Works for me

I have compared this with my little Garmin eTrex, downloading the files to Google Earth and Arcview (the Arcview takes a little manipulation in both cases). When there is no cell-phone signal to the iPad, this app still matches the aerial photos better than the Garmin. When there is a cell phone signal, it matches much better. I have not checked elevations. This app is easy to use and it is easy to export the data. Happy camper.
