Snapseed is a full-featured photo editing client for your iDevice. You are able to use Auto Correct to adjust your photos with a single tap, tweak your photo with Tune Image, and or enhance areas/objects in your photos with Selective Adjust. Snapseed also provides a bunch of innovative filters (i.e. Drama, Black & White, Vintage, etc.) and Image Borders so you can add some personality to your photos. The app also provides the ability to share your finished photos through email, Instagram, Facebook, Flickr, and Twitter.
Snapseed is indeed a solid app, but I find the price too high given the abundance of other similar apps in this genre. I personally got this app when it was discounted, so I suggest the same.
