Free for PREMIUM members
Platform: Android (and others)
Google Hangouts (formerly Google Talk on mobile devices, and just a web-based video chatting service inside of Google+) has exploded in the past few years it's been around to take the lead among free, web-based and mobile video chat services.
Skype (Free), our previous favorite, is still a more than strong contender. Its user-base is still massive, it's cross-platform and cross-device, and it offers a wealth of tools that let you talk to people face-to-face or via IM, all on your Android phone. It's free to talk to other Skype members, and to video chat with them, but once you start calling landlines and talking to people's phones, you're looking at a few bucks, although nothing serious. However, the days of Skype being pre-installed on most people's Android phones as a video chat option are over, as more people move to Hangouts instead. That doesn't mean Skype isn't worth looking into—it just means it's another great option to have around in case Hangouts doesn't work for you for some reason, or you're talking to someone on the desktop who prefers to use it (or you're calling a friend's TV or something).
Fring (Free) is still a strong alternative to the big names. It supports group video chat, it's cross-platform, it allows you to register with your mobile phone number instead of forcing you into another account you may or may not use, and it also supports free texting, picture and video messaging, and cheap calls to landline phones. It's not quite as feature-packed as the others, but it does focus on the core basics.
Tango (Free) has grown exponentially since we last talked about it. It supports video calls to other Tango users on Android, iOS, Windows Phone, and Windows desktops. Tango lets you place regular voice calls and switch to video calls when you want to share something, and supports text, picture, and video sharing—not to mention audio sharing via Spotify. Video call quality could be better and doesn't seem to have improved terribly much as cameras have improved, but it's definitely serviceable.
Oovoo (Free) offered great video quality in our tests, but you do have to be an Oovoo user to really make the most from the app.
