About this app

Developer Description

Discover Your Place in the Universe

The range of size in the universe, from the tiniest particles to the epic galaxies—we take you on a journey of size that lets you explore it all with a single swipe. How big is a planet, compared to a human? And how small is an atom really? You can’t fully wrap your head around the scope of things by just reading about them – so this app lets you experience them in comparison to get a feeling for their true scale. By simply swiping you can zoom in and out all the way from the world of fundamental particles up to the largest galaxies at the edge of the observable universe.

Seamless zooming between the scales of 10^-35 meters to 10^26 meters (no math required)

Amazing fun facts for various scale levels, like the smallest bacterium and the largest black hole

Tap any object for an explanation of what it is, how it works, and our favorite mind-blowing facts

Beautifully animated illustrations of more than 250 objects

Original Kurzgesagt music to complement your experience

It's an amazing app, it helps you understand how small (or big) we are in the universe, I was definitely impressed with the scales of what's out there in outer space. I loved the explanations, they are very easy to read and have examples that improve everything. The art of the illustrations is very beautiful and the music is relaxing. It is an amazing app if you like to read and are interested in science in general. Completely worth buying, I don't regret it. 😊

Was very happy to have a way to send a little bit of money to kurzgesagt (without buying a calendar). This app is full of interesting info (and at least one cute easter egg). Only complaint, and a warning: when you first open the app, it very suddenly starts playing extremely loud music.

it's a very cool scale map, but there is literally nothing more than that in the app, i feel misled

I love Kurzgersagt. Been watching their videos for years and have been waiting to get this app. I was very disappointed to see that I can only zoom in and out. I cannot move around and zoom in on specific objects. Its fixed to the centre when it zooms. Thats very restrictive. I have apps that let me zoom around the solar system and move around the 3D environment. I knew this would be a 2D app but i still expected to move around a little.

Brown Dwarfs are shown to be smaller than Earth, despite the description stating that they are 14 to 90 times greater than the size of Jupiter. Uranus it not shown among the other planets in our solar system.
