Fring is another free VoIP and video calling service that offers voice and video calling features. Although the service may not be as popular as Skype, it does offer video calling from Android tablets. The Fring app also offers a group video chat, which is a really nice feature that is only available in a few video chat services. The interface of the Fring app is simple and playful, as shown to the right and in Figure 16–5.
