Web alarm clock for 12:24 p.m.
You are midway through a farm task when you realise the rain gauge still needs checking, so set the alarm for 12:24 pm before returning to what is in your hands. It gives you a clear reason to break away, read the level, and record it while the measurement is still useful. With 1:00 pm approaching, you can finish this small check before the afternoon work begins.
Your rain-gauge check depends on the browser remaining open and the phone staying awake enough to sound the alert. If you close the page or the phone goes to sleep, the alarm may not ring, and the gauge reading could be missed. Keep this page open, leave the sound audible, and place the phone where you can hear it over farm equipment or rainfall.
A midday rain-gauge round can fall close to lunch, especially during a wet Philippine afternoon. If you need something beforehand, have water and a light snack that will not delay you when 12:24 pm arrives. Save a full meal and hot drinks for after you have read the gauge, written down the result, and returned under cover.
