not worth $8. There is better for free out there.

I brought this app with high expectations of the quiz feature. I was hugely disappointed. Each quiz only consists of 10 questions and its just the same questions each time so the second time doing the quiz you already know all the answers. I mean cmon there are 26letters in the alphabet plus numbers and subs! How hard would it be to add some more questions and a randomizer??!!
Also the signal flag meanings have been shortened or are incorrect.
Im studying for a captains ticket I would like to learn the terminology as it states in the international code of signals.
App is nicely presented but needs more work. I will change my review when this has been updated.
