Hipstamatic

One of my best friends shared with me this app and I'm absolutely in love with it.

Hipstamatic is a photography app that has different filters and options to get pictures with different look&feels.

Appstore App Description: Digital photography never looked so analog. The Hipstamatic brings back the look, feel, unpredictable beauty, and fun of plastic toy cameras of the past! The Hipstamatic keeps the the quirks of shooting old school but gives you the ability to swap lenses, film, and flash settings all with the swipe of a finger.

It's not free ($1,99 / 1,59€) but it's worth the price - you'll love the pictures! There are additional options and filters that you can buy, but the basics are very cool. 

Interesting & curious pictures guaranteed ;)
