This app has all the features you need when tracking spending for a group. You can enter any number of "friends", select who paid, who owed on the item and what their shares were. (For instance if you paid for a cabin rental for 3 nights, but some people only stayed for 2 of the nights.) In the end it sorts it all out and creates a scheme for everyone to pay what they owe and distribute amongst those that are owed... who owes what to whom.
The big problem though was that if I left the app and then re-entered it, the decimal places on the amounts got messed up and I could no longer enter amounts. Everything had to be entered at one time at the end of the trip and calculated immediately. Which still ended up being faster than using excel or paper and a calculator.
