I'm disappointed at the number of spelling and grammatical errors I've found so far. This is in addition to missing rationales and incorrect answers being given. For a $12 app I expect a certain level of polish that just isn't there yet, the app feels unfinished almost as if it was rushed to market. I found errors in every review section and in many of the practice exams. Which is too bad as I think it has great potential as a review tool for paramedics. I hope that the authors continue to develop it and work to fix the errors in the app. Till they do that I can't recommend that anyone pays $12 for it, perhaps when it is complete it will be worth that much money. As an aside, I'm a paramedic in Ontario and would love it if some Canadian EMS info made it into a future version.
