Burn morel hunting in BC Interior, remote National Forest areas, or Alaska - places where cell service doesn't exist.
Thick forest coverage can block cell signals. GPS still works because it uses satellite positioning.
Valleys and canyons often have no cell coverage. Perfect chanterelle and porcini habitat, terrible for internet.
Extended backcountry expeditions where you're away from service for days at a time.
Yes. GPS uses satellites, not cell towers. Your phone receives GPS signals anywhere with a view of the sky. Cell service is only needed for internet data, not positioning.
The complete species database uses approximately 150MB. Maps vary by region but typically 50-200MB per area. We recommend downloading over WiFi before your trip.
Everything syncs automatically. Pins, photos, and notes upload to your cloud backup as soon as you're connected. Nothing is lost.
Not directly offline, but you can export your data to share later. We're working on local peer-to-peer sharing for future updates.
Yes. Full offline functionality is available on both platforms. Core features work identically across devices.
Equally accurate. GPS accuracy (typically 3-5 meters) is determined by satellite signals, not internet. Your position is just as precise offline as online.
