WhaTip - Tip Wisely app for iPhone and iPad

WhaTip is the last tip app you will ever need.
WhaTip not only helps you quickly calculate a tip, it gives you the rules on tipping etiquette; all in an elegant design.
Conventional tip apps are basically rebranded, overly complicated calculators. They might tell you what 15% of your bill is, but dont give you guidance on what is actually expected or if you should even be tipping in the first place.
WhaTip takes the guesswork out of tipping.
