Back in September, GeekTech had posted a demo of video calling through the Tango app on a HTC Titan. One of the major features that windows phone 7.5 will bring to the phone is video calling support. However the app wasn’t available for download then. At last, a video chat app for Windows Phone is now live in the marketplace.

Tango allows you to make free phone calls and free video calls over 3G, 4G, and Wi-Fi. Make calls to any other person who has Tango installed on their smartphone, tablet or PC. Start a Tango call with just voice, and easily move into a video call when you have something to share. It’s easy to use, it’s fun, and it works.

Tango Features:
• Free calls between Windows Phone, Android and iOS phones and tablets, and PCs
• Save money with free international calls to other Tango members
• Start a phone call with Tango and switch to a video call when you have something to show by tapping the camera icon
• We automatically find the friends that already have Tango
• No log in and password – create an account in less than five seconds
• Invite your friends by Text and Email
• Simple and easy to use

You can download this free app HERE.
