Apple Watch 3/Watchos 5 - Swimming not counting laps or calories correctly.

I’ve contact Apple on this a few times but I’m really pursuing it this time as it’s so frustrating! Their answer today was that the engineers say this is normal (my watch has stopped counting lengths and distance while swimming but when I end the workout the data appears) I’ve said that’s not a satisfactory explanation as when I bought the watch 12 months ago it tracked just fine whilst swimming and was really accurate! Not taking no for an answer this time!

Same thing has started happening to me.

series 3 been working fine for a year and now going wrong.

Doesn’t record lengths or distance in pool swim and during the swim keeps going back to the home screen. Also, calorie count is way out.

All 3 rings keep dropping down to zero then going back up.

The running man man icon is animating in the corner and then stopping for a second, not sure it was doing that before.

Tried everything mentioned here.

Really cheesed off. I use my watch to track my swimming everyday and it’s been faultless for a year.

Same problem on new Watch 4. Worked the first swim. On the second swim it did not track my laps but did show the exercise in the activity loop. I'm new to the watch, so unsure of all the correct terminology. I did the power off app trick and powered off the watch and restarted. Will see what happens on my next swim. So frustrating. I kept stopping and trying to fix t no avail. Not sure what you mean by unpairing. Unpairing with my phone?

Force quitting app didn’t work for me. Also reset the watch as a new watch, not back up

I have recalibrated. It doesn’t help. I agree. It has to be a software issue, because everything worked perfect until updating to iOS 5

Same problem, swim my heart out for 45 min and it gave me 37 cal burned. Never had this issue prior to ois 5 and 5.01 doesn't fix it. I have tried all the resets mentioned with no change. Such a bummer. I use this daily.

I am having the exact same problem. I swam 6 laps, watch counted only 2 lap and 1 calorie. This is a bummer.

Another problem is that when you put watch in water fitness mode you still have to manually put it into waterproof. It does not do that automatically like when you put it on swim mode.

I’m having an issue as well with Apple Watch 4 . In my case, the software is measuring laps properly but halving distance. Each length of our pool is 12 yards but Apple Watch measures a lap as 11 yards not 24.

Don't know how helpful this is, but I do not have this issue. I do the same swim workout about 4 times per week lasting about an hour. I had a series 2 watch for about two years and the upgrade from WatchOs 4 both to WatchOs 5 and 5.0.1 did not have any effect on the number of laps or calorie burn measured - all within the normal variation. I subsequently upgraded to a series 4 watch also running WatchOs 5.0.1 and it gives very similar figures. So your problem not universal. I have not yet upgraded to the latest WatchOs 5.1, so I can't speak to that if that is the version you upgraded to.

Andymnorris: what version of WatchOS got your watch working again? I guess I'd like to see more verifications that the latest version is correctly counting swim laps before I upgrade the OS again. Apple was kind enough to replace my Series 3 watch with Watch OS 4 on it and I don't want to go through the trouble of upgrading to 5 and it not working again.

This only happened to me once ... it has worked fine since, with no further upgrades to the software. I’m not sure why the laps didn’t display during my swim that one time (but accurately showed the total laps in the summary screen), but it hasn’t happened again since that one time.

I am using OS 12.0.1, and now my phone wants me to update to 12.1.1. I jog, bike, and swim, and I simply want a watch that can accurately track them all. I am beyond midlife crisis age, so getting older, but... these constant updates gets old. Oh well... when I swam growing up, no swam with a watch on, and we had to remember our laps.

i find lap tracking to be now correct again also.

but it seems that the wall push off is detected late so that set times come out short, not that i would mind should it be real! but tested agains the pool watch, ist the apple watch (series4) which is short.

anyone else seen the same and/or has a fix? changing wrist fro non dominant to dominant sees to have no effect.

I’m having a similar issue - after the update my Apple Watch 3 is having issues with swimming activity. When I start the workout the time starts - I notice today though that while the clock was counting it was continuously on the same number 3:00 and then counting through the minute but staying on 3. After completing the workout it shows that I have worked out but both the time and yards are incorrect on the watch. When I went to activity on the phone it does not show a workout at all. anyone know a fix for this? Having major issues with swimming workouts after the update
