How to use the online alarm clock
Waking at 6:10 am gives you a quiet starting point before setting off for the construction site, while your boots, keys and travel mug are still where you left them. With 7:00 am ahead, there is time to get dressed, check the route and leave before rush-hour traffic begins building on local roads.
For this alarm, the browser needs to remain active until the chosen time. If it is closed or the phone falls asleep first, the sound may never play, leaving your construction-site arrival without its planned warning. Keeping the handset connected to power and preventing automatic sleep reduces that risk. The volume should already be audible, especially if the phone was silenced overnight, and a separate backup alarm is sensible when the site has a fixed arrival time.
Before an early journey, a bright screen can feel harsh in a dim bedroom and make keys or directions harder to read comfortably. Lower brightness before checking the route, use the warmer display setting if available, and switch on a bedside lamp rather than staring at a glowing screen in darkness. Once everything is ready, placing the phone face down keeps the light from becoming an extra distraction before departure.
Common questions
What happens if my laptop goes to sleep before 6:10 am?
The tab sleeps along with it and the alarm will not sound on time, if at all. If you are relying on it, change the power settings so the machine stays awake, or keep a phone alarm running as well.
Do I need an account or an app?
Neither. Choose a time and a sound, press Start, and it runs in this browser tab. Nothing is downloaded, nothing is registered, and closing the page leaves nothing behind on the device.
Can I change the sound?
Yes, there is a short list of tones to pick from before you press Start. Softer sounds are easy to sleep through, so a firmer bell tends to be the safer choice for anything early in the morning.
Will it still be right when the clocks change?
Yes. It reads your device's local clock, so the move between GMT and BST at the end of March and October is picked up automatically, as long as the computer's date, time and time zone are set correctly.
