Field notes
The homepage exposes four workflows: joining recordings, combining GPS from one device with heart-rate data from another, drawing a missing route, and comparing up to four activities. Supported uploads are GPX, TCX, and FIT, with per-file limits of 20 MB and 200,000 points. The page says users can export results for upload to Strava; the extracted evidence does not show an example output or confirm processing behavior.
