Great. For remembering things. Perfect for comparing big and small, best app to kill time, but I have a bug, human 1000000th of the average size keeps changing every 2 minutes. Thanks for making my dad spend £2.00 for this game. You should fix this bug and make it free, so this app will be more like a experiment, 2nd bug (last bug) the game keeps starting at 1m and what's the thing at the top-right corner even for? I love the game (5 stars)

Only 3 bucks?? An easy to use app like this is so educational and inspiring for kids, it has the power to single-handedly change the course of a person's life to pursue the sciences. Back in the old days, when you had to buy a box, this app would have been worth at least 20. Exactly what I was looking for, just better!!

I am revising my rating just for the fact that the developers seem to really care about their app and their gamers, and I see the possibility that they're going to improve on it. for now though, it's just a one-minute analogous size comparison which can also be found on YouTube.

We are sorry that you didn't enjoy the app as much. 😢 Have you recognised the text information about an object when you click on it? If you want to learn more, click on the book icon and access links to online references and videos directly. This is quite a lot of information.😉 Do you have any suggestions for improvements? feedback.thx@gmail.com
