Sailing things right

Dunno if it will really help anyone or bring any money to me, but I'm really happy with the outcome.

This is an app I've decided to spend some tokens on that's aiming to provide a very convenient and quick aid to identify the vessel's signaling for those like me who are too lazy to learn the full COLREG signaling system. :)

Also it will help with figures signaling during the day and buoy meaning identification.

Need help from you: how much would you pay for such app? I'm looking forward to set about $5 price as a single lifetime payment.
