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.
