Fring is a big money saver. You can chat, and call from your phone all through this one application. This way you don’t have to worry about your phone contract. You can IM on GoogleTalk, AIM, Yahoo, and view Twitter messages among other services. You can call from this application. Essentially this is just a way to keep all of your social media and communication connected and in one place.
Personally I find this really distracting. If you hook up your Facebook and Twitter your stream of statuses and Tweets gets hard to keep track of. Also, they recently took away the video chat capability when Skype split from them. It’s not worth the capabilities you get. Actually, if you don’t continually check on your stream with Fring you end up having a ton of messages built up depending on how many of your friends Tweet and Facebook. Honestly, I don’t really know why you’d want this unless you’re planning on only using a few applications. The Facebook and Twitter applications themselves are easier to use than this, so there’s not really a good reason why you’d want to use this.
