How to use it
- Export your activity as a GPX or TCX file (see below).
- Choose one or more files. They’re read on your device and never uploaded.
- With several files, you get totals and a table. Tap any activity to see its splits and elevation profile.
Where to get your files
| App | How to export |
|---|---|
| Strava | On the Strava website, open an activity, open the ⋯ menu and choose Export GPX. It isn’t available in the app. |
| Garmin Connect | On the Garmin Connect website, open an activity, click the cog icon and choose Export to GPX or Export to TCX. |
| Other apps | Look for Export or Share as GPX. Most running, cycling and hiking apps offer it. |
What the numbers mean
- Moving time leaves out stops, so your pace isn’t dragged down by traffic lights.
- Elevation gain adds up the climbs after smoothing out GPS noise, so it may differ a little from your app.
- Splits show the time for each full kilometre or mile. The fastest one is starred.
Frequently asked questions
Can it open FIT files?
No. FIT is a binary format. Export the activity as GPX or TCX instead.
Why is heart rate missing?
Your file only has heart rate if you wore a heart rate monitor and the export includes it. TCX files from Garmin usually do.
Are my files uploaded?
No. They’re read by your browser and nothing leaves your device.
