For many, Instagram already offers the vintage feel and nostalgia of old photos. So what use is Polaroid’s Polamatic app? Well, Polamatic has all the filters, borders and captions that defined Polaroid’s iconic product, allowing you to choose from 24 different fonts and text customization options.

Waze (iOS, Andoird)

Recently the subject of a bidding war between Facebook and Google, Waze was eventually snapped up by Google for $1bn (Yes, you read that correctly). Essentially a social-sat-nav app, Waze, like Wikipedia, relies on user input to update map locations - restaurants, bars, venues, etc. - to make digital maps more accurate and more integrated with other social media platforms and other users. It also allows user to provide real-time, up-to-date traffic warnings. This app could definitely be a game-changer. www.waze.com
