Indispensable for sailing: I love Waterspeed – Waterspeed Sailing, Wing, Wind Review

This is a great app for sailing! I use it to review my routes, track my speed and heartrate, and playback the entire itinerary on my iPad. If it weren't for Waterspeed, I'd have to buy a $500 electronic compass for my dinghy. Instead, I pay $3 per month for this app during the sailing season and then pause my subscription over the winter.
