Hi Jon - I copied this answer from another discussion in this forum (Adobe Shape for Android?):
We just posted a beta version of Adobe Shape for Android. The beta is open to everyone. We'd love to hear your feedback. Here's how to get it:
(1) Visit the Google+ community for Adobe Android Apps - Community - Google+
(2) Request to join. (we will try to approve your request within 24 hours)
(3) After you join, you will find links to Adobe Color, Shape, and Brush on Google Play.
(4) Install the apps, give them a try, and let us know how they work for you by adding a comment to the community.
Thanks for your help!
and now some of these apps are officially out on the play store (photoshop mix, color, shape and brush)
Sadly, absolutely none of the apps are available for Android tablets. Given that my Android phone screen is tiny I'd been looking forward to, and wholly relying upon, the apps being compatible with tablet devices. Gutted
