What's New in GEO Calc 1.0.2
Stability and reliability
• Stronger handling of unstable networks when loading map tiles
• Safer GPS location updates so Live GPS and Navigate keep running smoothly
• More reliable share and export from the map and waypoints
• Settings sheets (language, units, coordinate order) no longer crash when changing options
• Map camera and saved coordinates are sanitized so invalid values cannot break the app
Maps
• Map measure and pick-from-map recover gracefully from invalid camera states
• Offline, DNS, and TLS tile failures are handled quietly instead of interrupting your work
This update focuses on crash fixes and field reliability so GEO Calc stays dependable offline and online.
