Thanks to the internet we now have the convenience to call our friends and family members for free no matter where they are. For those who own an iPhone and would like to call their loved ones from any part of the world where they have access to a wifi connection they can use Tango!

Tango is a brilliant free iPhone video calling service that connects people around the world with friends and family no matter where they are. A great thing about Tango is that it isn't just limited to iPhone, it can also be used on iPod Touch, iPad and all Android devices.

I have downloaded Tango on my iPhone and I honestly found it really helpful. It is an extremely easy to use app. All you have to do is register for a free account and start inviting your friends using the "invite" tab that looks like this.

Once this is done your friends can download Tango and start calling you for free. Anyone that is in your contact list and have Tango will be appeared right on the main page. Simply tap on the person's name you want to call and you're done. You can talk to them using speaker, turn on the cam to have an exciting video conference or simply use it as a phone.
