A few more apps added to the list today. While the GoodReader apps are not Aviation specific apps, they can be very useful for displaying Charts and Maps downloaded in PDF format.
Fli-Quote (iPhone)
GoodReader (large PDF viewer) – read big PDF files with reflow (iPhone)
GoodReader for iPad (iPad)
GoodReader Lite for iPhone (iPhone)
Fli-Quote is a good aviation app. Takes a second to figure out the profiles/favorites feature, but a very useful app nevertheless. Recommend the download.
Latest version can be used to read the Instrument Flying Handbook. Very nice!
