Slopert ,


I live in the USA, State of New Jersey. I have a need to convert Lat and Long to NJSPCS83, so this looked like the best selection. I paid the $10 and downloaded the app only to have it tell me my Lat and Long was “out of the bounds” for New Jersey! The app says the range for NJ is Lat 32-37 degrees and Long of 103-107 degrees. WRONG! NOT EVEN CLOSE!!

Waste of $10 which I would like back!
