Quick explanation
The tool displays the current time, lets you copy that time as a starting point, then lets you set the alarm time with plus and minus buttons. The alert mode can be steady or blinking, and the alarm triggers when the selected time matches the local time of the device.

Additional information
How to use the visual alarm
Set the alarm time with the four digits displayed in the tool. The first two digits are the hours and the last two digits are the minutes.
Each digit has its own plus and minus buttons. These buttons only change the associated digit and do not automatically carry the value to another field.
What does the Copy current time button do?
The Copy current time button fills the four digits with the local time reported by the device. This is useful when you want to start from the current time and adjust only a few digits.
The alarm works at minute level. Clock seconds are not used to schedule the trigger.
Which alert modes are available?
The steady mode displays a stable visual alert when the selected time is reached. The blinking mode alternates the alert appearance to make it more visible.
The mode can still be changed while the alarm is scheduled and before it triggers. The active mode at trigger time determines the alert appearance.
How does the alarm trigger?
Once scheduled, the alarm regularly compares the current time with the selected time. It triggers as soon as the hour and minute match.
The alarm is not linked to a specific date. If you schedule the current time, the alert may trigger immediately.
How do you stop the alarm?
When the alarm is triggered, it remains active until you use the stop button. In blinking mode, the visual effect continues until the alarm is manually stopped.
Does the alarm produce sound?
No. This alarm is entirely visual. It does not play audio, vibrate the device or create a system notification.
It is suitable when a sound alert would be disruptive, but the screen must remain visible at trigger time.
Does the alarm work if the page is closed?
No. The page must remain open so the tool can keep comparing the current time with the scheduled alarm time.
Refreshing the page, closing the tab or letting the device enter a strict sleep mode may interrupt the alarm.
Which time does the alarm use?
The tool uses the local time provided by your device and browser. It does not request a time zone and does not perform geographical conversion.
Make sure your device time is correct when using this alarm for a precise reminder.
When is this visual alarm useful?
Use it during a work session, meeting, study period, quiet activity or any situation where you want a visual reminder instead of an audible signal.
It can also be useful on a secondary screen, as long as the tab remains visible.
Precaution with blinking mode
Blinking can be uncomfortable for some people. Choose steady mode if you are sensitive to flashing effects or when using the screen in a dark environment.
This alarm should not be used as the only warning system for an important, medical or safety-related situation.
