Quick answers about KnotNow Sessions and how to get the most from your data.
What file formats do you support?
GPX and TCX. Most GPS devices and apps can export in one of these formats. Up to 10 MB per file, 15 files per upload.
Where can I get GPX or TCX files?
From Garmin Connect, Apple Watch (via HealthFit, RunGap, or similar), Strava, or any device that records GPS and exports activity files. See our upload guide for step-by-step instructions.
Do I need a special app or watch to record?
No. Use whatever you already have – Garmin, Apple Watch, Strava, or any GPS logger. We don’t have a dedicated recording app. You export from your device or service and upload to KnotNow.
