Once in a while an app that does an really nice job comes along and for me it is a must-have. Once such is Waterlogue which produces watercolor-like images from a user's photographs.

I had a look at this originally in December 2013 and use it fairly often. At that time, the price was shown as $3.99.

The app has just appeared (again) in the Best New Apps section of the iTunes store here and Waterlogue is now shown as $2.99.

Highly recommended.
