This is a very easy to use app that does a few basic things that are key to sailboat racing very well. This app does what $500 freestanding gps racing gear/toys do with the exception of being waterproof ;-). Think Velocitek Pro Start for the iPhone, just add a waterproof case.
It has:
1. Count down clock, which can be easily adjusted to offical race countdown. It rounds to the nearest minute at the touch of a button.
2. Count down clock can automatically turn into a race time clock at the start.
3. The killer feature is the time and distance to the line based on your speed.
The developer responded to my question the same day, with a fix!
A+ App, with great support. Well done and well worth the nominal cost.
