Hey, I have my watch set up where it vibrates when the phone goes out of reach. There are plenty of apps like that. I was wondering if there existed something where the other way around would work? The reason I would like something like this is because it could be a good way not to forget items when going out. For example, I was at a party today and didn't want to forget to take my coat when I leave. If I had an app like this, I could simply put the watch in my coat and if I leave without my coat, my phone would ring/vibrate.

Thanks
