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. Summary of Features: * Simply the best countdown timer ever if you ask us :) * Really good compass! * Most of the feature work on Watch and iPhone. Watch Series 2 needed for GPS without iPhone nearby. * Current Course and Speed Over Ground based on GPS * GPS based distance to line (still being tuned but works - within limits of GPS accuracy) * Speed up / Slow down estimate for time to get to line * History plot of Course and Speed Over Ground that allow you to track wind shifts * Prevalent headings - advanced formula lists common headings to help identify windshifts * Man Over Board function - it shows time, distance and compass bearing to the location the button was pressed (NOTE: intended as a secondary non life critical aid only) * ISAF Race Signals reference - to help settle what that strange flag shown on the race committee means before the race starts... * Choice of Magnetic or True course indication * Lock function to prevent unwanted changes NOTE: Please check the "i" page in the app for more info This app offers 2 in app subscriptions to 1) support continued development and 2) to enable certain features: • Payment will be charged to iTunes Account at confirmation of purchase • Subscription automatically renews unless auto-renew is turned off at least 24-hours before the end of the current period • Account will be charged for renewal within 24-hours prior to the end of the current period, and identify the cost of the renewal • Subscriptions may be managed by the user and auto-renewal may be turned off by going to the user's Account Settings after purchase • Any unused portion of a free trial period, if offered, will be forfeited when the user purchases a subscription to that publication, where applicable Please review our Terms of Service: http://www.kewlanu.com/tos DISCLAIMER: If you enable the GPS feature the app runs in the background for a limited time before it disables GPS.
