My daughter lost her Apple Watch on her way home from school today.
Minutes later I was using Find My to locate the Watch and saw that it was on the move with almost no battery left.
A ten minute walk from the house was the last location Find My would show me.
I was afraid of calling the watch and using up the battery. But after several minutes of not finding it at the last position, I took a chance and called it.
Luckily someone answered and told me where to pick it up. 10 minutes later I was back home and the watch returned to my daughter.
I really like Find My.
