Apple Watch supported. ■ 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. ■ Notes and Disclaimer ・The developer assumes no responsibility for any damage caused by using this app. ・Take care against water and cold if your device has limited durability. If it powers off from cold, warm it in your pocket and relaunch—log recording will resume. ・Allow location services on first launch, or enable them later in Settings > Privacy > Location Services. ・Free to install with some features unlocked via in-app purchase.
