While recording a track, the app continuously retrieves data from your device's GPS module, updating the current position on the map in real-time, typically capturing values every second, producing highly detailed tracks of your activities. The problem is that sometimes (specially when accuracy is low) the values vary a lot, making the current position to "jump" between distant points in the map.
Latest models of mobile phones are highly accurate and can locate your device with a precision of up to 3 meters, but environmental factors and device settings can impact its accuracy significantly.
With the GPS filtering feature Guru Maps users can rely on more accurate and reliable recorded GPS tracks for activities like hiking, cycling, or off-road adventures where precision matters.
