I am not an Apple fan, so I waited for the Android version. I run it on a 7" Galaxy Tab 2, and I have had no problems with it.
If I am concerned about battery life, I power the tab from a "mini-gorilla", (with the appropriate cable).
I mainly use it for planning on the ground and for backup in the air.

Check the Android version on your device vs the website - SD only runs on recent versions.
