A free app for Android, by UOL (Universo Online).

This free application for Android devices will let you make video calls to your friends and family on your smartphone or tablet. It’s the best way to stay in touch with your friends and family, no matter if they’re far away or right next to you.

When you start the application, you’ll see a list of people who are online right now. You can choose to talk to a random person or pick someone from a list of your friends or family. You can also choose to create a group chat with up to nine people.

Video calls are free and there are no subscription fees. The only thing you’ll have to pay for is the data usage.
