You don't have to separately update the tracker location. The latest location and the time from the latest location change is always presented in the Snowfox Family application.
Thanks to a smart location and notification algorithm, Snowfox has a long, several days, lasting battery life. The algorithm also takes care that the application is able to always represent a clear view of the last location and a track.
The tracker has a 30 second location update interval and the information is updated to a background service if there's a more than 50 meters' (160 feet) difference compared to a previous location. Normally the location accuracy is around 30 meters (100 feet) and it is good to keep in mind that there's always some uncertainty with the GPS tracking.
