Great learning tool

Brilliant as a reference guide, could do with a lot more quizzes though... you need to be able to practice and the current quiz just isn’t enough. My only complaint though!!

Good app but quiz needs more

As other people have said it's one of the best apps there is for OOW and things but the quiz majorly lacks in substance.

Other wise thanks for a decent app.

Very good app for boaters

There is not a lot apps on the market for boaters or beginners. This app is very good for beginners to learn offine for a short time at the airplane l, tube or wherever. On the sea useful for newbies to quick check. Good job.
