Tip On Discount

Tip On Discount is a free Android tip calculator with NO ADS and NO REQUIRED PERMISSIONS.

To calculate your tip, in most cases, all you need to do is enter the bill total. TOD will subtract the tax and calculate the tip for you. You don't even have to press a "calculate" button. The math is performed on the fly as you type.

TOD can split a bill between multiple parties and round each share to any amount you like. Say you're out to a nice dinner with friends: When the bill comes, someone looks it over and says, "it's $103 a couple". If you don't have single bills, what kind of a tip are you leaving if you all throw in $105? If you don't have fives, is $110 too much or should you wait for change? Maybe your server was really great and you decide to pay with twenties. How good should you feel about yourself for leaving such a great tip? This app tells you with one button. (In case you're curious, the last scenario works out to about a 36% tip in a state with 7% tax--you're really swell!)

For techies: The code makes full use of JUnit test cases and Android JUnit test cases. Since it is a relatively small application, it should be useful to those who want to learn Android development and automated unit testing.
