Oura Ring Vs Fitbit Charge 6

Whether it is the Oura Ring or Fitbit Charge 6, both IoT devices are focused on the health and fitness benefits of the users. When the Fitbit models have shown significant improvements in terms of features in the past couple of years, the Oura Ring seems to be stuck with the same feature list. Although Oura Ring developers claim to refine the features with every firmware update, users are refraining because of its high price tag [$299 – $549] and restricted feature list. 

So let us share a clear view of the Oura Ring vs Fitbit Charge 6 comparison for your better understanding. 

Oura Ring Vs Fitbit Charge 6: Fundamental Differences

The fundamental difference between the Oura Ring and Fitbit Charge 6 is that the Oura Ring is a smart ‘ring’, and the Fitbit Charge 6 is a wristwatch model. Hence, when it comes to the shape, design, and weight, there are huge differences between these two smart devices. 

Oura Ring

The Oura Ring Gen 3 is a closed traditional ring model embedded with multiple sensors that track health and fitness metrics. This titanium forged model weighs between 4 – 6 g [depending on size] and is easy to wear 24/7. 

Fitbit Charge 6

Fitbit Charge 6 is the new Fitbit model, available in the market. This smartwatch weighs 30 g and comes with an Infinity band (small and large). Henceforth, there is no sizing issue with this smartwatch. However, some users may feel uncomfortable wearing a smartwatch 24/7. Wearing a Fitbit Charge 6 for 24/7 can attract unnecessary attention.
