Great!
I am a Canadian emergency physician. This app has been my go to for a long time now. It is like having a friendly, knowledgeable, and most importantly surly, ID doc available at all times to answer my dumbest questions. It is well worth more than the asking price and I highly recommend it to all of my friends and colleagues.
There should be more apps like this around.
