Hi, I tried the app today while windsurfing.
I have a Pixel Watch 4 and granted all permissions, including location access set to “all the time”.
According to the tracking data, I did a lot of jibes, but I didn’t do a single one—only slow tacks.
My heart rate was also recorded strangely. That worked better with the Strava app, as did the calorie calculation.
I imported the GPX 1.1 file into Strava.
Is there anything else I can configure on my end to fix the jibe detection?
If you need any more information, please let me know.
Even if the data isn’t that accurate, I’ll probably subscribe, but I’ll keep testing for now.
Jibe detection depends on the wind direction, which the app fetches automatically from a weather service — but that data isn’t always accurate. You can correct the wind direction manually in the weather editor after the session. Once you’ve adjusted it, see if the maneuver detection looks better. If it’s still off, it would help a lot if you could share the original session file — please send it to support@sunbits.de.
Heart rate is a known issue I’m already working on. It seems to be related to how snugly the watch is worn during the session — worth trying a tighter fit next time.
I had a look at the session. The issue is that during slow maneuvers like yours, the GPS track of a tack looks geometrically very similar to a jibe — because you’re heading up slowly and the turning point goes downwind rather than upwind. That makes it very difficult to distinguish the two automatically.
This is a known limitation for low-speed windsurf sessions, and I don’t have a simple fix for it right now.
I wore the watch very tight today. Even tighter than during the last session with Strava. And back then, Strava tracked my heart rate correctly throughout.
I actually took the tack really sharply. That always completely slowed me down. During that time, I might have moved 0.5–1 meters downwind when I came to a stop, and then carried on.
In my last session on Strava, I can actually see a few gybes on the map as well.
