Import your sessions

Send the files of your laptimer as they are: LapViz recognizes the format from the content of the file, not from its name.

Device times
The laps recorded by the laptimer are kept. On a circuit known by LapViz, the laps and sectors are also calculated from the GPS, to compare with the other drivers.
Recalculated times
The file has no laps: LapViz calculates them from the GPS track, on a circuit known by LapViz only.
