- Trackers can be handed to someone without a phone or clipped to a dog’s collar; the site says their radio can display messages and alerts.
Field notes
The setup is organized around a trip: download map areas, create or join a group, then pair radios for stretches without cellular service. Its stated offline coverage is U.S.-only, drawing on USGS terrain and place data, BLM and Forest Service lands and roads, and USGS aerial imagery; radio setup is specified for the U.S. 915 MHz band. The site labels its Google Play release as testing and links to setup, troubleshooting, and a printable tracker card.
