Evie Ring Review (2024): Smart Ring Leaves Something to be Desired

If you’re on the hunt for one of the best fitness tracker rings on the market, the Evie Ring from Movano could be a solid choice. It’s a screenless, wearable fitness tracker that can record health and wellness metrics like sleep tracking, heart rate, blood oxygen levels, steps, calories, and distance. 

The Evie Ring also offers menstrual cycle tracking features and cycle predictions. I personally wasn’t impressed with these features, but I’ll touch on that later. In this Evie Ring review, I will share my experience after personally testing the smart ring for over a month. I think there are pros and cons, but overall, the Evie Ring left me feeling a bit underwhelmed. 

Fitness Professionals Test Over a Dozen Health Trackers 

While I’m not the most tech-savvy individual—I’m actually vehemently against adding more screen time to my life—I am a CPT with over six years of experience with one-on-one coaching in the strength and conditioning space. And I understand that behavior changes¹ are possible when wearing a fitness tracker. It can positively impact your daily activity, heart rate variability, and body composition. 

I tested the Movano Evie Ring for six weeks before giving my thoughts on the smart ring. I wore it pretty much every day for the entire six weeks: During work, rest, exercise, and overnight while I slept. There were only two or three nights I didn’t wear it sleeping. 

During my testing period, I assessed eight different categories including its general wearability, activity tracking capabilities, heart rate accuracy, battery life, and ease of use, to name a few. I was then tasked to score each category on a scale of 1 to 5 using our in-depth fitness equipment testing methodology.

Product Highlights

* Health tracking smart ring designed for women  * Tracks metrics associated with health, menstrual health, sleep quality, and activity  * Included: Evie ring and portable charger  * Available in 3 colors

Pros & Cons

Pros

• HSA/FSA eligible
• Free app and no membership subscription required
• Free sizing kit available
• Made with scratch resistant metal

Cons

• Not compatible with Android devices
• Evie app only available in the United States app store
• Sizes do not match traditional rings sizes
• Shorter battery life than competitors
• Evie app is poorly reviewed by customers
• Customers complain of inaccurate and lost data

Bottom Line

The Evie Ring is a smart health tracking ring aimed at women. It tracks menstrual health, general health, sleep, and activity. The initial price is similar to other ring style trackers and you don’t need to subscribe to a monthly membership in order to maintain access to your data. Customer reviews were poor, customers often found the data inaccurate and complained that the app would lose data, especially the sleep data.

A Quick Look at the Evie Ring

The Evie Ring is a small, lightweight, and screenless device that looks like an unassuming piece of jewelry rather than a fitness tracker. The Evie Ring was developed by Movano Health for women and folks assigned female at birth with period tracking capabilities, ovulation estimations, and fertile window estimations. 

The Evie Ring provides other health metrics like heart rate, step count, and sleep data. It’s water resistant up to one meter, has 4 days of battery life, and comes with a portable charging case and USB charger. There are no subscription fees, which means you’ll pay for the ring itself and nothing more. 

Additionally, the parent company Movano applied for the U.S. Food and Drug Administration (FDA) clearance for its pulse oximeter so it can be considered a medical-grade device. As of writing this review, it’s still under review. 

Before You Buy

• The Evie Ring is an HSA/FSA-eligible purchase. 
• The Evie Ring does not require a subscription, which means the companion Evie App is totally free to use. 
• If you’re looking for a smart ring with specific data to help you track menstrual cycles, fertility, or use as birth control, there are better options out there with more robust metrics. 

Is the Evie Ring Worth It?

The Evie Ring may be worth it for basic health and wellness tracking, but I’m not sure it’s worth it for anyone looking for detailed cycle tracking capabilities. I was pretty underwhelmed with the cycle tracking, mostly because the app lacks a key piece of information to provide a full picture of your cycle, namely body temperature values. 

That said, I like having a screenless and attractive wearable device to track steps and general activity. I also appreciate that Evie doesn’t tack on a monthly subscription fee to use the app. For reference, the Oura Ring has a monthly subscription fee, but other rings (like the Samsung Galaxy Ring, Ultrahuman Ring Air, and RingConn Smart Ring do not have membership fees).

Wearing the Evie Ring

I’m a certified personal trainer and understand the benefits of wearing a fitness tracker. I’ve seen many clients benefit from wearing an Apple Watch or one of the best Fitbit devices, but I tend to get obsessive with health data and graphs. 

That said, a nice-looking, screenless device is pretty much the extent of my willingness to use a tracker. I can’t stand being blown up with notifications and alerts about my heart rate, stress levels, or step count. 

But the good news is, the Evie Ring is not that. It’s a fashionable ring that discreetly syncs to your iPhone with health data ready for you when you want to look at it. The Evie app can send you notifications, but I have that all turned off.

