Anyone know what to do to make the Fitbit blaze measure heartrate more accurately. When I self count (which I did several times today checking), my counting is in line with what my bike says (above you can see the Blaze says 61 while my bike shows 124). My resting heart rate while sleeping is 72; so, 61 really shouldn't be possible while in the middle of exercising.
I noticed yesterday it said my average heart rate was 69 while biking (no way this was the case). When my bike says anything over 130 and I check the heart rate isn't even showing up on the Blaze half the time- at onepoint my bike said 137-143 and I self counted 35 beats in 15 seconds- so, in line with the bike, but Blaze said 107.
I've tried restarting, I switched wrists, tightened, loosened, put it on so the watch face is on the underside of wrist... Everything I can think. The watch is fully charged right now.

Hi @KayZ @Michmich55! Great to see you in the Fitbit Community Forums! 🙂
@KayZ, As you mentioned, whenever you're exercising it's important for you to wear your tracker higher on your wrist and a little bit tighter to prevent the heart rate sensor to lose contact with your sking making it to sense your heart rate inaccurately. Just for anyone else who might need this information, keep in mind the following recomendations:
For all-day wear when you’re not exercising, your tracker should usually rest a finger’s width below your wrist bone and lay flat, just as you would wear a watch. Fitbit’s PurePulse heart rate tracking system is designed to be most accurate when the tracker is worn on the top of your wrist.
For improved heart rate accuracy keep these tips in mind:
- Experiment with wearing the tracker higher on your wrist during exercise. Because blood flow in your arm increases the farther up you go, moving the tracker up a couple inches can improve the heart rate signal. Also, many exercises such as push-ups cause you to bend your wrist frequently, which is more likely to interfere with the heart rate signal if the tracker is lower on your wrist.
- Do not wear your tracker too tight; a tight band restricts blood flow, potentially affecting the heart rate signal. That being said, the tracker should also be slightly tighter (snug but not constricting) during exercise than during all-day wear.
- With high-intensity interval training, P90X, boxing, or other activities where your wrist is moving vigorously and non-rhythmically, the movement may prevent the sensor from finding an accurate heart rate. Similarly, with exercises such as weight lifting or rowing, your wrist muscles may flex in such a way that the band tightens and loosens during exercise. Try relaxing your wrist and staying still briefly (about 10 seconds), after which you should see an accurate heart rate reading. Note that your tracker will still provide accurate calorie burn readings during these types of exercise by analyzing your heart rate trends over the course of the workout.
Hope this helps!

The same happened to me! This simply does not work properly. Just bought the Samsung Gear Fit2 pro and will see if that works better.
