Online: browser tools like GPSVisualizer or Google My Maps work for quick previews but need internet for map tiles. Offline: a mobile app with cached maps is essential for backcountry hikes.
Our recommendation
Use GPX Viewer on iPhone or Android for daily GPX viewing. Upgrade to Pro for offline maps when cell service is unreliable.
