Say you are out with friends at a restaurant and you decide to split the bill and figure out the tip. What are you to do? Well, you could figure out the calculations with a pen and a napkin. Or, maybe you use that plastic tip calculator card that you got from your local insurance agent. By far, the slickest way to do it would be to use your iPhone.

If you don’t have a “Beautiful Mind” or blessed with Mensa-like math abilities, you should use tipTapp. This nifty application takes the total bill, your desired percentage of tip and then the number of people you want to split amongst..

Personally, I think it is tacky to split a bill down to the penny but some people feel differently than me. Although this application works well for the iPhone, if you have installer.app the application iSplit is a little more useful as you aren’t dependent on a connection.
