This might seem to obvious but does anyone make an app that notifies your watch if you've gone out of Blue Tooth/wi-fi range from your iPhone? Everyone has either lost a phone or walked away with it sitting somewhere only to be lucky enough to run back and find it. I myself have found many lost iPhones over the years. At least for me, my watch is within Blue Tooth/wi-fi range 99% of the time. If I was to walk away from my phone (such as a restaurant, etc) I'd love to be able to get a vibration alert on my watch.
