Anyone know of a activity tracker collar that will show distances traveled? I don't really care about any of the other features the collars have. I'm not worried about my dog escaping or getting lost. I like to take my dog to the beach and she runs up and down the beach chasing birds and think it would be cool to see how many miles she covered. Ideally really looking for something like a running app on your phone that gives an outline of where you went and how far you went and how long you have been running for. I'm not sure if the popular gps collars like the Fi, or Whistle do what i'm looking for. Any advice would be appreciated.
