Is there an app that records the coordinates of the smart phone when it loses connectivity with a wearable ( in my case a Fenix 3).  This location could be used to guide the owner back to the phone, not unlike the app that allows a user to find a parked car.  I have lost my phone twice while cycling.  The default 'Find My Phone" app was useless because I was out of Bluetooth range when I realized my phone was missing.  Is there such an app.
