** Apple Design Award winner and iPad Game of the Year! **
Enter the Darwinian world of a galactic mote. To survive, absorb smaller organisms and grow—but beware of larger predators. Osmos features unique physics-based play, stellar graphics, and a hypnotic ambient soundtrack. Absorb or be absorbed!

“The ultimate ambient experience” — Gizmodo
“Beyond doubt, a work of genius" — GameAndPlayer.net

you must grow by absorbing smaller motes, but to propel yourself you must eject matter behind you, causing you to shrink. From this delicate balance, Osmos leads the player through floating playgrounds, competitive petri dishes, deep solar systems, and more.

“Named as iPad Game of the Year for a reason, Osmos is a fantastic game. A combination of physics, survival and classic eat em up” — WeDoCode
“Whether you're a child at heart who likes mucking about with single-cell organisms, or a strategist with a physics degree, this game will appeal to everyone.” — App Store review

It needs better controls
kwkwlw, on 6/7/2018
The game is basically a cooler looking version of ogario , but Ogario has better controls . Please make the controls better.
I bought the iPhone app in addition to the iPad App...
Helicopter CFI on 4/2/2018
That had to tell you something... I liked the game so much on the iPad, and played it for years. Then when I found it was available on the iPhone X I just had to get that version. The best way to support game development is to buy the good apps! Well done. Still love it. PS: excellent game for headphones and commutes in the morning.
The Best
Erik Stone on 3/8/2018
Simply the best game ever published on an iphone.
Xyzzy999 on 2/25/2018
One of the most original, beautiful and fun games. Highly recommended.
Still one of the best
rallycar27 on 2/3/2018
Years later, this is still a great game. Happy to see the iPhone X update.
excellent game, no ads
John Geffre on 1/29/2018
I really love this game. I've had it for 24 hours and have played it for 16 of those hours. If I didn't have to sleep I would have played it for 24 hours! Realistic physics interaction. There are no flaws. Beautiful trance-like music. Gorgeous graphics. I need 100 more games just like this one. There are about 30 levels and none of them are frustratingly hard. About 5 levels are kind of challenging. And EVERY level is a joy. Bravo to the developer.
Space Odyssey
annyrutts on 1/20/2018
Fun and relaxing. If you are looking for a great game to play when your baked. This is it. And use headphones !!
TitanSK1 on 1/1/2018
This may be a great game but it totally messes up all of the settings in my phone. I deleted it hoping the changes would go away as I couldn’t close the little monster. A screen outline started showing up on other sites I was using. Maybe it was due to my later modeled iPhone but I am still trying to go in and retrieve my original settings. So far this is the most intrusive game I have hardly played.
No colorblind mode
QB4882 on 12/31/2017
I am colorblind and couldn't play after level 4, where you need to distinguish between red and green.
Buying for iPhone doesn’t get you iPad app
cso115 on 12/26/2017
I bought this thing on my iphone, planning to play it on my iPad, and it does not allow you to get the iPad version after paying for the app. You can only play the mobile-optimized version.
Marc Y. Liu on 12/20/2017
Developer responded to my review. The iPhone X update has me in tears. Simply great.
No longer any Bluetooth multiplayer
Woahcoolness on 12/16/2017
My brother and I would play Osmos on the way back and forth on long journeys, but the Bluetooth multiplayer feature (a long time ago) was removed. Now we can no longer play since we do not have access to a wifi network when traveling.
Very well made game
Rcx160 on 12/1/2017
You will enjoy it Immensely..!!
The good old days
Augie Rules!! on 11/20/2017
One of the best games for the iPhone since the beginning. I scrolled down to the bottom of the list of purchases and was pleased to find this gem. It needs to be on the front page again 🌶🌊
Very satisfying and immersive
peacetype on 11/5/2017
A well-made game. You would be hard-pressed to find any fault with it. This was one of the first iOS games I played years ago; it’s still one of the best iOS games out there!
Great game
Farlin Paulino on 10/8/2017
This game is a classic. It doesn’t even deserve to be called a game by how relaxing it is. You reaaaally need to play this with headphones on.
BrutallyBri on 9/16/2017
I love this game it's so much fun and relaxing
Still enjoyable
Eyemarten on 9/6/2017
I will never be deleting this app. Best app purchase ever!
Great game!
JustinOring on 9/2/2017
Love it. Simple and fun. My kids love it too. The new multi player was a great addition. Just love it. You won't be disappointed. ----------- Just glad they are still keeping the game up to date and working with new devices. Love the game. -------------- I do wish they would come up with new levels. I've been done with all of them for years. Only thing left is multiplayer and it takes a while to find people.
very good
Zhou0227 on 8/19/2017
very good
Still love this!
Naca Valley on 8/17/2017
I still play this from time to time and enjoy the ambience. Though tough at times it is overall a calming game!
Must download
roppad on 8/14/2017
Absolutely the best sound track, challenging and riveting game modes. Immense variety. Worth downloading and playing all day long. Stop reading and go download now.
5 stars
Moon&luna on 8/9/2017
I really enjoy this game. It's super relaxing.
Osmos rules
Mr. Krinn on 8/3/2017
