Finally Adobe released a free version of Photoshop, even though the features are basic, its a great move from Adobe to give this Android app free of cost to its users!
With Adobe Photoshop Express, you can edit and share photos virtually anywhere. This is a touch based app, you can crop, rotate, adjust color, and add artistic effects with your fingers! Also you can access your photos from your free Photoshop.com account. There are options to share the photos with your friends and family via social networks such as Facebook.
