After crash-landing on an alien ocean world, survival is your only mission. Subnautica takes you from shallow coral reefs to treacherous deep-sea trenches and lava fields. Manage your oxygen, find food, and scavenge resources to craft advanced diving gear and submersibles. Build custom underwater habitats to survive the planet's diverse and often hostile marine life. This mobile version features a revamped touch interface, Cloud Saves, and optimization for the latest iOS devices.

Our Expert Score

95/100

The mobile port of Subnautica is a technical marvel. Bringing this massive, open-world underwater survival epic to iOS without losing the sense of wonder—and terror—is an incredible feat. The redesigned mobile UI feels natural, and the inclusion of full touch controls (and MFi controller support) makes exploring the 4546B ocean feel seamless.

What makes Subnautica stand out is how it uses atmosphere. Moving from the vibrant, sun-drenched Safe Shallows to the pitch-black, bio-luminescent depths is a harrowing experience. Building a base that you can actually walk around in, piloting the Seamoth, and uncovering the deep sci-fi mystery behind the crash is just as compelling here as it was on PC. If you have an iPhone with an A12 chip or better, this is the definitive survival experience on the platform. It's beautiful, terrifying, and completely immersive.

One of My All-Time Favorite Games Lives Up to the Hype on Mobile
Sun Jul 13 2025 barwreck

I never write reviews, but I felt I had to. I originally played Subnautica over a decade ago and it persisted as one of my favorite games over that time. So when I saw that they ported it to mobile, I was cautiously optimistic, but still had concerns about the optimization for mobile or the game losing the “scuffed” charm that the original had. I’ve played this version on mobile for two hours and so far I’m stunned how good it is. I’m using an iPhone 15 and my phone has hardly gotten mildly warm and I haven’t noticed dropped frames or stuttering of any kind. So far it still has its charm of not being perfectly polished like the original (the fins appear first when cooking garryfish, you abruptly get out of bases without a transition into water, etc.) while also having the heart and fun mechanics that I loved over ten years ago. Maybe the nostalgia is taking over, but of the games ported from console/PC to mobile that I’ve played, this really does seem like one of the best. Through two hours, I can’t recommend it enough, especially if you’ve never played it before

I love it but…
Sun Sep 14 2025 GglikeSapito

I love the game a lot, I always wanted to play it but I couldn’t since I didn’t had a PC or Console to play in, well now that I been playing it I notice several things but I’m not sure if they are bugs or glitches, first issue I had was that I built a scanner room but the actual scanner doesn’t works correctly whenever I try to scan for items it says scanning but it stays like that forever and never actually shows me or tells me anything, second thing I notice is that most of the times a creature tries to attack me even if there’s a wall in between the creature somehow it’s available to clip through the walls which it doesn’t make any since specially the reaper leviathan or other bigger creatures, third thing I also hate is how hot my device can get whenever I try to play for longer than 30 minutes and I know it’s not my device cause I play on an IPhone 16 Pro Max or an iPad Pro M4 why I say this is cause on other mobile games like PUBG or Farlight 84 the issue doesn’t even exist so I believe the game needs to be optimized a lot more, my last one is battery what I mean about battery is that the game drains so much energy from any of my devices I mentioned before is just unbelievable how fast my IPad or IPhone die whenever I play for a couple of hours plus the heat just makes me not want to play it even tho I love the game so much, all I ask is for a update that fixes these issues thank you.

Considerate Devs
Tue Jul 08 2025 Anatoliy B

I expected the game to just be a port where the devs slap some buttons on the screen and make it a pain to play like some other games, but with this game I was surprised the longer I played it the more I realized how considerate the devs were to make the game easy to play with touch controls. For example you can pull out your tools pretty fast and if your using a seaglide and your reticle is aiming at something that can be scanned you will have a little icon pop up to pull out your scanner the game will also pause when pulling out your tools very very nifty, also props to removing scanner scan time. Also thank you devs for giving us the option to play the game with max graphics I have a hard time seeing a difference between pc and mobile version and the game runs pretty smooth with occasional stutters but that's because I'm running max graphics I'm sure it will get polished out.

