Web alarm clock for 1:24 p.m.
You are partway through preparing the papers and safety details for clearance to take a small boat out, so a 1:24 pm alarm gives you a firm moment to break away and check for the reply. If nothing has arrived, you still have 36 minutes before 2:00 pm to confirm the required information without losing track of the work already in front of you.
While you wait for the small-boat clearance, set the alarm and check where your browser audio is playing. A phone or laptop may quietly route the sound to connected earphones left in a bag or another room, so test the volume and output before returning to your task. Keep this page running and the device awake: otherwise the alarm may not sound, and you could miss the point when you meant to review the clearance.
Because 1:24 pm falls around midday in the Philippines, your reminder may sound while other people at home are eating, resting, or working nearby. Choose a clear but moderate volume, and keep the phone close enough for you to hear it without making everyone else respond. If you must step into another room, tell them what the alarm is for so it is not mistaken for their own reminder.
