Instagram, Hipstamatic and PicPlz are some of the examples of mobile apps that can bring an analogue feel to a digital photo, making it more aesthetically pleasing. Along with this, you can also get a variety of filters and color hues that can change how a photo looks.

#2: Front-facing Camera Apps

The feature of having just one camera is a thing of the past, and thanks to devices such as the Motorola Xoom or the iPad 2, several options for video and photo apps have opened up. Whether this extra camera allows one to take his photo as an avatar or for video chat support, this will lead to app developers paying attention to camera attention more closely.

#3: Access to Tumblr, Twitter, Flickr, Facebook and Foursquare
