Web alarm clock for 8:56 a.m.
You are tying down the final crates of vegetables and getting off the boat before the tide changes. Set the alarm for 8:56 am so the last check has a clear stopping point, with 9:00 am close enough to keep everyone moving. Leave once the load is secure rather than letting another small task delay your departure.
The sound should suit the wharf while the vegetables are being loaded. A softer tone works when you are holding the phone nearby and only need a discreet cue; a persistent tone makes more sense above an engine, voices, and crates shifting on deck. Keep the page active and the phone awake, because the alarm may not sound if you leave the browser or the phone sleeps, and that could leave the vegetables aboard past your planned departure.
Before heading ashore in the bright Philippine morning, lower the screen brightness enough to avoid glare but keep the digits easy to read. Shade the display with your hand if sunlight is already reflecting off the water, then place the phone where the screen faces away from direct light. That makes the 8:56 am cue easier to notice during one final look around the boat.
