Here's an idea to make Live Track more useful, if it hasn't been suggested already.
Live track recipient alerts
It might work as follows:
1. Recipient receives standard message/email "You are invited to watch a live activity etc."
2. Recipient opens link and displays web page in browser
3. On the webpage there is the option to select alerts to the recipient's phone/email e.g.
- when the originator gets within say 250m of a selected location such as the recipients location, or another location of the recipient's choosing
- when the originator returns to within say 250m of their staring point
- when the originator stops for more than 5 minutes
I've submitted the idea to Garmin.
I didn't bother describing any use cases, but it doesn't take much imagination.
