Please do NOT discontinue Photoshop touch. All the other new apps you have are crap. I have tried Photoshop Mix which is a joke compared to Photoshop Touch. This was my main app to use on the iPad. None of the other apps support multiple layers and photo masking. BIG MISTAKE to discontinue this app.
Unfortunately, they discontinued PS Touch over a month ago. The forthcoming "Project Rigel" is supposed to help fill in some of the gaps left by PS Touch but we won't know anything until around the fall.
