How to use the online timer
You start the countdown, leave the phone by your towel and move towards the rooftop pool, using seven seconds to settle at the edge before the swim begins. The brief gap keeps the launch separate from the tap on the screen, so you can face the lane, place your feet and focus on the first movement instead of holding the device.
As you take your position, the countdown tab may slip into the background because you opened another app or locked the screen. Some phones limit activity in a hidden tab, although the displayed time may catch up when it returns to view. Keep the browser visible if the sound marks your start, and avoid relying on a background alert when wind, water and rooftop noise could mask it.
For another start immediately afterwards, reset the countdown while walking back to the edge, then wait to begin it until everyone has cleared the lane. Repeating the same interval creates a consistent pause between touching the screen and pushing away. If the first attempt ends early, reset fully rather than restarting midway, so the next launch begins from the same point in the sequence.
Common questions
Should the rooftop pool start be slightly longer when the deck is wet?
Yes, allow extra time if reaching the edge requires slower steps or a careful turn. Keep this interval only when the phone is already beside your starting position and the path is clear.
What if the swim starts before the countdown finishes?
Let that attempt continue, then reset the countdown before the next launch. If early starts keep happening, place the phone closer or use a shorter interval that matches the actual movement to the pool edge.
