Race Master Sail Timer + Speed

Everybody knows that catching the start is essential in sailing. Finally there is a great Sailing Watch available for the iPhone and it works great with the Apple Watch.
This app provides a timer, speed and course monitoring with unique features and unparalleled ease of use for sail racing. When you hear or see a race signal just press Gun! - You can adjust if it is a 5, 4 or 1 minute warning afterwards! And if it was just a loud noise from a flapping sail and not a race signal you can easily jump back to the previous timer.
It defaults to the standard ISAF 5,4,1,0 sequence but it can handle arbitrary countdown from 30 minutes down to 0
Now you can focus on other things like wind (directly in the app - simply configure your own favourite weather on the config page) and other boats potentially giving you yet another edge!
** Please read more on the info "i" page in the app **
You can enable GPS and get Speed over Ground (SOG) and Course over Ground (COG) presented next to the timer to help you keep track of wind and speed in the seconds before and after start. The Wind page shows a graph of COG and SOG which can help you track wind shifts.
It is designed to work on iPhone with or without Apple Watch and a lot of people seem to be using it with iPads as well.
TIP: On the Watch it is recommended that you (at least temporarily) activate Resume to Last Used App so that you just have to raise your wrist to get the time left:
Settings->General->Activate on Wrist Raise->Resume to: Last Used App
The iPhone application also contains a convenient reference to starting signals and customisable local weather information.
HealthKit integration:
The app provides limited HealthKit integration and can optionally start a Sailing Workout activity during race start.
