How does offline location sharing work?
goTenna leverages the GPS on your phone, which works all the time even if you don't have service. goTenna then contextualizes that "blue dot" on detailed offline vector maps and allows you to share it with others who have goTenna.
All our maps are free for download, and you can share your location, request others' locations, and also share points of interest. The maps are detailed enough to show specific city blocks and even some trails in certain parks.
