I will second the Apple Watch recommendation. I have an Apple Watch, and to be honest I really don’t care for it - the charge only lasts a day, and despite my turning off notifications, it buzzes beeps and squeals all the time. It nags me about standing up, and it is always nagging me about moving, because I leave it on the nightstand when I’m awake. So it sits doing nothing for 16 hours a day and it presumes that I’ve done the same thing. Every time I go through the software and turn off all the notifications, a software update comes out, and sets them all back on
That said - it pairs easily with my phone, it does have crash, recognition, and it is worn on my wrist, and because I don’t care about it, I am more likely to wear it if I’m working on a car.
Siri can be enabled, and it can make emergency calls from your phone if your phone is nearby.
