Yes. Under Mountain, choose GPS file and drop in a GPX, TCX, KML or GeoJSON file from your watch or app (Strava, Garmin Connect, AllTrails, Gaia). The file is read in your browser and never uploaded. The builder finds the summit for you: the highest named peak your hike came within about 400 m of. The date of the hike fills in the date line.
