It's a great effort as well it is very helpful to us. There are some mistakes in few words. Hoping to see them correct soon. Mistake I observed is rule 7 (d)(i)...it should be bearing instead of hearing.

There is a mistake in Rule-9 5th paragraph. There it is written that the vessel intending to overtake shall indicate signal proscribed in rule 34c(1) but in IMO publication it's written that vessel intending to overtake shall indicate her intentions by sounding appropriate sound signal proscribed in rule 34c(1).

The best app I've seen, the words are easy to understand. Hope you will add more feature like quick quiz in the future.
