I have compared the heart rate monitor with an exercise bike HR monitor and with my blood pressure cuff device. In all cases, they read the exact same value. As far as the sleep monitor goes, it is scary how accurate it is. The steps are a little off, but more accurate than other tracking devices that I've used.
Sorry, there was a problem. Please try again later.The heart rate is not very accurate, but the step counter is accurate enough if used correctly. I would say use this product as an indicator but don't trust it 100%
Sorry, there was a problem. Please try again later.It does a very good job of measuring steps when you are walking however for both steps and other activities it over estimates the calories burned (At least for me)
Sorry, there was a problem. Please try again later.I think it is pretty accurate. It is definitely more accurate than my phone. I have found it does not work right on an elliptical machine. I can do 1 mile on an elliptical and only get about .40miles on my fitbit. I have tried it on my ankle and that was even worse. That is the only place I have found it not work right. I did some research and found you just have to put it in manually when using an elliptical machine. Everything else it is great.
Sorry, there was a problem. Please try again later.This is quite accurate part from the heart Rate monitor which isn't to the T.
Sorry, there was a problem. Please try again later.There is no such product that is 100% accurate. I for one have found the Fitbit to be "pretty" accurate but it has its moments, especially during extreme exercise, it doesnt always seem to keep up. However, when I look at the app to see how I did, it looks like it did keep up. I totally recommend it.
Sorry, there was a problem. Please try again later.Pretty good, but not as good as, say, polar heart rate chest strap.
Sorry, there was a problem. Please try again later.I walk a 2 mile trail which has been measured and the Fitbit was accurate. Heart rate is accurate. Sleep, it says I hardly sleep at all. I am a light sleeper, but I don't think it is that bad. Stair climbing is accurate.
Sorry, there was a problem. Please try again later.This device is fairly accurate.
