At Camera Bits, we certainly understand the power of including a tablet in a photography workflow. Photo Mechanic® does work on Windows touch tablets. However, there is not currently a version of Photo Mechanic for iOS or Android devices, nor have we announced one. Keep an eye on our Twitter and Facebook feeds to be the first to know if this situation changes.
By the way, leaving a comment in our Feature Requests forum helps us gauge the need for various features and products. We'd love to hear from you there.
