Ultimate Sharks for iPad, from Discovery Channel, is on sale at a huge discount for this weekend only.  It’s down from its normal price of $9.99 to just $0.99.

If you have even a mild interest in sharks, this is a great app to have on your iPad. I did a review of Ultimate Sharks for iPad back in August of last year – you can have a look at that for lots of detail and screenshots from the app. In the meantime, here are some of its key features:
