If you're looking for a SplitMyExpenses alternative, Cushion is worth a look. It can track bills, monitor what's been paid and what's due, and offer some useful budgeting advice. One interesting feature is a virtual Cushion card that you can use to make payments and that can help you establish a credit history. It can link to a calendar so you can schedule payments, and soon it'll be able to split bills.
Another SplitMyExpenses alternative is Fiskl, a multi-currency accounting tool for small businesses. That might sound more complicated than SplitMyExpenses, but it's actually got a lot of features, including invoicing, payments and automated bank synchronization. It can handle more than 170 currencies and integrates with hundreds of financial institutions, so it's a good tool for businesses with complex financial situations. Although it's designed for businesses, its multi-currency support and automated features can be useful for group expense tracking.
