App Description

This is Gratt, your new handy app that helps you calculate the tip when dining at your favorite restaurant and bar. We’ve all been there. You have the best waiter or bartender and want to leave them a generous tip but doing math in your head is not your forte. No worries! Just fire up Gratt, tap in the bill subtotal, choose a tip percentage it automatically calculates the tip and bill total.

Want to split the bill with friends? Not a problem! Easily adjust the party count and the bill total will be auto adjusted for each person.

Thanks for using and sharing!
