I am going to get a new cell phone in a week or so, and may put "sharktivity" on it.-Tom
I don’t have an app. I’ve used this rule: Dry land = no sharks, in the water = could be sharks. Also, if you are in the water and hear creepy music, get out of the water. Something really bad is about to happen. That also works for spooky houses too. It’s kept me safe for decades.
The only exception of sharks on dry land is in the fish department of a grocery store.
Just loaded it, the 3 most typical places, Chatham, National Seashore/ Marconi Beach, up towards Provincetown. All Ocean side.
