Here's an example
Jack, Jane and John go on a skiing weekend together. Jack pays for everyones' ski-hire;
Jane pays the hotel and lends money to John; John pays for dinner
Now who owes what?
Jack creates a kitty on Kittysplit and adds his own expenses one at a time.
Sharing the kitty
Once he's finished, Jack sends an email with a link to the kitty. John and Jane click
on the link and can enter what they paid – no signup required!
Everyone can then see how much they owe. They can settle up and remain best friends forever.
