Online alarm clock for 6:41 am
Handing the ocean-pool watch to the next person at 6:41 am gives you a clear moment to step away while the water is still calm. Set the alarm for the agreed changeover, with 7:00 am as an easy reference point, so nobody has to keep checking the clock or wonder whether the handover time has passed.
Your swim can run longer than planned if the phone conserving power falls asleep before the alert is due. Keep the browser alarm visible and the phone awake, with enough charge for the full session; if the page is closed or the phone sleeps, the ocean-pool alarm will not sound and the next person may be left waiting. Set the volume before moving away, then confirm that the displayed alarm matches 6:41 am and that silent mode will not suppress it.
Early light around an outdoor pool can make a bright screen feel harsh against the dim surroundings. Lower the display brightness before leaving the phone in a dry, shaded spot, and use dark mode if the browser offers it. When checking the time, glance once rather than staring at the screen; by 7:00 am the growing daylight should make the display easier to read without turning the brightness back up.
Common questions
Why use a browser alarm instead of my phone's built-in one?
Mainly for reliability against silent mode, do-not-disturb, or a phone left charging out of earshot. It's a useful backup or a desk-based alternative, though it depends on this tab staying open rather than running in the background of your phone.
Is there a cost to use this?
No, it's free, with no sign-up and no limit on how many times you set it. It just needs the tab left open until the time you've chosen arrives.
Will the alarm still ring if I close the browser tab?
No. The alarm only runs while this tab stays open — closing it, or closing the browser entirely, stops the countdown before it can ring. Keep the tab open in the background if you need it to go off later.
Does the alarm work if my laptop goes to sleep?
Not reliably. If the device sleeps or the screen locks, the browser tab pauses along with it, so the alarm may not fire on time or at all. Adjust your power settings if you're relying on this over a longer stretch.
