This app is for the NYC yellow cab drivers.
The sole purpose of this app is to calculate your end shift receipt without having to do it manually.
Just fill in the values and press "Balance ".
Shake the device to clear out all the text fields.
A negative balance means you owe the owner that amount, and a positive balance means the owner owes you.
However the calculation does not include the 5% charge on credit card. You must make sure the 5% charge from credit card is already taken out before you plug it in on the app.
