Started as a car tracker, in the process to become an app consolidating various tracking services. ALL OFFLINE.
Track car consumption and GPS position of refuelling points. Can track GPS position - and statistics - of routes as well now
Added background service for non-car related location tracking. If the background service is enabled (settings page), it collects the position once every hour and stores it along with the cars data.
Can export the collected info in KMZ and Json format.
