Gratuity Guide

Description

Gratuity Guide is a smart tip calculator. It does the basic tip calculating like other tip calculators, but also uses your location to determine the sales tax for your bill. This enables you to base the tip on the bill's subtotal instead of the total bill. Gratuity Guide then does all the math for you. Adjust the tip %, split the bill among different numbers of people, round up or down, it's all there.

Gratuity Guide was designed to do a simple job simply yet have the flexibility to handle more complex tipping scenarios. In the settings, you can specify an extra "misc" line item for the bill; use this to include things like a delivery charge, "healthy San Francisco", or whatever you need.
