a too much boring day, that's why I installed this game. And this game totally made my day. Pretty impressive.

Very clever - educative and plenty of scope for inventing games, by adjusting gravity, particle forces, resistance, introducing barriers etc. Has been keeping me occupied for hours experimenting with the settings. Thanks for making it available. Keep developing! I now have it on an S3 and it works really well.

You can get satellites, but to make this game superior, I suggest that once a star hits a certain age, it goes super nova! I also suggest you have smaller particles with each color resembling a recipe, collide together to make a textured planet. And a way to show the gravity power of a specific star.

Rob. F. Feb 23, 2014     

Please make the diferent sizes of the particles optional, I loved this game so much but now I can't make any of them the exacet same size anymore. Its so frustrating to have a game I loved so much hurt by such a simple change :'(

Joh. d. May 6, 2015     

A previous user has posted this same problem. There is no physical settings button on an s5, making the extra features unusable (at least from what I can figure out). You stated that there is a settings button (three vertical periods) in the bottom right corner of the app. I can find no such thing. Please fix this.

Ley. J. Feb 17, 2014     

Excellent physics simulator but needs to spawn particles throughout entire square when on enlarged background. Currently spawns them in device viewport, too close to the black hole and simulations end too soon. Also gravity & friction need recalibrating to be less destructive or easier to stay in the interesting ranges (sweet spots). I'm afraid I don't understand mesh mode so can't comment, but recommend more advanced features are pushed down into sub-menu. Gravity & friction should be quick access at top.

It gets pretty boring after a while, you should also add an options menu to finetune your settings. :\
