One workout.
All your data.

Echo makes your Strava activities whole — combining equipment data with heart rate, or reuniting split recordings into one.

Your equipment and your watch, one activity.

Echo finds activities that belong together — equipment and watch from the same workout — and shows them as a single card.

Split recordings, stitched back together.

When your activity splits across devices or a recording restarts, Echo finds the pieces and puts them back together.

What Echo does

Uploads a proper FIT file

The result is a standard FIT file that credits each source. Strava computes Relative Effort, Training Load, and Intensity from the real data.

Your data stays on your device

All processing happens on your iPhone. Activity data goes from Strava and Apple Health, gets processed locally, and uploads directly back to Strava. Nothing is stored or sent to Echo. Anonymous usage statistics help improve the app — no names, no health data, no tracking. Read the privacy policy for details.
