STBCalc (Split The Bill Calculator) is an application for iPhone / iPod touch. It is designed to be used when you split the bill equally at a restaurant, bar, etc. You can easily calculate a payment amount per person by setting total amount of money and number of persons.
Each payments can be restricted to amounts in increments of $1.00, $5.00, $10.00.
First, set the total amount of money.
Then, you can set number of persons by tapping a row. If you tap the same row already selected, you can set an amount per person. After you change number of persons, each payment amount will be calculated automatically. When there are multiple rows, changing number or payment per person will affect the payment amount of the bottom row (above the total row) to bring the sum of rows close to original amount.
Sum of the each row and the difference to the original amount are displayed in the TOTAL row.
If you want to delete a row, sweep the row. Then tap the Delete button.
If you tap the mail button, an actionsheet will appear. After you select 'Send an email', a mail composer will bring to front on iPhone OS 3.0 or later. If you use prior to iPhone OS 3.0, STBCalc will quit then Mail application will be started.
