Set the timer to 147 minutes

Online timer for 147 minutes

You’re keeping a child or student settled while a tradie crew works within a loosely described half-day window, so the countdown becomes the boundary for both of you. Two hours and twenty-seven minutes is long enough for homework, quiet play and a proper break, yet specific enough to stop the afternoon feeling endless. You can explain that the alarm marks the agreed finishing point, even if the crew is still packing up.

With drilling, conversation and movement around the house, the alert needs to reach the person supervising the session. Sound can slip into connected headphones without the wearer noticing, leaving everyone else unaware that time has finished. Keeping one ear free, disconnecting unused headphones, or placing the device where its screen is visible helps the countdown remain useful without competing with the crew’s noise.

While you’re supervising someone else, a phone is easier to carry between the kitchen, study area and front door when the crew needs access. A laptop suits a child working at a desk because the remaining time stays visible, but its alert may be missed from another room. For a stretch that covers several activities, use the phone if you expect interruptions; use the laptop when the session will stay in one place.
