The Vikersund ski flying app is a simple game where you play as a skier who is attempting a ski jump.  You tap to begin skiing down the hill and at the right moment you tap the screen to jump.  The goal is to get as far as possible during your jump.  You can play either single player or against someone.  Single player you have to beat scores which are computer generated, of course for multi-player you are going against your friend. 

Among the first apps I reviewed when I started blogging at iPhoneLife way back in 2008 (ages ago, I know) was a dictionary app--Webster's Collegiate (here for the review) from Paragon--and the basic concept then for finding word information was much like the TWIG Touch Dictionary for iPad now. You would start by typing a word into a search box, which would ultimately result in informative word results appearing. The similarities end there however, as to contrast that early app version of Webster's (while effective) with TWIG would be like comparing a Fiat to a Ferrari. The TWIG Touch Dictionary is truly an app worthy of iPad. It's clever use of a mind map-based interface and touch manipulation is stunning, both in terms of innovative design and elegance.

The Stone Age game is a fairly straight forward game with a top down view where you control a cave man who is out hunting for meat.  On the iPhone the controls are fairly simple with moving is done by tilting the device left or right.  Attacking is done by simply tapping the screen where you want to throw a club and defense works by swiping a finger across the screen.

If you are a Tumblr fan, and looking for an app that makes it easy to follow your favorite photo blogs (or find new ones), TumbleOn might be just what you have been looking for. In similar fashion to reader apps like Pulse, TumblOn leverages the smooth side-scrolling features of the iPad touch screen to make it easy to browse your favorite feeds. The app also provides handy quick-pick services that help you drill down on the best blog content, and even reblog it on your own tumblelog site.
