I love this app is it alike Cozmic Zoom. Here is why I rated it 3 stars. One thing is that it is very difficult to zoom out and in without it doing it itself. Can you make a setting where you can zoom without it also zooming? Another thing is that it resets you every time you get to the end. Can you also make a setting to turn that off too please? Another thing is that the thing still goes to fast in my opinion even on the slowest. Can you make an option to make it slower in the settings? Otherwise, this app is great if you fix these problems I would rate 5 stars

I still have my flip book of stills from the video POWERS OF TEN as well as the VHS tape. This takes the concept to the next level. Now with this app we have the 3D experience to enjoy!It’s a great gift for everyone from children in school, to deeply religious adults of all ages. It gives you a concept of scale from large to small. Each person can interpret the story their own way. You can be a part of a greater whole, or a special part made especially for this time and place. No matter how many times you look at it you’ll learn something new.

I like the app but I don’t like how you have to by an upgrade. I waited for 2 hours for this to work and I can barely use it because I would have to buy an upgrade.

The reviews of this have been rather odd. It's a simple but elegant way to browse scales with some useful annotations.The Demo mode is the video basis for a recently "viral" video -- usually zillions of views. Worth it just to use the Demo mode (no musical soundtrack though).I bought it for $1. It's supposed to have ads that are removed for $1 but I haven't run into them so far.Bought it so I can force the kids to watch it and get unwanted education. Also good way to say thanks to dev for a quixotic effort that has languished for years.
