This app will allow you and your partner (or friend) to split bills, for example on a vacation.
Whenever you or they pay for something for both of you, put it the corresponding shared column. When you or they pay a private thing for each other, put it in the Mine or Yours column
Everything in the shared columns will be divided by 2, while the other columns will just be summed up.
In the lower rows, you will see the result, who owns how much to whom.
