that I can buy/download to my note2 (or any phone really) that warns me when I am more than 5 feet from it. I appreciate that it would have to be linked to a transmitter of some sort, such as a wrist ban, necklace, watch etc. Ideally if I left my phone in a restaurant, bar, or someone else picked it up and walked off with it, it would activate and "scream" out a warning, such as "you forgot me!" Or is this SciFi stuff?
