Engage in space exploration and terraform new worlds in this fun and exciting planet building simulator rooted in real science. TerraGenesis dynamically animates entire planets with changing biospheres, all based on real data from NASA.

The universe is your playground in TerraGenesis! Colonize real planets in our solar system, planets created just for TerraGenesis and even alien worlds! When the world is in your hands, the possibilities are truly endless. Play TerraGenesis and start terraforming today!

TerraGenesis Features:

- Join one of four interstellar Factions, each lending different benefits for colonization
- Colonize entire worlds one step at a time, by creating pressurized habitats for your colonists so they can survive in hostile environments
- Terraform your planet to support human life by altering specific properties of each world, including air pressure, oxygen, sea levels and biomass
- Track your civilization’s progress and your world’s current status with the Stats Summary Page

- Colonize real planets from our solar system, including Mars, Venus, Mercury and even Earth!
- Terraform orbital satellites, including The Moon as well as the Moons of Jupiter, Saturn, Uranus and Neptune
- Build colonies on fictional planets, including Bacchus, Ragnarok, Pontus, Lethe and Boreas
- Terraform Dwarf Planets, including Ceres, Pluto, Charon, Makemake, Eris and Sedna
- Melt ice caps to create planet-wide oceans and seed the planet with life

- Build your own functioning ecosystem with interacting, custom organisms
- Start with 26 different phyla and add 64 unique genes to create all kinds of amazing organisms to inhabit your world
- Manage your lifeforms as they thrive in both terrestrial and aquatic biospheres
- Generate random worlds with complete surface and elevation maps, unique starting conditions and more

TerraGenesis is free to play and as an indie game it was important to us that all in-app purchases are entirely optional and not required for a full and complete experience.

Absolutely Love It

Trig student

Yes, this app is as cool as it sounds, if not cooler. While apps across the App Store get simpler, and frankly, more boring, TerraGenesis will bring life back to your game list. Literally! This app truly has the depth of a computer game, and it runs great. It is very realistic and everything generates very slowly and visually so that you can truly see your planet, whether it be in our solar system, on the moons of the gas giants, dwarf planets, or many many other options (at least thirdy, each with its own intense description, plus randomly generated planets). It is visually appealing, and very high quality.

This being said, the game may not be for everybody. You have to have SOME kind of interest in Geology or Astronomy to truly fall head over heels for this app. It’s still a great building and idle app if you don’t, but you may not be as fanatical about it as me. Also, as I said, it is mostly an idle app. You can have the moon’s atmosphere pressurizing in your pocket, but while on the app there isn’t a WHOLE lot to do other than manage everything for about 10-20 minutes a couple times a day. You will not be on this app all day, but the app will be on all day. Keep this in mind.

Overall, if you’re thinking “this looks pretty cool”, GET IT. Seriously. It is NOT pay to play, it’s not cheap, it’s not buggy, it’s not boring, but it is sexy. Do it.

Perfect for the right kind of nerd, so satisfying.


I preface that I’ve only spent 3 days making the Moon habitable, but it was so interesting. Watching the atmosphere rise up, dialing it in. Selecting locations for colonies too early and almost flooding them. Waking up the next day and discovering that, while my palladium and silver mines are thriving, my atmospheric pressure is off the charts and I have to invest in balancing technologies with all that money or two hundred years of terraforming will be for nothing.
This is the only game I’ve ever seen that says “do you want to see an ad to speed what you just built?”
But most of the things you build to create these worlds on familiar celestial bodies will finish in 5 minutes to 1 hour, and you can hurry them along with genesis points that are very easy to get by clicking a larpy “would you like to watch this transmission to gain gp/mining boost/culture boost?” and you can always click “no thanks” and just enjoy taking your time watching your desolate planet become a thriving world.
This is truly one of the best games within its very small niche. It’s just phenomenal and I thank the devs for sharing their hard work with us in such a polished manner. It will take me at least a month to get through the free planets, I’ll happily give them 99 cents for Jupiter in a few months.

Good game until Time Traveler event hit me 5 times.


I had this app for a while, and then deleted it to save space because I wasn't using the game anymore. I recently came back to it, and have been playing a lot. I was working on terraforming both Mercury and the Moon almost simultaneously, and had just about finished Moon. All I needed was some more water, as sea levels were just barely above minimum for habitability, and population to get Culture Points to reach 100% independence. However, I came back today and was hit in total with the "time traveler" event a total of 5 times within several minutes. For those unaware of the nature of the event, it stems from cheating by changing the time on your device. However, I was not cheating in any way and have hardly even been on my phone today. I went from a near-perfectly terraformed Moon with an almost perfect ecosystem to a Moon with over 2,000,000 pressure and total mass extinction of all my 20+ species, not to mention other terribly affected statistics (surprisingly though, oxygen was only a little over 1,000 ppm away from perfect). To top it off, my credits went from around 50,000,000 to 100,000 in a matter of minutes. I understand that the point of this event is to prevent cheating, but by randomly activating without me cheating all it has accomplished is driving away me and my money I was once considering spending on more worlds than the basic three you start off with.
