About this app
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. 😊

Very interesting app. Lots to learn. I'd recommend adding some sort of comparison feature where you can select 2 or more items and have them specifically compared to one another. For example, It would be cool to see mt. everest on the same plane with central park... Or an oxygen molecule next to the coronavirus... Ya know, for no particular reason...

This kind of website/app has always been enjoyable for me but Kurzgesagt's style adds a nice new layer to the experience. The music was also very unexpected and very pleasant, helping to create this whimsical mood as you swipe through these immensely large/small distances. Good sense of humor here too. My major gripe is that I am unable to reorient my screen while using this app, which is pretty dumb. This is really minor though and doesn't detract from how worthwhile this whole thing is.
