Tracktor: GPX tracks loader

A free loader of GPX tracks in the Yandex Map Editor Notepad with a built-in tracker, an analog of the web version of the Cartographer's Notebook, but without the ability to create points with notes on the map.

It can build a track in the background, as well as when the screen of the iOS device is turned off. Holds the user's geolocation point in the center of the screen.
