iOS 8 Health Apple Watch incosistent readings

In addition to fixing performance issues and a number of problems related to the accuracy of fitness tracking, the first software update for the Apple Watch seem to have introduced an unintended bug.

The affected owners have flocked to Apple Support Communities and MacRumors’ forums to report that the device is now capturing their heart rate readings less frequently than before after updating to Watch OS 1.0.1.

Apple says the device’s heart rate sensor should capture heart rates every ten minutes throughout the day — even more frequently during workouts — but there are now noticeably larger gaps of time between data, some as long as an hour or more.

I was able to confirm this myself.

As evidenced by the screenshot above, I fired up the iOS 8 Health app on my iPhone, tapped the heart rate panel on the dashboard and then tapped Show All Data to browse the recorded heart rate readings. Or, you can go to the Health app’s Data tab and then navigate to Vitals > Heart Rate > Show All Data.

As you can see for yourself, my Apple Watch has been taking heart rate readings far less frequently than before, in most cases every hour or so, and in some instances even longer.

Checking our the heart rate Glance on my Apple Watch has confirmed my suspicion that the device’s heart rate monitor captures data less consistently than before.

Worse, I’ve noticed that the device wouldn’t increase the frequency of hear rate readouts when I’m far more active during cycling, running and other workouts.

It’s important to note that this shouldn’t pose a major problem for most Apple Watch owners. However, folks who rely on the Apple Watch as their all-round fitness tracker should be concerned about this behavior as it leads to far more sporadic heart rate readings than expected.

We’ve reached out to Apple and will report if we hear back from them.

To check out if you have the latest version of the Apple Watch operating system, fire up the Apple Watch companion app on your iPhone and navigate to General > About. Under the Version section, you should see “1.0.1” if you’re running Watch OS 1.0.1.

    To me 1.0.1 is running worse than 1.0. My watch lags more and it also becomes unresponsive.

      It definitely does take it less frequently. I don’t have any lag issues with the update yet. The first update for any IOS device usually has a lot of bugs.

        Rowan, it’s getting to a point that a near trillion dollar company should not have many if at all bugs on any update. They want to boast sales records, share prices, percentage of users on the latest o/s be my guest. How about Apple boasting that they’ve provided an update that has no bugs and is only a continuing improvement. Then they can sprout the other stuff. Then they can justify being worth a trillion dollars and then they shouldn’t have to rely on the good folk such as yourself making excuses for them. This is not directed at you, however through observation and curious questioning, some people excuse these ‘bugs’ out of embarrassment and feel somewhat conned. It’s unacceptable and as long as it’s passively tolerated, their impetus to offer a bug free update just won’t.

        there will always be bugs in software.

      • Rowan09

        No company is perfect and people will always miss things especially since they are releasing software on a schedule. There’s a reason people always update their code, etc because of new ideas, bugs, etc. I’m not making excuses for them it’s just the nature of the game, if you actually did some coding it would make more sense to why people forget something or make mistakes. These big companies put a lot of pressure on people to release products, updates, etc and that’s one of the issues.

        Given the volume of bugs that have been introduced and/or serioys effects caused, take ios8.1 etc with the wifi issues, followed by another update etc. It is unacceptable to have these sorts of bugs or errors whatever you want to call them. If the motoring industry can bring down recalls and ‘lemons’ built so can the pc industry. Cars were notorious for breakdowns etc. As a kid you regularly saw a car broken down and/or needed to be towed. Today given population increases and more car manufacturers, do you see an increase in vehicke breakdowns in todays cars? Their reluability has gone through the roof, can we say the same for operating systems?

        Rowan, on reflection you’re probably correct. I think about all the times I read, “impossible, nothing is impossible” and have to come to the conclusion this is a paradox.
