Tango is for two and this the principle on which the developers of the application worked in order to create this freeware product. Video calls are still expensive but there are alternatives in the market, this tool being one of the best. There is the possibility to install it on PC, but users can also download the same tool for various devices that feature Android and iOS operating systems. This way, someone at home can keep in touch with friends that travel. The only requirement in order to initiate a video call is that both users have Tango installed, either on the computer or on a device.

Accounts can be created within seconds and afterwards, not only video calls can be performed. Users can also start media sharing sessions and send files to the other participants. Tango can be integrated with Facebook and this is useful in order to find friends that also use this application. It is recommended to use a Wi-Fi connection as this will allow people to benefit from the highest quality video stream, which can be displayed at high definition resolutions, if the device or the computer supports this feature.

Various animations can be imported and they can be used in order to personalize a video call. During the same call, video game challenges can be initiated and users will be able to compare their scores afterwards. A special photo gallery will be created by Tango and users can easily manage it in order to add notes to pictures and videos. Photo filters and a few other effects are also available for use within the application and they are of great use if one does not want to send a simple stock photo. Moreover, the app does not conflict with the plan provided by a telecommunications carrier.
