Certain exercises produce inaccurate heart rate readings on the Apple Watch
posted by Alan F. / Oct 24, 2015, 2:18 PM
One P90X user had a Polar heart rate strap on, with the Polar watch on one wrist, and the Apple Watch on the other. The Polar device showed a heart rate above 160 during the exercise, while the Apple Watch showed a rate of 70-80bpm. Apple has sent replacement watches to users with this issue, but that has not cleared up the heart rate inaccuracies.
The Apple Watch uses a method called photoplethysmography that measures blood flow in the wrist, to determine a user's heart rate. Apple's own website lists certain activities that could produce inconsistent results with this process. Activities like tennis and boxing will produce inconsistent and inaccurate heart rate readings on the Apple Watch, because those feature movements that are "irregular." Not surprisingly, exercises that have a certain rhythm, like cycling, or running, will work better with the watch. Still, some users who are doing exercises like running and walking outdoors, both of which are recommended by Apple's workout app, are having the same issues with their Apple Watch.
No word yet from Apple about this. Since they have supposedly sent out replacement watches to some, they are obviously aware of the problem. In addition, you might recall that earlier this year, it was discovered that Apple Watch users with a tattoo on their wrist could not get a heart rate reading from the watch since the ink blocks the sensors on the device. Some claim that moving the watch up toward the elbow will produce a more accurate reading, but Apple does not recommend doing this since it built the watch specifically to be used on the wrist.

I noticed this when I went running with my girlfriend's Watch the other day where it gave me readings up to 50% too high at times, based on my normal range. The other thing I noticed was a lot of lag when switching between apps and screens, something the first Samsung smartwatches were rightfully slammed for.... Inexcusable in 2015 and at this pricepoint though.

Apple today announced that only 9 people were affected by this.

How could they possibly now that exactly? The government of my country told my people in '90 that 4 people died in the Mineriada Riot but in reality thousands died. Don't belive everything they say.

Inexcusable to say it because of certain exercises cause of how you moving your rist. Come on now who checks their heart rate while throwing punches all people working out usually stop moving while they check their heart rate.

No wrist bound heart rate monitor is going to be that accurate with things that involve large amounts of movement, not an apple problem here.

Fitbit and a few others don't seem to be having this kind of problem...

No that can't be right, remember Apple products 'just work' and they don't lag. In addition, Apple always implements features just right or rather in a perfect way as compared to others... Yeah, right.

i have the apple watch and this is true, i excerise with it and that was the main reason why i bought it to track the calories and heart rate. when im using it to work out sometimes it jumps from 150 to 70 or something when im totally out of breath so it can't be accurate. i hope they fix this or give us an exchange because it was expensive and like i said it was my main reason to buy an apple watch
