What it does
Trek Log records your location as you walk, hike, drive, or travel. It builds a route in the background and keeps everything on your device. When you're done, you can export it as a KML file — readable by any GIS tool that understands standard formats — as an animated GIF if you want something shareable, or as an MP4 if you'd rather watch the route play back as video.
The route belongs to you. There's no account to sign into, no server storing your data, and no subscription to forget you started. Routes are saved to your iCloud Drive — in your own storage, your own account. The app has no visibility into what you've recorded unless you're looking at it directly on your device.
It doesn't do turn-by-turn navigation. It doesn't share your location in real time. These are not missing features. They're absent because they require a server, and the point is that there isn't one.
