Online alarm clock for 10:40 am
As you finish the last checks and leave for an emergency call-out, a 10:40 am alarm gives the crew a clear departure cue. It can mark the moment to stop updating notes, collect the radio and keys, and head to the vehicle without drifting towards 11:00 am. The alert keeps that transition tied to one exact time while everyone is wrapping up and moving out.
For a crew relying on this alarm, the phone or computer needs to remain awake until it sounds. If the phone goes to sleep before 10:40 am, the browser alarm may never ring, leaving the crew without its departure cue. Keeping the alarm visible and the sound turned up makes the setup easier to verify amid final checks. A separate radio-room reminder can provide backup when the browser cannot be left active.
Before leaving the station in the late morning, bright daylight outside can contrast sharply with a dim screen indoors. Raising the display only enough to read the alarm, then looking away while gathering equipment, reduces unnecessary screen time before departure. Positioning the screen away from window glare also makes the 10:40 am time easier to confirm at a glance without repeatedly bringing the phone close to your eyes.
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.
