An important feature of EasyTracker is its ability to choose among various maps (Google Maps, Open Street Map and Microsoft Bing Maps), also the possibility to use offline maps. The latter is very important when the user is currently in an area that has no network or a bad connection. Fig. 2 illustrates two screenshots of the application. Departing from the features that are more or less available in many other similar applications, to protect users’ privacy the application allows registering user-defined areas inside where recording is not permitted. Such an area is defined by a point (either set manually by providing exact coordinates or by touching on the map) along with a desired radius around this point and a characteristic name (e.g. home, work, mam’s house). The user can specify up to five privacy locations using a radius which is limited from 15 meter till 300 kilometers. Fig. 3 depicts screenshots of this privacy filter.
