[nfbcs] Kindle app accessible?

[Tracy Carcione]

I was looking at books on Amazon today, and saw a blurb that said if I
didn't have a Kindle, I could download a free app and still use the Kindle
edition of the book.
Has anyone tried this app?  Was it accessible?  I'm loath to buy the
Kindle edition, then find out I can't read it.  On the other hand, it
would be great not to have to scan the book.
TIA.
