What about people who are doing other things?

• I’m getting dressed and would like notification when the coffee is ready
• I’m out doing yard work, but want to be notified when the laundry is done so I can feed the next load

While I could do one thing at a time, or use a clock or at a timer, getting the notification makes it stress free

Think of it as equivalent to the dryer buzzer. It used to notify us when the laundry was done so we can start the next load, but apparently we need a more complicated way to do that
