Movano has started taking orders for Evie Ring. The $269 device is on the cusp of becoming one of the first consumer wearables to receive FDA clearance. By eliminating a monthly subscription, Evie Ring is a more affordable alternative to Oura ring, while monitoring much the same metrics.
A number of other companies are working on their own smart ring solutions. And it’s not just lesser known names. Apple is a company that has figured in this conversation for years now, but with little to show. Other brands have started to register smart ring patents, too.
One of these is Fitbit. With Google’s money behind it, perhaps we might finally see a smart ring from the San Francisco wearables pioneer. Another is Oppo. The company has registered a smart ring patent with the Chinese authorities last year. Samsung is amongst these, as well.

We are not sure when and if we will see smart rings from these companies. Just because they have filed patents does not mean they will produce working devices. If nothing else, it does show is that they are thinking of exploring the smart ring space. But there are already a few quite good options out there such as RingConn and Ultrahuman.
Movano’s smart ring is called Evie
The Movano ring was originally demoed at CES 2022 in Las Vegas. Another demo followed at CES 2023 earlier this year.
This is the first such product from this health tech company. The ring is called Evie. As its name implies, this is a device designed primarily for women.
Evie is actually a play on the word “evidence”. Meaning, the ring will deliver trusted evidence. To this end the company is in the process of gaining approval from the US Food and Drug Administration (FDA). The goal is to ultimately for Evie ring to have Class II designation as a medical device.
As far as what type of evidence, Evie is able to monitor a slew of health metrics. This includes activity, sleep, heart rate, heart rate variability (HRV), sleep, restoration, temperature, blood oxygen, steps, calories, menstrual cycle, ovulation and mood.
The accompanying smartphone app spits out easy to understand actionable insights on the data the ring collects. The idea is to link the cause and effect of individual metrics. For example, you’ll be able to know how your exercise habits impact your sleep patterns, HRV and more. That way you’ll be able to take “a more proactive approach to mitigating the risks of chronic disease.”
However, the company’s ambitions do not end there. In an interview a few months ago, it was revealed that the ring might eventually be able to monitor glucose non-invasively and provide cuff-less blood pressure information. The proprietary radio frequency technology that is used to obtain this type of data is undergoing clinical trials. If this is proven successful, it will be a game-changer.
The ring itself is circular, but it is not a solid circle. There’s a small gap. This appears to be more a design characteristic that allows the ring to expand a little bit over the knuckle. It should also help if your finger swells. As far as build, Evie is made of metal with a resin inner section.
Users are able to choose between silver, gold and rose gold finishes. All of these come in sizes between 5 and 12.
As far as battery life, this comes in at around 4 days. A one hour charge is enough to refuel the device. You also get a nifty charging case that you can carry with you. This is good for up to 10 full charges.
Back in August the Evie team has submitted their first 510(k) application to the U.S. Food and Drug Administration (FDA) for medical device clearance. This application pertains to Evie’s pulse oximeter, which includes heart rate and blood oxygen saturation (SpO2) data. The submission has successfully passed the initial review for completeness and is now under full review by the FDA.
The Evie Ring has shown promising results in clinical trials, exceeding FDA standards. When compared with arterial blood gas data, the ring’s data accuracy resulted in an approximate 2% margin of error, well below the FDA guidance of 3.5% for SpO2. In terms of pulse rate accuracy, the Evie Ring demonstrated a margin of error of just 1 beat per minute (BPM), surpassing the FDA’s requirements.
The Evie team expects to receive a decision from the FDA on their pulse oximeter submission within six months from their submission date. If the Evie Ring receives FDA clearance as a medical device, it would be one of the first consumer wearables to achieve this status. This would not only validate the ring’s accuracy standards but also position Evie as a trusted device for both users and healthcare professionals.
However, it’s important to note that FDA clearance does not guarantee insurance coverage for the device initially. The Evie team is actively working towards making insurance coverage a possibility in the future.
Movano Evie smart ring: Price, availability
Now we get to the cost. The good news is that there is no subscription. Evie’s main competitor Oura Ring will set you back around $300. But on top of this you need to fork out for a $6 monthly subscription (after the initial six months). Regardless of the FDA’s decision, there will just be the upfront cost of Evie which will be $269.
Ring availability has begun in the US on eviering.com, while Europe and Australia should follow soon after. Orders placed today will ship in January 2024.
