Re: longitude latitude app for windows phone

GPS Calculator looks good. As long as you don't need a map, these apps should work well even without internet... since GPS does not need a data connection.
I understand that your conserving data. However, though a lot of forum members will be glad to help, most of us are not call center agents. We may assist you, though we may be not as diplomatic... and most of us don't make a living out of our generosity.
Here is some advice: while performing a search in the Store, you would notice that there is an app rating with stars together with the number of ratings received - these should give the user an idea on how well-received the app you're looking at is. If the rating catches interest, the user may look at the app and head over to the reviews and read what other users have said about that app. If the comments and reviews are good, you could check the screenshots and images the developer/s has/ve placed in the app main page and see for yourself if the app appeals to you without having to download the app just yet. As long as you don't download the app yet, the entire process will not consume so much data. If you're satisfied with what you saw, then begin downloading the app. Don't forget to leave a review afterwards.
Hope you find what you're looking for.