I've been playing this game for years. It's the closest thing to video game meditation I've ever seen. Deeply challenging in some places and at the same time straight forward. I love when I understand how any given level needs to be approached. I love the music as well. Thank you Osmos team for an incredible game.
Just awesome...
Steb22 on 7/29/2017
Great visuals, music. Relaxing and mind crunching
Must have.
ElJefe40 on 7/28/2017
I forgot I had this ! I stumbled upon it again , last night on one of my last app pages . It's the Most original , challenging , visually stunning and addicting game. I love it.
One of the best quality games on the market
mseabass on 7/18/2017
Polished graphics, sound and gameplay. This is the only game my girlfriend will play with me and she loves it!
Amazing game that I never tire of.
yozhipozhi on 7/13/2017
64 Bit Support!
Fenris ICFI on 7/13/2017
With IOS 11 coming glad to see an amazing game updated for 64 bit support. I would have hated to lose this as it's a wonderful experience. Thanks guys <3
So far, it's amazing
DancinSalmon on 7/10/2017
The most relaxing game I have ever played. Truly let's you reflect on life and the universe in a way that no other game has done. Highly recommend
Cool soundtrack and mesmerizing graphics.
MStyles on 6/26/2017
I haven't played this in awhile and just picked it back up. A better challenge for physics minded types, but without the math.
Best iOS game of all time
Caleban on 6/24/2017
I love this game, how beautiful it looks, the way it works on an ios device, how long I can play it without getting bored.
GnosticHammer on 6/18/2017
Love the game. Very beautiful. Keep me captivated. Ran through it too quickly.
Just one problem
Yellow fire 3601110 on 6/13/2017
I deleted the game for now because the mechanics are to uncomfortable. If you simply add in a new moving system then I will start playing again
I've always loved Osmos
otokoyama on 6/12/2017
From the beautiful and simplistic game play to amazing and great attention to in game physics, Osmos is entrancing, interesting and a great stress reliever. It's one of the few apps I've kept on my phone not long after the iPhone came out. This game should get nothing less than 10 stars EVER.
Simple and Fun
Markymarkmarkington on 6/9/2017
What a great game! The mechanics are simple yet engaging. The control is well-suited to mobile devices. All in all very well designed!
Simply ... one of the best game you can find.
whm125 on 6/4/2017
6/5 stars.... yep, it is that awesome!
So fun!
Maaaahb2 on 6/2/2017
Great, unique, game. Definitely worth checking out.
Awesome game
Killer_N on 6/1/2017
Really fun game and was entirely worth it when I bought it for $4. It's similar to katamari damacy with some interesting twists. Multiplayer is fun although sadly they removed the ability to match up with friends, that said it usually works if you both seek a game at the same time. Additionally if you're in the same room you can also play multiplayer.
Astounding immersive experience
Dave-K on 6/1/2017
This game is an ethereal work of art. The incredible graphics transport you to the far ends of some unknown universe, where you can play many single player challenges and once you've got the necessary skills, you can go up against players around the world. One feature I miss is the audio chat that was built in previously. It turns out I Med one of my great lifetime friends on osmos so I'm ever grateful for all the superb programming that made it possible. There is this other game called Agar.io that is some kind of faint shadow of what osmos is, that tries to be similar. Osmos is just galaxies better. The meta games in the game are great. Just look at master osmos gameplay on YouTube for an example of my gameplay from a few years ago. I'm glad they are updating the software and I hold out hope they will expand the game and add new features for the billion plus iOS users out here.
Osmiasf1988 on 6/1/2017
I was in fear that this game was going to go out of date, happy is not the word, joy is the word, Thank you for the update. It remains, the only game I have kept on my two phones for more than 2 years!!!!! It is challenging and fun. Elegant in its simplicity , and pleasant to look at. The music choice is calming and etherial appropriate to this video game.
Buy this game
DHawlSmalls on 5/31/2017
If you only can get one game it should be this one, you won't regret it. Beautiful graphics and sound design, mesmerizing, addictive, and infinitely replayable! Keep the updates coming, and release an app version of Karmaka already!!
Best game
hafman42 on 5/31/2017
My favorite iOS game. Played since it came out. Refreshing my review after the update. Osmos is still my favorite game
Brilliant, Relaxing
NewZack on 5/31/2017
Sometimes I play games at night to help my mind settle down, and this game is quite relaxing. I enjoy it enormously. It's just difficult enough to keep the attention, but not so much to be frustrating.
Lemmot on 5/31/2017
Still fun as ever and I love the calming music!!!
Kungurofgfg on 5/31/2017
Thank you for updating!
/dev/zero/99 on 5/31/2017
I was just lamenting that I would no longer be able to play this soon because it was 32 bit, and lo and behold here is an update to 64 bits. For free! Thanks!
Love this game
GordonChil on 5/31/2017
App refresh resets reviews. I haven't reviewed it before so here I go. This game is very well made. I've had it since it was first released on the iPad. I keep going back to it because it's so pleasing to play.
Awesome game
LugnutWF on 5/31/2017
So relaxing, I play it on my phone and my PC. Refreshing review due to update.
Fantastic game
Sunrunner20 on 5/31/2017
