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

Same here. I swam for 30mins as usual and my watch said 0 laps!! Is there any fixes yet?

i think this happens every time there is an ios update. That was my experience. Apple should look into this.

Same issue here: I have aaple watch 4 on watch OS 5, but the swim workout overcounts the distance I swam. I usually swim about 1 km, but watch says I’m swimming 4-5km.

Is Apple listening to this or do they care? Why cant they correct this on the next IOS update?

Talked to Apple Support this morning and they suggested recalibrating the watch. (Instructions here: Calibrating your Apple Watch for improved Workout and Activity accuracy - Apple Support). I'm going to try it, but won't be swimming again until Friday. If this works for others in the meantime, let us know.

Hi all I am having the same prob I swim 52 lengths since update it’s registered 2,11,2,7 and 3 lengths,

The calories are miles out to.

I’ve unpaired the watch, cleared and restored from a back up I’ve also unpaired, cleared and set up as a new watch still faulty.

I phoned apple who knew nothing of this fault, and they booked me in for a visit to a store to check the watch for Saturday, I really think I am wasting my time going as it seems obvious that it a software fault.

I’ve just checked and there is a update out, it doesn’t mention about swimming but it does say something about activity tracking, I have updated but I won’t be able to test it till Monday.

If in the meantime anyone does do the update and tries it before Saturday could you please post an outcome as it will save me a long trip to a store.

Otherwise I will pop an update on Monday.

Thanks Andy.

Hi. I was having the exact same problem right after I updated the software to WatchOS 5.0.1. After 4 weeks dealing with Senior Advisors and people from the Engineering team, they offered me a replacement without the update. I don't know if they will do that for everyone, since I have AppleCare+. I will try it today in the swimming pool, but I guess it will work just fine. Does anyone know if Series 4 has the same problem with WatchOS 5? I don't think I will update it in a while...

Same issue here but I was in the pool trying to squeeze in 2500m, I got to 2550 and jumped out and finished the workout. I got home and workout app is only showing a 1000m swim but gave me the calories, almost closed the move ring, closed exercise ring and shows the hr duration of my swim just the distance is way off. Super frustrating. Anyone find a fix to this iOS 5 update glitchiness? Thanks in advance! Just noticed cals are off too!!

I've had a similar problem since at least series 2 and I now have had a series 3 and currently a series 4. The watch keeps the swim time correctly, but the yardage shows "0 yards". When I finish my swim and discharge the water and stop the swim, the correct statistics show up (from what I can tell). It sounds like Apple's Software V&V is really awful. I've complained about this several times with Apple, and I'm on the phone with them for as much as an hour, but it does not help at all. This is an intermittent problem, but it seems to be happening all of the time now. I guess I can go back to a Casio Pathfinder with a titanium band with steel pins that rust, if I have to count my own laps. These apple watches are not free and Apple is not addressing this because it's been going on for a few years now. Apple refuses to refund my money and they are not transparent with what is really going on. Too bad, otherwise, it's a nice watch. I also use it for bike rides and it seems to be working well in that application.

Same problem here. I’m on 5.2.1. Lap counting worked fine yesterday, but today it decides not to work. This is the 3rd or 4th time it’s failed in the past year or so. What gives??? The engineers / product managers on this feature get paid $300-400k per year and get *plenty* of testing resources. Why can’t they fix this one for good?

Hi there, I have the apple watch series 4 cellular and I have been using it while training for my first triathlon and today for the first time it stopped counting the laps on the display but is still registering the laps when I finish the swim and save the workout. Is anybody able to help? Watching the laps as I go along really keeps me motivated.

Hi! Checking back in on this. I was able to fix this by completely by "force" shutting down and restarting my watch after the last update. No need to reset or re-pair. It just worked after that.
