I have it, you download their app and connect phone to a tile that you then attach to purse or keys etc. Very clever. But, of course, once you use it the app stays running even if you close it, then you get the fun of the usage and standby being the same. Is there a way to use this device NOT using their app but using keychain? Why would I need "refresh background" on for this, cant I keep that off and still use it?
