Description
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

I love it (mostly because it's from Kurzgesagt), but could you add Uranus and a button on the descriptions that has the narrator of your videos narrate it for us? Please? Also, the observable universe is obscuring its name and size on the main screen. Also add Gravatar, please. Also, Francium isn't the largest atom, Oganesson is.

This visual app showing the relative scale of things from smallest to largest in the universe is fantastic. Brilliantly and joyfully done. Captivating. Get it for your kids and enjoy it yourself.

What's the beef with Africa? It isn't to scale on the map or even shows up in the app. Not to sound like I'm attacking the brand, but I'm just a user who feels like there is no love towards certain end users. If it's not intended, it certainly feels that way. Even the video about Africa's over population had a different tone than the global OP. I've spent 100s with you all, and I just want to not do it without felling like the brand hates me. I'll give this app 5 stars once I see an Africa update.

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. It's fixed to the center when it zooms. That's 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 is not shown among the other planets in our solar system.
