Your .fit, .gpx, .tcx, .kml, .kmz, GoPro or Insta360 video goes here (multi-chapter OK), or
It takes a few seconds. Nothing leaves your device.
Drop the file your watch, phone or GoPro saved while you were out skiing or boarding, and Flyby turns it into a replay you can watch: every run and lift ride named on a 3D map, your speed, the day's weather, and real sun and shade. It's your day, so you can put it right: rename runs, merge a descent the GPS split in two, and turn a stretch the detector was too cautious about into the run it really was. Explorer shows how much of the mountain you actually covered. Then share it: a one-button highlight film of your best runs, and a Day-print of your route lit by the sun. Works with Garmin FIT files, GPX tracks and GoPro video, right in your browser, with nothing uploaded to us.

🔒 100% private. Your GPS track is read and analysed right here in your browser and is never uploaded. We only ask our server for public resort data: the piste map to name your runs, that day's weather, and the mountain's terrain shape for real sun and shade.
