This application logs GPS data to a CSV file on the memory card as it arrives from the phone's GPS device. Nothing more, nothing less. This is not a "sports tracker."
Data is written to folder "/Android/data/fi.iki.asb.android.gps.logger/files". Load the files to a spread sheet or some GPS visualizer service and tinker away as much as you like.
Once logging is finished, you can use the configurable handlers to process the logged data. These handlers can be used to reduce the effect of GPS errors, filter out irrelevant data and output statistics.
This application is free and does not contain ads.
