If you travel to foreign countries, then you know that it's easy to confuse the different customs and practices. One such item of confusion is how much to tip someone in the different countries. Most of us want to be courteous and leave a tip, but sometimes it's easy to forget, mix up what the best amount is, or even if that country embraces the concept of tipping. This app will help you with tipping in over 240 different countries. Additionally, it helps with splitting checks, excluding tax, and more. It really has become a popular utility app among my friends and I as we travel a lot for work.
