The more power user things I do would be to change the complications on my Apple Watch to keep it in context such as AQI and or something like an ETF I want to look at or setup a world time. I frequently use the timer function on my watch and read my email and reply to emails on my watch. Less obvious is the synergy with the ecosystem such as iPhone and Mac unlocking and keeping track of the weather and using Apple Music on my watch instead of my iPhone to keep tracking my battery and flight tracking.

I also use it to keep track of ChatGPT and Claude and I think one of them I can approve tasks with.
