Don:
On my Android phone or tablet I just touch on the TFR and up pops all the info I need in a box at the bottom of the screen.
Example: The Disneyland TFR says "Now active for security reasons as of 10/27/14. Alt: Surface to 3000 AGL"
We have many fires here and the TFR tells when it is active, inactive and how high.
