Online alarm clock for 9:05 pm
Pack your towel, goggles and warm layer before setting an alarm for 9:05 pm, so your evening swim at the ocean pool has a clear finish time before you leave home. With 55 minutes until 10:00 pm, you can use the alarm as a firm cue to climb out, rinse off and gather your gear rather than checking the clock between laps.
Your ocean-pool session depends on the browser remaining open and your phone staying awake: if you close the browser or the phone goes to sleep, the alarm may not sound for the end of your swim. Keep the alarm page active, turn the volume up enough to hear it from the pool edge, and check that silent mode will not suppress the alert. A separate phone alarm is sensible if missing 9:05 pm would affect transport or access to the change rooms.
Poolside noise can shift quickly late in the evening as families leave, lap swimmers thin out and nearby traffic becomes more noticeable. Put the phone close to your towel but safely away from splashes, with the speaker facing outward rather than buried under clothing. At 9:05 pm, an alert that seemed loud during setup may blend into pumps, waves or conversation, so test its sound against the actual background before entering the water.
Common questions
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.
Do I need to create an account or download anything?
No, there's nothing to sign up for and nothing to install. Pick a time and a sound, press Start, and it runs entirely in this browser tab.
