I know this sounds like a sponsored advert but I love Snapseed. It's a great photo app I have on my iPhone. It's got more controls than Instagram and is really easy to use. I like it much more than Adobe Photoshop's app which is great news as I have a real problem with Adobe. In my experience they have the worst customer service I've ever encountered and any competition that threatens to break their stranglehold on the market of digital image manipulation is good news. Above is a picture I took through the window of a plane over NYC last week and worked on with Snapseed. Below is the original picture.
