In its continuous effort to develop the best mobile video calling app for iOS and Android devices, popular service fring has announced that they’ll soon launch a private beta to pilot a group video calling feature that will be available on fring later this year. The beta program is open to Android and iOS users, and it’s been demoed in a video published by the developers in a blog post.

The new fring will allow you to easily browse the buddy list and pick a contact to add to a group call. The functionality apparently supports up to 4 simultaneous conversations and works both on WiFi and 3G. Once a person has been added to the group call, you can go back to the main screen and keep adding buddies until the limit is reached. As soon as you tap on a contact’s name, fring will initiate the call – meaning you don’t have to wait for all connections to go through at the same time. You can see how it works in the video below.

The dev team is putting the finishing touches on a super cool new service: free, mobile Group Video Calls. We are having too much fun with it already, and want to get some feedback from users ahead of public launch on Android & iPhone.

Of course, this is super-exciting as it’s the 1st time the world will get to enjoy free Group Video calls.

Fring for iPhone was recently updated to include the possibility to switch between cameras, buy credit through in-app purchases and enjoy fullscreen video calling with a “Dynamic Video Quality” the company has heavily promoted on mobile devices. Fring for iPhone is available for free in the App Store.
