"In app purchases"
ATLS is a wonderful and intense program. The sign up cost is over 1K which includes the paper book and a link to this app. The app is bare bones. I think it should be free to those who certify because the paper book is big and bulky. This app could be very useful in the field. For what I was able to access "for free" its quite helpful. I would have rated higher if it were not the big additional cost.
