Tip Properly: GlobeTipping

Click Factor: Do you know how much to give a hotel porter in Tuvalu or a waiter in Bermuda? Don’t worry: it’s optional, according to this app’s tipping advice for more than 200 countries, from Afghanistan to Zambia, which make it the most comprehensive of the global tip calculators. Speaking of which, the app includes one, which will factor in tips by percentage and divide the overall bill by number of diners.

Drawback: Specific information for different types of services—housekeeping, spas, taxis, and the like—is uneven.
