I love it!!

Excellent questions, excellent format. I like the instant feedback and references right after the answers. I used the hard copy ACCP-SEEK for years and think this is superior. It is not cheap, but cost the same as the hard copy. My iPad app has not crashed once. I look forward to more editions in sleep as well as pulm & CC.
