- People editing cycling and other GPS activity files
- Worth noticing
- The merge tool describes combining GPS and heart-rate data from one device with motor and battery data from another.
Field notes
The tool list covers both file cleanup and activity editing, including timestamp shifts for a device clock or time-zone error. Its examples point to multi-device ride recordings and FIT files with structural or timing problems; the extracted page links to the app but does not expose its interface.
