Pretty Worthless
I bought this app about a year ago as I typically rent a lake house in Western NY and am curious about the planes I see flying overhead, particularly at night. I have found that I point my phone right at a plane and get no data or its obviously inaccurate, i.e. the app says the plane is at 33,000 feet when I can clearly tell its not. I would recommend you save your money simply because its data is unreliable.
