Is there an app that will automatically recognize when I am near my bluetooth headset (which I keep in the car) and turn bluetooth on, then off again when I am out of range? Same for my home wifi? I typically turn one off and the other on when I leave the house or come home. Any way to automate it? I know there are ones where you can schedule it, but I don't have a predictable schedule, so that won't work for me.
