Fitbit Heart Rate Tracers are Highly Inaccurate

Fitbit heart rate trackers are highly inaccurate devices as it has been claimed by so many sources. Fitbit Inc. company has been receiving complains about the devices from time to time. However the company has developed a deaf ear to these questions. Moreover, more escapism answers are also used to blind people: For instance the device is not intended to be a medical device nor scientific device but rather help people reach their health and fitness. This makes people to jump into conclusions that the device is inaccurate. This has been proven by many customers that have used the device. Furthermore the researches carried out against the device have clearly proved the device is inaccurate.

In the results which were tested from the heart rates of 43adults who are healthy, clearly showed the device is inaccurate. This was done by the researchers at California State Polytechnic. Their objective was to get the right information about the device. The researchers were creative in the way they carried their research in order to prove that the device is inaccurate. In a group of 43 adults, each was tested with Fitbit Pure Pulse heart rate monitor device together with the surge watches and the HR bands on each wrist.

Afterwards the same subjects were then tested with the BioHarness device. This device usually produces electrocardiogram (ECG) which records the heart bits against what Fitbit devices provides. Apparently from the results which were given in rest and exercises, it is clear that Fitbit miscalculated the heart rates by 20beats/minute. This was an average figure during the intensive exercises.

You can therefore deduce that the Pure Pulse trackers in the measure of the heart rates do not give accurate information especially during moderate-high exercises. Therefore it proves to be unreliable as far as health is concerned. This can be more hazardous to health when dealing with patients of heart disease.

Another study which was carried out by Lieff Cabraser targeting the Fitbit models which use the known pure pulse heart monitor- the Fitbit Blaze, Fitbit surge together with Fitbit surge. These devices indicated disparities in the results produced. The company failed to respond in time to the CNBC’s request for comment but the Fitbit statement which was posted by Gizmodo purposed at the study results indicates that this device gave out inaccurate readings.

Another study conducted in Ball State University which is located in Indiana proved that the device is indeed accurate.

There is no evidence that the device used has purported undergone the test for accuracy. Even if people are using this device there is no clear report from the manufacturer about the effectiveness of the device. Because the device has not undergone any test for accuracy, it then means that it is inaccurate.

The outcome of the test adds weight in a class action which has been filed against Fitbit is an indicator that these device accuracy needs to be questioned.

The company does not indicate whether the wrist differences affect the device accuracy. The dominant and non-dominant wrist usually gives different results when the tracker is worn on them. The dominant wrist usually decreases the sensitivity, this happens when counting steps leads to the reduction of any excess counting of the steps once the body is not moving. The non-dominant wrist increases the sensitivity of counting the steps and therefore it should reduce any under-counting. These inaccuracies come by because of the unspecified wrist to wear the tracker.

As stated by different research institutions, we can conclude beyond any reasonable doubt, that this device is indeed not accurate. This is evident from different sources with same complains about this device. In all the researches that were carried out, the response was always not clear from the company concerning their device. This device as much the company is concerned is not standard because its accuracy is not tested. When you buy it, you will never notice that it is not accurate unless the measurement from the device is compared by another device of the same purpose. Furthermore the device does not qualify for medical and scientific measurements. Therefore this device is inaccurate and hence not recommended to health measurements.