Comfort and Aesthetics

If I’m being honest, the best thing about the Evie Ring is the way it looks. I had the free sizing kit sent to my house before choosing my size and color. Evie doesn’t have traditional ring sizes, so you’ll probably need the kit to be sure. There are also three colors to choose from: rose gold, gold, and silver. 

For our general wear category, I scored the ring 5 out of 5 stars. It has a nice finish. The gold option I chose matches my other gold jewelry and doesn’t look completely bogus to wear to a formal event (I went to two weddings during my testing period). 

It’s also very comfortable and has an open design that can flex with finger swelling. The brand notes that the index finger will provide the most accurate results, but also mentions middle and ring finger are OK too. The only thing that’s annoying is taking it on and off for lifting sessions—I don’t suggest wearing any rings while lifting with a barbell. 

Health Tracking Capabilities 

The Evie Ring can track all your basic health metrics like heart rate, step count, active minutes, distance traveled, and calories burned. 

The app will also show you other data points like resting heart rate, heart rate variability, skin temperature variation average, respiration rate, and blood oxygen, but it’s all within the sleep data. And many of these metrics are shown as averages. 

Below I’ll break down the different types of things you can track. 

Fitness Tracking

The Evie Ring is fairly rudimentary when it comes to fitness tracking. You can see data on your steps, distance, and calories burned. You’ll also be able to see the number of active minutes per day, but I find this feature rather troublesome because the Evie Ring doesn’t have automatic workout detection. 

Because it lacks auto detection, I will often forget to hit “track a workout” before heading out for my 45-minute walk before work. If I haven’t asked the app to track, the ring only senses that I’ve had 12 active minutes (sometimes even less) at the end of a walk. I’ve also played around with this for lifting sessions and it’s the same story. 

The “track a workout” feature is also quite limited with no way to select different modes of exercise. I assume the app thinks I’m either walking or running and that’s about it, which I find annoying and problematic. 

Sleep Tracking

Sleep tracking is where the Evie Ring may redeem itself a bit. Each morning, I wake to a graph of my sleep cycles and how many minutes were spent in each: REM, light, and deep sleep. 

For those of you familiar with Whoop straps and the Oura Ring, you won’t get a sleep score with this device. I actually like that, but some folks might not. 

RELATED: Whoop 4.0 Review

It falls short in “sleep vitals” data, which are all presented as averages. You can’t get a full breakdown of your heart rate during the night or body temperature. Everything is averaged, which I don’t always find helpful. 

It’s also worth noting I’m someone who sleeps with mouth tape (I know, so trendy of me!) because I have adult braces and my lips don’t naturally hold a tight seal anymore. I notice that when I forget to apply tape over my mouth, I don’t receive a blood oxygen percentage—it’s just a blank box and it’s happened multiple times. This makes me think that nasal breathing may be the only way for the Evie Ring to capture that SpO2. 

Cycle Tracking

Cycle tracking is more than just menstruation—that’s just one piece of the puzzle, whether you’re trying to get pregnant or not.  

From my experience, the Evie app is more robust than the Apple Health for cycle tracking because you can log your energy levels, mood, and vaginal discharge all month long. And then during your period you can log your flow and other symptoms like spotting and cramping.

Where I think it falls short: It doesn’t include skin temperature tracking alongside all your other cycle data. Your skin temperature variations are only seen in the sleep data tab. And a quick reminder from the section above: It’s an average. The Evie App doesn’t report an actual temperature, it just provides how much your temperature deviated from the average. It will display something like -0.2 or +0.1, not a temperature value.

I don’t like this method because it’s not giving you the raw data, and if you start wearing Evie in the middle of your cycle, your baseline temperature will be different than if you started wearing it at the beginning of your cycle. It doesn’t make me feel like it’s personalized enough. Why not just show us our body temperature? 

Battery Life and Connectivity 

The brand says a single charge of the Evie Ring can last for four days with continuous use and logging one workout per day. From my personal experience, that’s true. The brand notes short charging sessions to top off the battery can help you avoid long charging sessions. Although, I noticed it only took about an hour to get a full charge from about 25% battery. I’ve done both, and either method seems fine. 

The battery life on smart rings is generally longer than smartwatches (like the Apple Watch), but our team has used fitness rings that can last a full week on one charge. Compared to a smartwatch, the four-day battery life is excellent, but in an ideal world, it would be a full week. I scored the battery life 4.5 out of 5 stars. 

RELATED: Apple Watch Series 6 Review

The Evie Ring is only compatible with iOS 16 and higher, which means the iPhone 8 or newer. You’re out of luck if you use an Android device. 

Keep in mind the ring only syncs with the Evie App. There was no way to tie into my Apple Health, or any other health and fitness app for that matter. For this reason, I scored the Evie Ring 3 out of 5 stars for the connectivity category. To receive a higher score, the Evie Ring would need additional opportunities to sync with other popular apps. Our highest scores in this category are reserved for devices with built-in GPS tracking. 

