Tip Calculator is a simple app to help determine the amount of a tip that you want to leave. You are even able to enter discount you may have used.

Tip Calculator allows you to base the tip on either the Sub-Total of the bill, on the Pre-Tax amount, or on the Total amount. This way you don't have to tip based on the amount that you give to the government.

Use the green check boxes to determine which method you would like to tip on. Depending on the box you choose, you will be able to enter different values.

As you type in the amounts, you will see the tip amount and the total bill amount. You then have the option to round up the tip amount so that the bill total will be a whole dollar amount.

You then can save an informal copy of your receipt/tip. Click the 'Save' button in the upper right corner of the screen and then you are able to identify where you went. The map will show your current location. Click the 'Save' button and your receipt/tip will be saved and available to be seen from the 'View Tips' button.

This app uses GPS mapping to determine your current location. Using the GPS can drain your devices battery.
