Delete all stored tracks and waypoints in your browser's local storage
How to use this app
Enable the GPS on your device and allow location access when prompted. The compass will show your phone's
heading. A track will record your location. Tap the screen to drop a waypoint with a name and description.
The track and waypoints are stored in your browser's local storage, so you can access them later. You can
download the data as a GeoJSON file.
