So let's say you're not a big fan of the stock background and how the buttons look. This program is also completely customizable. Photos, videos, sharing locations, and much, much more make this program a must-have for anyone looking to stay in touch with their friends and family from a distance. It basically functions as a video chat program with built-in peer-to-peer capabilities, allowing you to exchange files and emojis and other data as well. Much like other video chat programs on the market today, Viber uses a VOIP system that allows you to take advantage of your 3G (or higher) internet to text message, voice call, and video call with anyone else who has the program. Although this classifies more as a program and not strictly an app, due to its functionality, you basically download and operate this in the same way you would any other Android app for a qualified OS. The download operation here seems fairly straightforward too. Skype is a huge file, almost 100MB, and thus isn't very mobile-friendly at all.

What exactly are we speaking about here? For starters, this is a free program that only takes up a few MBs, and that's why over 6 million people have downloaded it to date. A program like Viber, for instance, has a much smaller footprint while still giving you all the features you'd find on a much larger program like Skype.

This is why video chat programs for mobile operating systems are in much more demand for Android users. Though when you break them all down for the PC, they're all basically the same in regards of using a lot of power, eating a lot of space, and having some serious load issues. And if we're being totally honest, Skype is only one of a long list of video chat programs that you can download. PC users have known about Skype for a long time and what they can get with that program. Sort of like Skype without the huge file size, RAM-hungry operation and long load times, Viber is one of the newest peer-to-peer video and voice chat programs out there today for the Android OS.
