Thanks for the input  - my NAT friends!

Several folk in my home town suggested 'find my friends' - but then added the qualification - "It only works on Apple I phones!"

We are now set up with Life360. My nephew's daughter and her husband use Life360 from Apple to Android.

Life360 is now set up on an Android that will be with my sister as she drives the two hour trip.

Where she is going to can track her position whenever they like!

Beaudy!
