A few months earlier, a dear friend of mine suggested I try the latest Whoop 4.0 band for tracking my health, activities, and workouts. Though my Evie Ring had already done that for me for the past few months, I was intrigued by the stylish band that looked nothing like a fitness gadget!
After wearing them for a couple of months, it took me no time to decide which one I needed to stick with. You can find out which gadget I chose and why in the next few sections.
My Experience With Evie Ring And Whoop 4.0
Though I enjoyed wearing them both thoroughly to monitor my overall health and fitness, I found the Evie Ring a better option than the Whoop 4.0 band. While both are screenless and worn on different organs, the Evie Ring wins over Whoop 4.0 in terms of battery life, price, and features.
While I do not deny the accuracy of the Whoop 4.0 band, I find Evie covering more health metrics that are sufficient for me at an affordable price. The following comparison will further explain why I am inclined to the Evie Ring.
Women-Centric Features
Being a female myself, I wanted a wearable that could monitor my hormonal changes and menstrual phases. With Evie, I simply log in my period dates, and it further analyzes my period cycle, ovulation period, etc.
My experience with Whoop’s women-centric features was better than expected. When I started wearing the Whoop 4.0 band, I tested it for tracking my period and actually liked it. Just like the Evie Ring, I logged in my period date and found valuable information on Whoop’s Menstrual Cycle Insight. It told me how my menstrual phase is affecting my sleep and strain and provided recommendations on training and workouts.
Whoop has toggles for pregnancy, trying to conceive, etc., that were missing in the Evie Ring. Moreover, it has a Community platform where pregnant women can connect to new moms-to-be and share their experiences.
I am amazed that despite being a fitness tracker, Whoop 6.0 covers more women-related metrics. Though the Evie Ring claims to be a women-oriented health gadget, it is still far behind the gender-neutral fitness gadgets. For example, the Evie Ring tracks the skin temperature but doesn’t use this information to predict ovulation and fertility days.
Evie Ring should consider adding more female-oriented metrics if it really wants to be the flag-bearer of women-centric rings. As of now, I feel Evie Ring needs to work a lot to improve itself.
Though the Whoop 4.0 band outweighs the Evie Ring in terms of women-related metrics, Evie gives almost similar information at a lesser price. However, I am disappointed that Evie Ring has not included the pregnancy feature yet. Moreover, they have said that the app will soon be compatible with Android, but there has been no announcement about it yet.
While the Evie Ring has not announced the addition of the pregnancy feature yet, it has a high chance of being launched in the upcoming versions. Since the Evie Ring has a long history of delaying things, I hope that the wait will be worth it.
Battery Life & Charging
The good thing is that both gadgets have advanced charging capabilities. I charge my Evie Ring using the portable charging case, and I charge my Whoop band using the Whoop battery pack.
| Charging Details | Evie Ring | Whoop 4.0 |
|---|---|---|
| Official Battery Life | 4+ days of battery life (varies based on usage) | 5 days |
| My Observed Battery Life | 3-4 days | 4 days |
| Official Charging Time | 60 mins | 2-2.5 hours |
| My Observed Charging Time | 60-70 mins | 2.5-3 hours |
The Evie Ring’s charging case holds up to 10 charges and acts as an accessory box. Given my habit of forgetting things, my chances of losing the Evie Ring are quite low with its charging box.
Unlike the Evie Ring, I can charge my Whoop band while wearing it by sliding the Battery Pack onto the band. So, whenever the battery gets low, I simply put it on and carry on my work without the need to remove it.
However, once the band’s battery gets fully charged, I have to charge the Battery Pack using a USB-C cable. At least I have the freedom to charge my Evie Ring case once to get the next 9-10 charging durations, unlike the Whoop charging batteries that require charging every other time.
The Whoop charging option is good for those who like to track their metrics 24/7. Since the 4.0 band is waterproof, I have charged it while doing dishes or taking a shower, but it’s risky, and losing it can cost me $49 worth of replacement. So, I charge it very attentively while at work.
The LED battery indicator light is positioned on the top of the pack, so it’s quite easier to check whether it is charging or not. However, I have to rely on my phone to know its exact charging percentage.
Again, the Whoop 4.0 takes more time to charge than the Evie Ring in terms of duration. My Whoop band’s charge lasts for 4 days, and so does the Evie Ring’s charge. Moreover, it takes me only 60-70 minutes to recharge the Evie Ring.
The Whoop 4.0 takes almost 3 hours to charge itself completely, and that’s too exhausting for anyone to bear. So, I find charging the Evie Ring more easier than the Whoop 4.0 tracker.
Design & Colors
I own a Silver colored Evie Ring and a Red-strapped Whoop 4.0 tracker. Though Evie has two more colors- Gold and Rose Gold, I found the Silver one more aesthetic and suitable with my daily outfits.
