What can I do to get her off of it?

Have a game night, or at least two hours a day strictly for family, where their attention is family based. I don’t recommend just taking her phone away or doing anything drastic, as this could just cause more conflict where there doesn’t need to be any. As a personal tip, try Geocaching as a family! Geocaching is a giant treasure hunt that is available to everyone and you’d be surprised at how many are in your neighborhood alone!! https://www.geocaching.com/play
I agree, we have been geocaching for years. Love the gadget caches! No, even a waterpark pass didn't help with her this past summer .
