Online alarm clock for 4:47 am
As you hand the unloading over to the next crew, set the 4:47 am alarm so the catch keeps moving across the wharf before the fish market opens. It gives the incoming shift a clear cue while you finish the handover, check the last crates and explain what remains. With 5:00 am approaching, everyone can work from the same changeover point rather than relying on a hurried shout across the deck.
The sound should suit the working wharf around you. A softer tone may be enough when the replacement crew is nearby and watching the unload; a persistent tone makes more sense when engines, winches or refrigeration units could cover it. Check the volume before putting the phone somewhere secure and within hearing range. Keep the browser running and the phone awake, because otherwise the alarm cannot sound and the catch handover could lose its timing.
Before leaving the wharf at this hour, allow for the actual drive rather than assuming empty roads make every trip quick. Coastal fog, wildlife, roadworks and slow access roads near the harbour can add minutes even before early commuter traffic begins. Note how long the route usually takes around 4:47 am, then leave a small buffer for securing gear, finding keys and getting the ute onto the main road.
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.
