Adobe, would you just pick a version of Photoshop for Android and stick with it? After unceremoniously dumping the conventional image editor Photoshop Touch last month and leaving us with the more Instagram-style Photoshop Express, Adobe has now released Photoshop Mix on the Play Store after a period of iOS exclusivity. This app is more powerful than Express, but less powerful than Touch, and attempts to bring a more manageable interface to phones.
In particular the new app has selection tools and basic layer functionality, meaning it's suitable for at least some advanced image editing functions beyond mere touch-ups and filters. (Those are included too, of course.) Manual color management and non-destructive editing round out the features. Surprisingly, the UI has some Material Design elements, at least on the project/file browser - Adobe usually does its own thing. The usual sharing and export options are included.
Photoshop Mix is a free download and can be accessed without owning any other Adobe software, though the app does insist that you log in to (or create) an Adobe ID to use it. Strangely, Mix is only available for download on phones - all of my tablets are showing as incompatible. The file has been uploaded to APK Mirror if you'd like to try your luck.
Adobe also released three Creative Suite tie-in apps, Brush CC, Color CC, And Shape CC. These are specific tools that are meant to create easily-imported brushes, color palates, and vector shapes (respectively) for Creative Cloud. They're not especially useful for anyone except graphic designers, though skilled hobbyists could probably have some fun with the vector tool in Shape CC.