Great but nightmare for Prawn operators
Fri Dec 26 2025 Gunk3ater

I’m thrilled Subnautica made it to mobile platforms. It’s the type of game that makes you wish you can wipe your memory to experience the feeling of playing it for the first time again. It’s a game that’s not only a blast to play but the lore and story are novel-worthy. I’m a console player but figured I’d give it a try on mobile and I’m thoroughly impressed. The touch controls are well-mapped and make sense. My iPhone 14 runs the game really well too. My only gripe so far is that the Prawn suit gets stuck super easily which stinks because there’s a button in the pause menu that will move your character to an unobstructed position if you get stuck. When trying this in my stuck prawn, only my character is teleported (which I guess is what it’s supposed to do but it would be cool if it fixed my stuck vehicles though) and my prawn is left stuck with no way of moving other than destroying it and building a new one. I’ve tried grappling out, restarting my game, even ramming it out with my Seamoth to no avail. I’m on my third prawn now and I’m tired, boss. Word of advice: avoid tight spots with the prawn. Especially low ceilings.

Subnautica is a amazing game to play
Tue Jul 08 2025 Spidy_gaming

Subnautica is one of the best survival games out there I’ve played, good building mechanics, good gameplay mechanics, and the mobile port brings all the original experience from console and pc subnautica to this amazing Mobile port, You can even play it with a controller if you have one! I’ve been a Subnautica fan for years and I think they did an amazing job with this mobile port, 10 dollars well spent if you want a underwater survival game where you’re in the ocean with alien species and you don’t already have it, it’s worth it! However I wouldn’t recommend buying unless you want to play it on the go because if you already have it on console because switching between the two can feel a bit different. Other than that. This game is worth it and i recommend it for every one if they’re willing to spend the 10 dollars on the game

Pretty good on iPhone 12
Tue Aug 05 2025 Devilchaser

I am an original PC player and love Subnautica and Below Zero. I’ve got about 10 hours in the mobile version on my iPhone 12. The iPhone 12 is on the bottom of the compatibility list, and medium quality is the highest option for me. Pop in is a big issue, literally islands and whole biomes are invisible until you get close. I’m not happy about that, but the rest of the gameplay is excellent and smooth. Personally, I think my phone can handle more than what they’re offering. The phone runs fairly cool on the highest settings that I am allowed to use. The only reason I’m not giving this five stars is because of the terrible pop in issues on the iPhone 12. They’ve done a wonderful job porting this game to mobile. Controls are excellent, and gameplay smooth. Resource availability is lower and I think the biomes are smaller, but this is still a really enjoyable game and comes very close to the original experience.

Excited For More Ways To Play!
Wed Jul 09 2025 Ash2Ashe$

My 10 yr old son has been playing the console version of Subnautica for almost a year. We are glad that he can take his tablet around instead of a big bag with his gaming device. He enjoys the game by searching, building, and more. It’s not a particularly violent game and does seem to encourage things like critical thinking, exploration of the world, etc. I would highly recommend if you have an older child who loves ocean, science, or syfy. For adults: It is a great game. Several members of our family play. There are various modes to play and different zones to explore. I played on creative mode on the mobile app before writing the review since I’m still new to the game itself. The interface works pretty smooth. Graphics on iPhone 14 Pro Max are very nice! I plan to check with more of our devices as I know one is on the Low Resolution list.

Slight problem…
Tue Sep 02 2025 GH0st RAPt0R

I just want to say, subnautica is a great game and I enjoy it, but when the game went to auto save, it seems to be stuck. The same issue sometimes pops up if you save manually. I will have to exit the game and get back in and will bring me to my last successful save. This might have to do with the fact that it said my device wasn’t supported, I’m enjoying the game but since it auto saving won’t stop loading, it really is getting me stuck. I have around 30 gigabytes left of storage, so it shouldn’t be a storage issue. All I ask is to fix this glitch, and I can continue my game without having to reset to my last save. More recently, I’ve been experiencing a game crash when I get to close to the alien structure at the sunbeam drop point… I’m hoping I didn’t pay 10 bucks just so that I couldn’t finish the game. Thank you for reading.
