hDrop now writes your sweat and electrolyte losses into the matching Strava activity, so the hydration result from a session sits next to the pace, power and heart rate that produced it.
- After hDrop analyses a workout, it adds a post-workout summary to the description of the matching Strava activity.
- The summary shows total sweat loss, sodium loss and potassium loss, where the hDrop app has those results.
- Any notes you have already written in the Strava activity description stay in place.
- The results are not a live feed; they sync only once the activity is on Strava and the phone has an internet connection.
- You connect the two accounts in the hDrop app under Account > Connected Apps > Strava, as described on hDrop’s Strava integration page.
What it means for athletes
hDrop gives live sweat and electrolyte loss during your workout. Now the same sweat and sodium numbers stay in your Strava training log instead of sitting in a separate app. When you plan fluids and electrolytes for a long ride or a hot race, you can scroll back through Strava and see what similar sessions cost you, or you can literally quantify to your friends how much you sweated in your pain cave.
The figures are only as good as the sensor’s calibration. In the hDrop review, the sensor proved accurate once calibrated, but the hDrop calibration tests showed fluid loss running high before that. Garmin owners who want a second estimate can compare it with Garmin Sweat Loss, but that’s an estimate rather than a measurement.

Does hDrop show hydration data live on Strava?
No. hDrop adds a summary of sweat, sodium and potassium loss to the Strava activity description after the workout has been analysed in the hDrop app.
Will hDrop overwrite my Strava activity notes?
No. hDrop says your existing activity notes stay intact and its summary is added alongside them.
Strava support first arrived in the hDrop app update that also fixed the Wahoo data field, and the hDrop Connect IQ test covers the Garmin data field outdoors.
