Today Adobe has released Photoshop Touch for both iPhone and Android devices. The app contains almost all the features of the tablet version such as adjustments, layers, advanced selection tools and filters like Color Drops, Acrylic Paint and a new one called Ripple. In this version you'll also get exclusive features to Photoshop Touch such as Scribble Selection feature for high-precision selection using only your fingers and Camera Fill, which Adobe says, is for real-time creative blending of your camera feed with layers.
Photoshop Touch also allows you to start editing or creating on your phone and continue where you left on your tablet, and then move to your desktop computer if you have Photoshop CS6. Photoshop Touch automatically keeps your creations in sync across devices with everything intact. This feature requires a Creative Cloud account with Adobe, which is free and requires no subscription.
