I liked this app this. Thought the 360 animation was amazing...But the app keeps re installing itself without permission. never had an app behave like this so rating 1 star .very strange. If they can fix this I will happily give it a better rating but for now I think it might be unsafe to download .

But before I even got to it, I had problems with the very start of the game. Pulling the left hand menu is very hard, sometimes nearly impossible. It is not very intuitive that the button-looking tiles on the screen are not meant to be pushed, but you need to pull the menu from the left hand and push the buttons there, which rarely works. I tried many times until I finally succeeded to start the game. It should be fixed because it's a real obstacle.

This app originally wouldn’t start for me so I posted a negative review. As you can see by the developer’s response below, they fixed it in the summer of 2025. It now works great. Very nice videos and overall a nice app. Thanks for making this app better.

The cost of purchasing the headset is worth it for this app alone. You really feel as though you’re in space, to be able to handle and even construct the satellite is just awesome. Amazing.

If you're into space, you've got to check out the Guardians of Earth app. It's a fun and interactive way to dive into the European Space Agency's planetary defense mission, Hera. The app offers two main kinds of experiences: First, you can play around with a virtual model of the Hera spacecraft using augmented reality. But the part I prefer is the immersive 360-degree video that takes you along Hera's journey to the asteroid Didymos. And, as a Queen fan, the fact that it's narrated by the legendary Brian May is a huge plus! The app is free, so I totally recommend giving it a try.
