The app is quiet handy for being able to quiz yourself on the go. That said, it only offers quizzes (no actual study material).
The quizzes are structured decent enough, you can choose which sections you wish to see at any given time. That said, some of the sections do not provide you with the full question, so you’re doomed to guess on those questions. Along with this, there’s naturally a set number of questions available so you’re at risk of memorizing the questions rather than improving your knowledge in that specific section. Obviously, that isn’t the apps fault, but you should ensure this isn't your only study material.
Overall, the mechanics of the app work nicely. But frankly it’s not worth $9.99, in my opinion. For a bit more you can order an AFOQT study book that teaches you and offers quizzes. This app would be greatly improved if they had study material/instructional portions that you can look at rather than just quizzes. If anyone reads this, thanks for your time and best of luck on the AFOQT!
