4. Photoshop Touch
If you are the kind of person who spends a lot of time trying to pick out the perfect picture than Photoshop Touch is for you. If you prefer spending more time with the editing tools to compliment your high-resolution camera then Photoshop Touch should become your favorite photo app. Developed by Adobe, Photoshop Touch is the mini mobile version of their famous Adobe Photoshop. The bright side, however, is that, Photoshop Touch is far more user-friendly than the desktop version. It has been praised by users for having a simpler user interface. There are very few apps in the market which can deal with the high resolution of the iPhone 6. The best part is that the app is free for download from the Apple App store. It is really the app for a careful photographic artist.
