Is there any activity tracker (For the wrist, like FitBit or JawBone) which measures the heart rate in addition to all the other measurements?
They all seem just to measure insignificant statistics.
There are quite a few heart rate monitor fitness trackers coming soon to the market. I'm sure many of us (including me) are anxiously awaiting something that can accurately measure calorie expenditure, rather than relying on a pedometer. Obviously, nobody wants to have to inconveniently strap a heart rate monitor around their chest.
Here are some options you may keep your eye on for releases in the near future:
Already on the market (or almost on the market) are some other watches/wristbands that might suit your needs, such as:
Another option is the Withings Pulse, which is a little widget that doesn't really fall into any of these categories:
And maybe somewhere way down the line, you'll be able to have a smart contact lens that watches your heart rate as well, such as:
Apple Watch heart rate monitor is surprisingly accurate for not having to wear a rib cage band. Especially with the watchOS 3, where there is a dedicated app for heart rate monitoring. Try it! I can't live without it now that the Apple Watch is swim-proof.
As ZOD has indicated, for a more accurate record of heart rate, the standard practice is to wear a heart rate monitor belt paired with a wrist watch receiver. Polar heart rate monitors are a leader in that industry.
