Don’t be a yo-yo. Be the master of your own Yo.YO! is unlike any other book App that you've ever seen. Those other eBook Apps are all so last century. YO! is interactive, YO! is informative, and YO! is fun(ny). Oh yeah, fun; how fun? Get this….. Read more

What's New in Version 1.1

Minor Version Update 1.1 (10 July 2009):

Several readers have complained about the method used for saving an edited Tab Bar button order (i.e., customizing the button order inside the “More” tab). This method for saving the button order has been corrected with this update.

You can still saunter into the Yo classroom where you'll learn about the science of ups and downs. Remember inside YO! there are six areas for you to explore:

* Science – learn what makes a yo-yo go, well, up and down
* YO! - enter the hallowed halls of yo-yo history
* Yo-Yos – looking for a yo-yo; start here
* Fun Time – give yourself a giggle, go ahead, you deserve it
* Teach – discover 10 different yo-yo tricks and stunts
* One YO Thing – ah, this is the BIG one, a digital yo-yo that you can play with on either an iPhone or an iPod touch

Confusing... Bad app. Sorry!

I didn't understand it at all! What was the point? Sorry...

Save your money! Worst app I've seen.

Information is not current and is badly formatted and organized. The history was interesting but is readily available online.

The few beginner tricks shown don't include pictures, let alone videos.

The virtual yoyo is a poor quality 5 second video clip of some guy throwing a yoyo down.

The list of yoyo models is highly limited - 25+ years old.

The author tried to write a game that you could pair 1990s celebrities to 1970s yo-yos... It seemed contrived and badly designed.

It seems like this app is the result of someone trying to learn how to code an app. It's mostly blocks of text... I read through it in 5 minutes, posted this review in another 5, and now I'm deleting it.

Save your money.
