Bill Pain

Bill Pain is the App to facilitate the way people calculates how much must be paid by each one. It is useful when you are with family or friends in a restaurant or bar, because some times you are alone, others come with children, other takes coffee or desert, another don't, etc.
Groups are defined easy and quickly. Which one takes coffee, desert, have children…
This App avoid the need to use a calculator and do the accounting to see how much should pay everyone.

Exemple 1: Dinner for 4 groups:
1. Couple 1: with one kid.
2. Couple 2: with 3 children.
3. Couple 3: no kids.
4. One single person.
Total amount: $ 217.90. It doesn't matter the amount of deserts or coffees.
Having in mind that a kid pays half of the adult, we have 9 people (7+4*0.5). Each adult must pay $ 24.21, and each kid the half. For this example the App should show these results (rounded to $ 0.5):

1. Group 1: $ 61
2. Group 2: $ 85
3. Group 3: $ 48.50
4. Group 4: $ 24.50

The App permits rounding up and down. Excess could be for tips.

Arguments at the time of paying the "Bill Pain" have finished.
