Fixed an issue that sometimes prevented large saves from being sent to the cloud.
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
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.
Features

Tips & Walkthrough
Start by catching Bladderfish for water and Peepers for food. Use the Fabricator in your Life Pod to make a Scanner as soon as possible; scanning wreckage is the only way to unlock blueprints for advanced tech like the Seamoth.
Gameplays
Don't just live in your Life Pod. Build a Habitat once you have the Habitat Builder. Bases provide more storage, power for recharging tools, and a safe place to plan your expeditions into deeper, more dangerous biomes.

I LOVE SUBNAUTICA
Tue Mar 17 2026 Low Res SubnauticaSo I have decided this is one of the best games I have ever played it’s SOOOOOO FUN I LOVE IT and it works on my iPad because I’m playing on an iPad mini gen and it’s listed as unsupported but it works it’s just bad graphics (except for the water even with bad graphics it looks AMAZING it’s the best water I have ever seen in a game) but there is one problem when I get to the alien structure on the island the one that is big it kicks me out I don’t expect you to fix it because you guys say my iPad is unsupported in the description just mentioning it and I hope one day I can get it on my laptop or download it back when I get a new iPad (btw I have had this iPad since I was 6 or 7 no pun intended and now I’m 11 so it’s pretty old but it works) also I really really like the mechanics and driving the cyclops and sea moth I think that is what it was called I kinda forgot and one more thing I really like the story I haven’t completed the game yet and I don’t think I can because of that bug where it kicks me out but I have watched walk throughs and I like playing in creative so yeah that’s my review on your game I hope one day I can finish the game on my laptop with amazing graphics😄 bye i can’t wait for Subnautica two to come out
I love it but…
Sun Sep 14 2025 GglikeSapitoI 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.
One of My All-Time Favorite Games Lives Up to the Hype on Mobile
Sun Jul 13 2025 barwreckI 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
Loved it on the Switch, Love it on Mobile
Fri Jul 25 2025 VincentAnalI’ve played and beaten this game once before on the switch, and I’ve spent years and years watching YouTubers play this, so when I heard it was coming to mobile I knew immediately I had to get it to see what it was like, especially after recently getting an iPhone 16 plus. They did a fantastic job on this. I was honestly stunned with how good the game looked, and the movement was smooth even with the restrictions of mobile controls. They managed to make sure the UI still isn’t overbearing either and I appreciate that. I also think making it on THIS version where things scan instantly instead of depending by size was a good addition and can help any new players looking to get into the game in a smaller way not get frustrated. Of course you have to keep in mind Subnautica is a VAST game that’s now on phones and tablets, not hearty console wires. Even though it runs smooth at 60fps, if you’re looking to play the game for more than an hour or so your device will definitely build up some heat. I’m not sure if tablets are resistant to it but my phone was starting to get hot, granted I get so immersed in the game I can play for 2+ hrs at a time and have to force myself to stop lol. So yeah. Overall, a phenomenal game that (I personally feel) was flawlessly transitioned into the mobile genre, and I couldn’t recommend it enough for anyone just scrolling the App Store looking for a new game to try. This is easily one of the best experiences in the App Store and I mean that wholeheartedly.
Great but nightmare for Prawn operators
Fri Dec 26 2025 Gunk3aterI’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.
Considerate Devs
Tue Jul 08 2025 Anatoliy BI 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.
Impressive mobile port, but not without issues.
Wed Jul 16 2025 PlayerOfLegoGamesThe Subnautica mobile port runs amazing on current gen IPads, even the render distance and load-in time for textures isn’t too bad. Unfortunately, the controls however, can be kind of clunky, and a bit buggy. Survival Knife controls are beyond terrible. You will almost never hit anything that isn’t totally stationary with it. Even Cave Crawlers, which have less available directions than ascending, descending, turn-on-a-dime fish are ridiculously hard to hit with the knife. Chief among the issues is that the tiny knife button is controlled by the same hand that controls the camera, so by the time you have your target in your sights, they move out of your camera angles so you have to readjust the camera, rinse repeat ad infinitum. Good luck using the Thermal Blade upgrade! You will never cook a single fish with it, because you have trouble hitting large targets, let alone tiny fish. As for the controls being buggy, the virtual joystick frequently has a bug where it will reset back to center when your finger clearly has it pulled all the way in one direction. This bug can and will get you killed when you’re running away from something. Haven’t gotten far enough to encounter a Leviathan yet, but I can guarantee this WILL be the death of me when I do. Overall, I give this mobile port 4 stars, considering it is a very good port of a very good game. If this control issue and control bug respectively are fixed, I think it would be 5 stars.
Pretty good on iPhone 12
Tue Aug 05 2025 DevilchaserI 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.
