ELFSH alows you to share costs. It keeps track of a total for every person in a group. If you want to buy something "on the group" you can enter it in ELFSH and the price will be split over every participant. After some time you can chose to pay the differences.
ELFSH alows coordinating eating togher. If you live with a lot of people there is always competition for the kitchen, and if you do cook for multiple people coordinating every day is a pain. ELFSH alows easy coordination even for large (10+ people) groups. Simply set yourself as "E" if you want to eat and "K" if you can cook. No need to have an anoying chat conversation each and every day.
Great and easy to use tool. It’s easy to invite others and the only thing needed to access an “event“ (thing for which costs are shared) is a link. No registration required.
The only thing I miss is proper multi-currency support. The paid “Super Kitty” includes multi-currency support of some sort, but it does the conversion for each transaction at an automatically looked up rate. This is not sensible if you pay in cash (then the rate is whatever you’ve got when exchanging the money). Even if you pay by card the rate may vary (eg. additionial fees, …). I ended up converting the amounts manually with the average exchange rate we’ve got.