Ease of Use

Evie is pretty easy to use, but I scored it a 3 out of 5 stars because the app lacks functionality and detailed information. I also don’t like the fact it doesn’t sync with my Apple Health (however, it does make for a streamlined experience). 

On the home screen of the app, you’ll see a circular chart with all of the basic fitness tracking metrics: sleep, activity minutes, step count, and calories. You can get more details on each category by clicking the wheel or using the menu on the bottom. 

While I don’t have a problem with using the app, I found it doesn’t provide enough information. Here are a few examples of what I mean: 

• You can track a workout, but there is no way to choose what type of activity you’re doing. The app can’t do anything else while you’re tracking a workout and you have to select a preset amount of time, you can’t tell the app when you’re done. 
• When you track a workout, you can’t see your heart rate or any other metrics in real time, the app is locked on a countdown timer screen. 
• You can perform a “spot check” but it only detects your heart rate and blood oxygen level (not skin temperature). 
• You can view your sleep vitals every morning but it’s all based on averages (including RHR average, HRV average, SpO2 max, respiration rate average, and skin temperature variation average). 
• The skin temperature average doesn’t provide an actual temperature (like 98.2 degrees) it just displays your variance from the average (-0.2 or +0.1). 

Another thing to note, the ring itself won’t tell you when the battery is dying. It doesn’t flash the LED lights or buzz. You’ll have to view the battery percentage at the top left corner in the Evie app.

Product Highlights

• Measures your heart rate, oxygen saturation levels, and skin temperature
• Over time, it can track your sleep patterns and suggest improvements
• Battery lasts 7 days and can fully charge in 20 minutes
• Can help you find your balance between activity and recovery
• Water resistant up to 100 m

Pros & Cons

Pros

• Long battery life
• Fast charging
• No membership required

Cons

• May develop scratches with daily wear
• Limited statistics without membership
• Comparably expensive

Bottom Line

If you are looking for a fitness tracker that is more subtle and sleek than a traditional wrist tracker, the Oura Ring is a great alternative option.

The best smart rings track all of the basics including heart rate, resting heart rate (RHR), heart rate variability (HRV), and blood oxygen levels (SpO2). We also expect to be able to track steps, calories, and distance. 

All three of these trackers can do that: Evie Ring, Samsung Galaxy Ring, and the Oura Ring. There are a few things each does well that I want to point out: 

• The Evie Ring is the most affordable and most jewelry-like option. It also does not require a membership to use the app. 
• The Samsung Galaxy Ring uses skin temperature as part of the cycle tracking feature. Although, you will need to go into the app and manually turn on the temperature sensor to use this feature. You can read more about that in our Samsung Galaxy Ring review. 
• The Oura Ring is the superior choice for anyone focused on workout metrics. It allows you to choose from over 50 different types of exercise profiles—you can view your stats on the phone in real time, too. 

Customer Experience 

The Evie Ring has a one-year limited warranty that covers defects in materials and workmanship, which is the brand’s way of saying it doesn’t cover normal wear and tear. 

You’ll have a 30-day window from the purchase date to make an exchange or return. Returns and exchanges go through a third-party service called Loop Returns. Although the return instructions are not entirely clear, my understanding is that you’ll need to email support@eviering.com to get a return order number so you can start the process with Loop Returns. 

It’s also worth noting I couldn’t find a company phone number or business hours. It’s really not ideal to see that a customer with concerns has very few (really, just one) method of contacting the company. For this reason, customer experience earns a 2.5 out of 5 stars. 

Customer Reviews

At the time of writing this Evie Ring review, I found very few customer reviews online and absolutely none on the Evie website. On Trustpilot, there are currently eight customer reviews with an incredibly poor average rating of 2.3 out of 5 stars. 

Multiple reviews say the customer service is non-existent and another notes the ring totally died after just a few months of use. Additionally, there are varying reviews on TikTok about the ring’s effectiveness, with some folks loving it and some really not. 

Final Verdict of Our Evie Ring Review

Although I was sort of underwhelmed with the women’s health tracking features, lack of details, and inability to track different types of workouts, I actually don’t dislike the Evie Ring. I might have had high expectations, but I’m wearing the Evie Ring as I write this review.

I like having a passive activity tracker without a screen. It fits my lifestyle and my quest to keep screen time to a minimum (yes, I work at a computer, but you know what I mean). I also like tracking my sleep and seeing how much deep sleep I get each night.  

The Evie Ring is not perfect and I think it would help with cycle tracking and estimating fertility if skin temperature could be added to the “spot check” feature so you can manually check those stats when you wake up each day. However, I don’t think the Evie Ring is too far away from being great. I honestly look forward to testing future iterations.
