It's practice

It works for practicing the questions but there are some glitches like others have mentioned. There isn't any way to only answer the only questions that you haven't seen yet. So, you'll finish a set it will say you haven't completed 3 or 4 but then when you try to go back, there is no way of just going through those. (Either that or it doesn't count them/have them to answer.)
Also, I have come across questions where the response set or the explanation has been swapped between questions.
I was able to download to other devices, but it looks like it will make you pay for it. I held my breath and hit ok and then it popped up with a message that said I had already purchased it and downloaded it without charging. That said, it doesn't communicate between the two which question you have already completed so I have ended up just using my phone.

This app is ok/good. It reviews high yield facts but its questions seem to lack depth and challenge as compaed to U world. The same goes for the answer explanations in the app- but that may not be necessarily bad if you like straight forward q and a. Images need to be in color or improved to be morerepresentative. Despite this, the full app provides 986 questions which are accessible without an internet connection, which is a plus if you are not in a wifi hot spot and also because the shear volume of questions will provide breadth of topic coverage. The interface is ok all though if you zoom in, the text is not wapped to the window. Also, the swipe feature in the browse mode seems to have been fixxed. If you have some extra money on the side you shouldtry out this app to have a quick but basic q and a set at your finger tips otherwise try out the free version and see if it fits your taste.

Questions are decent for reviewing high yield first aid info. Certainly some dumb questions though. Biggest prob is browse mode. Swipe to go to the next question...then boom you just skipped 3 questions inadvertently and finished the quiz. Now you can look at the quiz with every answer choice and explanation exposed, bummer you didn't get a chance to actually practice those last three questions. This gets very annoying/frustrating, and board prep is brutal enough without halfassed programming.
