Photoshop Touch is the very popular version of Adobe's photo editing program built specifically for mobile devices in mind. Unfortunately, the app was only available for tablets, but now Adobe has managed to squeeze it onto phones.
Adobe announced that Photoshop Touch is now available on the iPhone (4S and 5 only) and Android (4.0 and up only) smartphones. The app costs $4.99, and features a new UI that's built specifically for smartphones. That being said, it features almost all of the same features and toolsets from the tablet app:
Much like the tablet version, Photoshop Touch on the phone has core Photoshop features like layers, advanced selections tools, adjustments and filters. We also packed in features exclusive to Photoshop Touch, like Scribble Selection for high-precision selections using only your finger, and Camera Fill for real-time creative blending of your camera feed with layers. This app features the same creative filters as the tablet version, like Color Drops and Acrylic Paint, and also a new Ripple filter.
Photoshop Touch also takes advantage of Adobe's Creative Cloud to allow creators to share projects across different devices:
With Photoshop Touch and the Adobe Creative Cloud, I can start a project on my phone, continue it on my tablet, and polish it off at my desk in Photoshop CS6. Photoshop Touch will automatically keep my projects in sync on each device, at the full resolution and with all the layers intact. This capability is available to every customer with a free Creative Cloud account. There is no paid subscription requirement for syncing.
