Hey there! We definitely want to keep improving our user interface, but I’m closing this suggestion for now because it’s not very specific. If you have any particular thoughts on how we should improve Splitwise, let me know and I’d be happy to pass them on!

Unfortunately, we also don’t have any plans to make a BlackBerry app right now – we’re a very small company (just two engineers), so web, iPhone, and Android is about as much as we can handle. However, if you know any BlackBerry developers, they’d be welcome to build their own Splitwise app using our public API: http://dev.splitwise.com. Sorry for the inconvenience!
