A Hiking GPS Tracker
for those who make their own way.
And want to keep their data private. No social feeds. No selling your location. Just professional-grade tools for the independent explorer.
Requires iOS 18 or later.
"Navigation is a skill."
You pack the ten essentials and know how to read a topo map. You don't need an app to tell you where to walk. Coati Hiking Diary respects your skills by focusing on what matters: battery-efficient tracking, field reliability, and private data logging.
For the Explorer: Trail, Off-Trail, or Cross-Country.
