The 5 Biggest Oura Ring Competitors Revealed

Oura, based out of Oulu, Finland, is a company that manufacturers and distributes a smart ring used to track sleep and physical activities.

Its rings, which are currently on their third iteration and made of titanium, utilize optical heart-rate monitoring to capture a person’s biometric data.

Oura measures a variety of data points, including sleep duration, heart rate, movements such as steps taken, or one’s body temperature.

It then creates a dedicated profile and transmits that data to an accompanying app, which is available for both Android and iOS devices, via Bluetooth.

Oura was founded in 2013 by Kari Kivela, Markku Koskela, and Petteri Lahtela. Around 450 people are employed by the company. Moreover, it has raised $148.3 million in funding according to Crunchbase. Lastly, a total of 318,000 people follow the company on Instagram. 

The methodology with which the competitors of Oura are ranked is based on publicly available data. Since Oura as well as most of its competitors remain in private ownership, data on revenue is hard to come by.

Instead, its competition is ranked based on three key factors, namely how many people they employ, how much money they have raised, as well as the number of Instagram followers they have. Instagram tends to be the most relevant organic acquisition channel for many direct-to-consumer (DTC) brands, hence other social media platforms are excluded from this analysis.

Additionally, we only look into brands that sell health-oriented smart rings to ensure comparability. The Honorable Mentions section consequently entails companies that tackle other use cases.

This analysis should not be taken as a recommendation to make a particular purchase. It is merely a summary of all the competition that Oura faces as of today.

So, without further ado, let’s take a closer look at the top five competitors of Oura.

Not much info is made available about the company which is operated out of China. No funding has been raised today and LinkedIn cites around five employees. The company, furthermore, only has around 300 followers on Instagram.

5. Movano

Honorable Mentions

Smart rings are used for a variety of purposes. While the Oura ring is certainly one, if not the most famous product in the space, there are still companies that focus on tackling other problems.

One of those other big use cases is payments. Smart rings such as McLear’s RingPay or HECERE’s NFC Ring enable owners to pay at card terminals that are compatible with NFC technology.

Some rings, like the ORII Smart Ring, even allow you to accept and conduct telephone calls while using the ring as a speaker.

There are, furthermore, rings made for car owners and specifically Tesla drivers. Products such as the CNICK Tesla Smart Ring or COLMO Model 3 Smart Ring allow users to replace their Tesla key card and open their cars with the ring.

In general, any ring that offers NFC technology can technically be programmed for a multitude of use cases such as creating business cards or accessing encoded locations.


In summary, one can conclude that Oura remains to be the undisputed market leader in the smart ring industry, especially when it comes to health-focused products.  

It, by far, employs the greatest number of people and garners the most eyeballs (as exemplified through its Instagram following).

However, a few competitors, such as Circular or Movano, are gunning for its leadership position with millions in backing and major upcoming product launches.
