What2Tip is the one app that belongs on your iPhone or iPod Touch. What2Tip is a very simple and effective tool for calculating the proper amount of tips when dining out at your favorite restaurant. Everything is on one screen. What2Tip is faster and easier to use than a calculator. It's a great tool to have when sharing meals with friends and a must have for business travelers or road warriors.How is What2Tip different from other tip calculators?- It's clean- It's easy to use- It's fast- It's FREE!GraderGuy gives What2Tip 5 stars and says "Functional, fast, accurate."
