ACTGratuity

From Houdah Software:

ACTGratuity 2.0 aims to be not only the most convenient tip calculator, but also the best looking one. ACTGratuity was first released the day the iTunes AppStore opened its doors. With version 2.0 it is back to reclaim its throne. ACTGratuity sports an all new interface and looks so cute you can't resist. Most importantly though, it is easy to use and yet loaded with all the features you need. The bill shows 4 rows: Check, Tax, Gratuity & Split. When a row is selected, you can key in values using the keypad. Otherwise it just displays current values. Usually you just need to key in the check amount. That row is selected by default. You enter the full check amount. ACTGratuity subtracts tax, computes gratuity and then splits the grand total by the number of guests. The 3 other rows show 2 values. When not selected, the value to the right is the computed value. The smaller value to the left is the value or percentage you have entered. Once you select a row, the configurable value moves to the right so you can key it in. Hint: The waiter's body acts as a vertical slider to adjust gratuity. Watch his facial expression change with the gratuity percentage.
