Good app for language exchanges
At first I wasnt too impressed with this app, but more recently they added a group option where many people can chat together and meet depending on the language of the group. Im finding this a good way to meet people and to practice various languages. Its still not perfect, but it looks like the developers are committed to making improvements . This app has never crashed on me, but I have a 4gs so I dont know how it works on older iPhones.
