Geographica | offline map

A GPS navigation app for hiking and mountaineering that works offline, even in airplane mode or out of cell range. With Geographica on your iPhone, you can help prevent getting lost or stranded.

■ FAQ
Q. My current location isn't displayed.
A. Location can't be determined if GPS is off. Turn on "Location Services" in Settings. Accuracy may suffer indoors, underground, in urban canyons, or in valleys. Try somewhere with a wide view of the sky.

Q. Map cache disappears automatically.
A. Display cache is deleted after a certain time or capacity threshold. Cleaner apps may also delete it—please exclude Geographica from them. For maps you absolutely need to keep, use the bulk cache function. We recommend saving both detailed and wide-area maps.
