Know where I am

Stand at each place once and save the spot. After that the page opens on the right list by itself. The spot is kept on this phone only.

Copy the lists to another phone

The lists live on this phone. This makes a link that holds all of them. Open it on another phone to load them there, or keep it as a backup.
