With the trakkio iOS application you can view the live location of your trakkio trackers, and you can manage them too. You can install new geofences, add notifications, get push messages and much more.
When following a tracker you can see them moving live on your map, and you can display your own position on the map as well if you enable location services to be used. You can not track your smartphone with this application. You do need an account for the trakkio platform and have trakkio GPS trackers.
