Amazing learning tool

What a tremendous app this is. Perfect blend of information, usability (coolest zoom/expand feature EVER), and even the background music is perfect for a space information app. I wish you had more users and ratings, because this would be a very popular app if more people knew about it. Thanks for your hard work, and please don’t abandon the app or give up hope—it may take time, but this app’s eventual popularity is worth the wait!


Spock Would Say... Fascinating

Like one other reviewer wrote, this app is listed for ages 9 to 11. But this is easily an app that goes at the college level and beyond and is fantastic - at any grade level. It kept me fascinated in my doctors office for about 30 minutes.
Kids love it too. It kept my seven-year-old busy for about an hour one day. It’s a size relativity application, as it is kind of hard to explain what it does. Trust me at any price it’s worth it.

Easy & phenomenal

It is hard to explain how great this app is. On my first review more than a year ago, I thought it was phenomenal. After longer experience, I find it even better. Wow! I like the way I can compare sizes, eg, a whale shark and an African elephant. Try it on Apple TV on a big screen TV, for an even better appreciation of the immense variation of sizes. This app gives one an appreciation for the scale of the universe from the tiniest particles to the largest immensity.
