    Re: Just a heads up (GPS Anti Spoof app)

    Paul Jackson, you wrote:
    "My GPSAspoof app on an Apple iPhone shows the moon dropping in altitude by 1 degree every 13 seconds. It's funny to watch!"

    I'm not seeing anything like that on any versions of this app on my end. Anybody else? Please send any reports of anomalous behavior to me by email: Frank@ReedNavigation.com.

    Paul, I recall that you reported similar behavior (by email) in January 2024. Then, with no changes on your end, it was back to normal within a few hours. Two general suggestions: 1) Reboot your phone. 2) Visit the App Store and see if you have a pending update. That may be the problem. 

    Also, can you tell me which generation of iPhone you have? How old is it? If it's more than about five years old, a day will come when it may no longer be able to get updates. Unfortunately, that's normal in modern smartphones. :/ 

    Thanks,
    Frank Reed
