The question is in subj. Recently switched to Apple infrastructure and witch my attention span got a problem. When I left my watch behind I would like my phone to remind me of that. Can I do it?
Maybe you could make an applet in IFTTT for this. Just a simple notification when you leave a location (home) to check for your smartwatch. You could probably build an applet if you leave a location but your smartwatch doesn’t, though it looks like they have a pro/paid version you’d have to subscribe to.
I wish there was a simpler and more native way to do this. Because I found a way to get a notification on my watch if I forgot my phone, but not the other way around, and now I’m trying to figure that out.
Actually, it looks like Apple has this option built in.
