Yep, that's the way to go. I have the app on two 10" devices and use this tablet to tripod clamp. Too much weight for the shoe mount adapter that came with the clamp. Tablets and apps provide much more versatility than just a dedicated monitor, wouldn't you think? Helicon is another free dslr controller with the addition of having the capability to automate focus stacking. With an android and a DSLR, the world is your oyster!
