Yeah, I haven't figured out all the details on Apple's App Store and how the pieces of the app descriptive text interact.
The basic functions of the PRO and standard versions of the app are the same. The differences: the low-price standard version provide data for the Sun and a couple of key stars (which may change with the seasons). Also the standard version is not intended for long-term off-network use. The standard version will work for a few days, up to a week, without network access. The PRO version of the app is intended for serious navigators. It includes data for the Sun, Moon, Venus, Mars, Jupiter, Saturn, Polaris, plus the other 57 "navigational" stars. The PRO version will also function off-network for months at a time and is intended for use at sea.
PRO (Sun, Moon, all planets, all stars, long-term off-network):
- GPS Anti Spoof Pro app for iPhone/iPad, $$. Now available.
- GPS Anti Spoof Pro app for Android, $$.
STANDARD (Sun, a couple of bright stars, short-term off-network):
- GPS Anti Spoof app for iPhone/iPad, $. Now available.
- GPS Anti Spoof app for Android, free.
