Nag, nag, nag...

The Apple Watch has a sleep monitor app which can keep track of your sleep patterns based on, I'm assuming, things like your heart rate and the amount of moving around you do.

Under normal circumstances this is kind of cool, but if you're having a stressful week, your watch will cheerfully add to it by chiming and haptically tapping you on the wrist over breakfast to inform you that "Your sleep score was poor last night".

Thanks, HAL, I was aware of that. I don't need to be chided by my watch before coffee.
