While it was Richard Petty who recommended it, I did a little research because 
of Mark's question about why it costs so much.
The hard cover print edition is $41.83 on Amazon. 
Its shipping weight is 7.5 pounds.
It is 2112 pages.
This app says it contains everything that is in the print edition.
About 20 years ago, Oxford English Dictionary 2nd edition that was 21 print 
volumes, was about $900 in print, became available for $130 on a CD Rom.
Granted the OED 2nd edition had over six hundred thousand words, the cost of 
dictionaries have dropped dramatically.
What you are paying for is the linguistic expertees that goes into the research 
on the history and usage of the words.
According to Mr. Petty, the American Heritage app is quite accessible with 
VoiceOver.

Just my two cents worth.
Richard
