Curious what apps, if any, people are using out on the race course? I've been plugging waypoints into my Navionics app and using the GPS for distance and rough time to the mark. I find it hard to take a lot of time to look thoroughly at my iPad, so I like the simple Navionics screen and layout for quick glances. Is anyone else using Navionics? Or any other useful apps? I also downloaded iRegatta but haven't used it enough to know for sure if it's worth keeping.
