Show distance away from current location and mark as completed

[EHong]

My app starts with a card view of my customer list so the users can figure out which locations to visit next. Is there a way to display the “distance away” from the current location for each customer’s listing? That way the user can pick the next closest location to visit for maximum route planning efficiency. My Google Sheets data has the column header Current Location with data Lat Long HERE().

Also, the second question I have is, is there a way to show a check mark or highlight on a customer listing on the start page if that customer has been visited by my user already? This way they don’t visit the same location twice by accident?

Thank you so much.
