Fring is the sole mobile-only video conferencing tool in this roundup, making this system a nice choice for those who eschew computers altogether. The system supports video chats with up to four simultaneous talkers, arranged in a convenient grid on the screen of your smart phone or tablet. There’s not much in the way of extra features—this is really just a fun way for multiple people to chit-chat while seeing each other—but considering the casual design of the app, perhaps it doesn’t need them. A for-fee international landline calling system, a la Skype, is also available.
Platforms: iOS, Android, Nokia
