It's that time again. Updates now available to my apps: GPS Anti Spoof and GPS Anti Spoof Pro. If you already have one of these installed on your device, update should occur automatically, but you can, of course, manually update by visiting the app store for Apple iOS or Google Android.
Note: This update is strongly recommended for all users. there is a minor cosmetic change to the way the app opens. That's not important. There are also updates to ephemeris data and predicted values of DUT (the small difference between "Earth rotation time" which is the time required for celestial navigation and standard UTC which is the time we see on clocks --close enough to -0.23 seconds for the remainder of this year).
