About

Sports watches and route planners speak different file formats: GPX, FIT, TCX, KML... and your Mac, iPhone and Watch open none of them well. This app fixes that, then goes one step further and puts routes ON your watch. * Open any GPX, FIT, TCX or KML * Map view, elevation, heart rate and pace charts, per-km splits, the device's own laps * Press Space on any route and see it drawn, with headline stats * Route thumbnails for FIT files, right on your Mac * Works with Garmin exports, Strava bulk archives, AllTrails and Komoot downloads, coach emails * One click makes it the default app Route Viewer Pro: * Send to Watch - USB mounted devices writes a ready-to-ride course onto any device that mounts as a USB drive (Edge bike computers, many older watches) - Current Garmin watches: AirDrop the course to your iPhone or hand it straight to Garmin Connect in your browser; either way it syncs to the watch wirelessly - Apple Watch: AirDrop to your iPhone; share to your watch from the app * Route converter: any GPX, KML, TCX or FIT becomes a watch-ready FIT course, with turn-point cues and Virtual Partner timing * GPX export: clean files for sharing, or AirDrop to iPhone watch apps One purchase across all devices * iPhone and iPad: open a route from anywhere via the share sheet, see it on the map, and share a course straight to Garmin Connect or AirDrop it to your Mac * Apple Watch: send a route to your wrist and follow it. The route draws as a breadcrumb with your position on it, the distance you have left, and an arrow back to the line if you wander off it Private by design; no cloud storage or interim steps.
