I got this app to help remind me of basic 1st aid and CPR techniques. The learning sections are great for basic 1st aid that your average untrained person can use to be effective in an emergency situation.
If youre looking for an app to help you do surgery in the woods with a Swiss Army knife, this aint the app. But as a good refresher and reference app, I think its solid. I particularly like the test to make sure youre getting it. It aint Med school, but I personally like it!
