∞ Tipulator for iPhone available free on Friday only

Sophiestication Software is making its tip calculation software for iPhone, Tipulator, free on Friday for anyone who wants to download it.

[ad#Google Adsense 300×250 in story]Tipulator is a handy app that calculates the amount of money you should leave as a tip at a restaurant or other venue. You just enter the check amount, the percentage for the tip and you’re done.

The app does a few other things to make paying the bill a bit easier too. For instance, it will split the check between multiple people, leaving the guesswork out of how much each person owes.

Tipulator will also round the check total or tip amount automatically, if you want it to.
