ColorSplash has been around for a while, but it’s still one of the most popular apps available today. The app converts any image that’s imported from your library to black and white giving you control over which details retain their color. Create your next masterpiece in landscape or portrait mode with four different brushes (transparent, opaque, hard or soft edged) and immediately share upon completion to Facebook, Twitter or Flickr. Video tutorials are embedded within the app if you get stuck along the way. Not too shabby for $2.
