It is definitely a good app. In fact, there isnt anything necessarily bad about it. It has more than just questions. Flash cards, scenarios, and other tools are very helpful.
The only reason why I give it a 4/5 is because I always look for something that can be improved to make it a "perfect" app. I think that the questions need to be questions from the national registry. The questions that they have are good, but they do not help prepare you for how the national registry is structured. This is a key thing for being able to pass. The questions they have definitely help you learn the information, but maybe there needs to be another section with NR questions.
