Online alarm clock for 7:40 pm
As you finish your evening run beside the river, set the alarm for 7:40 pm so there is a clear moment to turn off the path and head home. That leaves the rest of the evening intact, with 8:00 pm close enough to serve as a natural boundary between exercise and whatever comes next. If you leave the browser alarm behind or let your phone sleep, it may not sound to end the river run, so keep the page active until you are back.
The sound that finishes a riverside run should suit where you expect to hear it. A softer tone can be enough when the phone is in an armband or pocket and the path is quiet; a more persistent tone makes sense near traffic, cyclists, conversation or rushing water. Check the phone volume before setting out, then choose a tone you can recognise without making it unnecessarily harsh for people nearby.
Arriving home around 7:40 pm can affect anyone already settling into the evening. Keep the phone with you rather than leaving the alarm to ring in a shared room, and stop it promptly at the door. If children are getting ready for bed or a housemate is watching television, use vibration with a restrained tone. That gives you a clear finish to the run without turning your reminder into everyone else’s interruption.
Common questions
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.
Can I change the alarm sound?
Yes, there's a short list of tones to choose from before you press Start. Pick whichever one you're most likely to actually hear — softer sounds are easier to sleep through than a firm chime or bell.
