During a regatta or a race, you can start a countdown (timer). The countdown feature can be activated or hidden from the Settings page within the app on the Apple Watch, or by clicking on the "05:00" button on the map or choosing from the 3 dots menu, in the iPhone app.
Note: you can activate the count with the Action Button of the Apple Watch Ultra. When pressed, it will first start the Countdown, then it will do the "Sync -", then, after the normal tracking is started, will perform the Side Buttons action.
The Countdown will sound and vibrate at 4 minutes, 1 minute, 30 seconds, and for the last 10 seconds. Adjust the minute amount using the '+'/'-' buttons, also if the countdown started, to sync with the real countdown. On Apple Watch, use the Crown to adjust this value (it works only if you have disabled the 'Crown to start' switch, from the Settings page).
Press on Sync + to reset the value to the upper minute. Press on Sync - to reset the value to the lower minute.
At the end of the countdown, the navigation will start automatically.
The navigation can be manually started during a countdown.
For Apple watch Utra: pressing the Action button, if Countdown is set, will start the Countdown and, if you keep pressing, will do the 'Sync -', till starting.
Waterspeed saves the countdown activity and will report in cyan color on the detail page, but if you stop the countdown before it ends, the track will not be saved.
Please note: Countdown on Apple Watch is free, on iPhone is available only if you subscribed to Waterspeed Pro (see the related article for details).
