Jun 04, 2010 - Texas based independent developer Alan Hancock has released What2Tip 1.1, an update to his tipping calculator for iPhone, iPad, and iPod touch devices. What2Tip will calculate a tip in 2 steps. It also has the ability to split the bill. It's a great tool to have when sharing meals with friends and a must have for business travelers or road warriors. What2Tip can help them comply with corporate expense policies as many companies will only allow a certain percentage for a tip.
