This is the photoshop express app on my iphone. It is a very basic mobile editing app by photoshop. It has filters, frames and basic effects and adjustments such as crop and red eye remover. The app that I use is the free version, there is another version that has more effects and filters available but you have to pay for it. Here are some screenshots that I took from my phone to show some of the features of the app:

When I have finished editing a picture it then gives me the option to share it through various forms of social media based on the apps I already have installed on my phone such as facebook, flickr, tumblr and email. Alternatively I can just save it to my camera roll to share at a later date.
