Tango, a small California-based start-up, has released an app for the iPhone that offers free video calling over 3G and Wi-Fi networks. The app debuted in the App Store early this morning and works with the iPhone 4′s front-facing and rear cameras, as well as the older iPhone 3GS with its single rear-facing camera. A version of the app is also available for Android devices and calls can be made across platforms as well, allowing iPhone and Android phone users to make free video calls to each other using the Tango app.
Tango’s full feature list is as follows:
- Free video calling to your friends and family around the world, wherever you are
- Call between iPhone and other smartphones on 3G and Wi-Fi
- Populates Tango Contacts automatically from existing phone contact list
- Invite friends and others by e-mail or text
- Switch cameras and swap screens to show what is around you
- Move between video to audio and back to video
- Simple and easy to use
- Create an account in less than five seconds – New profile not required
You can find a list of all supported phones on Tango’s site. Video calls over a 3G network are data-intensive, so users on metered data plans should consider this to avoid racking up data overage charges. According to Tango’s FAQ, a video call uses about 4.5 MB of data per minute while calls made over a Wi-Fi network will not affect your cellular data usage, of course.
