The brief
Kestrel downloads vector topo maps by region and navigates with GPS alone. Hikers record tracks, mark water sources and share routes as a single file. Battery-aware location sampling gives a full day of tracking on a mid-range phone.
Highlights
- Region downloads with vector tiles, 70% smaller than raster
- Battery-aware GPS sampling for all-day tracking
- Wear OS companion for glanceable directions
