Tippity Do Da is designed to be fun, fast, and easy to calculate your tip. Automatically SCAN the receipt's bill amount, calculate the tip, and the give you the total in a single step! Generates a REAL receipt that is automatically saved to history or you can email a copy of the receipt. Email a copy to a friend after splitting the bill or email a copy for an expense report! Remembers the location of the restaurant and will automatically put the name you entered on to the receipt the next time you return to the restaurant. If you prefer to enter the bill amount manually, the ATM style input makes entering it a snap! Touch any part of the receipt you want to modify and Tippity Do Da will display the appropriate options to do things like add the restaurant name, round the tip, round the total or split the check! Browse your old receipts and email a copy of the receipts to yourself or anyone else, anytime you have a need! Personalize Tippity Do Da by selecting a theme for the background and buttons.