For once, I had double thoughts about having the Rose Gold Evie Ring as it looked more feminine and beautiful. However, it got out of stock after some time. It happens every time with me!
Anyway, I waited for a few more days, but it was not available. So, after a lot of thought and juggling, I opted for the silver one! I guess the universe wanted me to have that silver ring, and it turned out to be the best decision.
The design of the Evie ring is unique. It is a round-shaped ring with two open edges. Thus, the design suits me perfectly as I can wear it and slightly adjust it to fit my fingers while having swollen fingers.
The Whoop 4.0 band, on the other hand, looks like a plain and regular band. However, I can wear it not just on my wrist but also with my exercise clothes or armband. I liked the flexibility that it offers.
What I liked the most about the Whoop band is that it has lots of color options. Despite its simple knitted band design, the Whoop 4.0 band stands out in the crowd.
I have the freedom to customize my band with different colors of SuperKnit luxe straps or ProKnit straps, hooks, clasps, and sliders. Moreover, it allows personalized engraving for just $25, and I love it!
My verdict is that both fitness trackers are good and sophisticated in terms of design. However, the Whoop 4.0 offers more color options than the Evie Ring.
Material, Comfort & Durability
| Specifications | Evie Ring | Whoop 4.0 |
|---|---|---|
| Weight | 3.2-3.7g (depending on ring size) | 11.3 grams |
| Dimension | 8mm wide; 3mm thick | Sensor: 25.0 mm x 35.97 mm x 10.1 mm Band Length: 24 cm |
| Material | Liquidmetal and Titanium PVD Coating | Band: 52% polyamide, 41% polyester, 7% elastane Clasp: Stainless Steel Hook: Stainless Steel Fast Link™: Stainless Steel Sensor Body: Titanium |
One thing that makes the Whoop 4.0 fitness tracker different from the Evie Ring, in fact, all other smart rings, is that it can be worn in different places—on the wrist, arm, bralette, boxer, training apparel, etc. So, I have the freedom to choose where to wear it according to my comfort. For example, I wear it under my bralette or wrap it around my arm while doing intense exercises.
However, I find it a bit exhausting to keep changing the tracker every time. If I wear the band for long durations, I get sweat marks on it. I have no such issues with the Evie Ring, though. The Evie Ring’s durability is up to the mark, but it is not scratch-resistant.
I got a scratch while I was cleaning my garden. The Whoop bands are more durable than their buckle, which I have replaced many times. Plus, it is affordable to customize the Whoop band. Unfortunately, I can’t do it with the Evie Ring.
The open-ended design of the Evie Ring is helpful in wearing and removing it from the finger, specifically when I have hormonal changes. Though the Whoop band is also very comfortable to wear, I had a lot of trouble with the Whoop’s buckle, as it kept falling many times. Since Evie is a simple ring, these issues in my ring do not bother me.
So, I am more comfortable wearing the Evie Ring than the Whoop 4.0 band.
Sensors
| Sensors | Evie Ring | Whoop 4.0 |
|---|---|---|
| Red LEDs | Yes | Yes |
| Green LEDs | Yes | Yes |
| Infrared LEDs | Yes | Yes |
| Infrared PPG sensors | Yes | Yes |
| Skin Temperature sensors | Yes | Yes |
| Photodiodes | Yes | Yes |
| 3D Accelerometer | Yes | Yes |
| Gyroscope | No | Yes |
Both the Evie Ring and Whoop 4.0 tracker have similar sensors. Thus, they track almost similar health metrics and provide data accordingly. Despite having the same sensors, Evie Ring lacks tracking physical strain like Whoop 4.0. Evie can work on its sensor efficiency by including more metrics like the Whoop band.
Accuracy
Though the Evie Ring is not a medical-grade device, its accuracy in tracking SpO2 and Heart Rate is quite remarkable and exceeds the FDA-approved margin error.
- SpO2 (2.3% margin of error compared to the FDA’s approved 3.5% error margin)
- Heart Rate (1 BPM margin of error compared to the FDA’s approved 2 BPM error margin).
The Whoop 4.0 tracker takes a week to initialize and record a baseline. So, I had trouble getting accurate results in the initial days. However, it started tracking cardio activities like training runs quite accurately later.
On the other hand, though the Evie Ring measures the baseline for HR, HRV, and RR, it doesn’t mention how much time it takes to measure all the metrics. While it shows the average skin temperature variation, it doesn’t calculate a baseline for it. Hence, more clarification on this can help users get more accurate results.
The readings for HRV, RHR, and Sleep were almost near Evie’s readings. However, I found Evie’s tracking more accurate in the sleep stages than Whoop 4.0. Though the Whoop tracker doesn’t track many metrics, its accuracy in tracking training sessions was satisfactory.

While both track sleep in an elaborate way, Whoop 4.0 also gives recommendations on when to sleep or wake to complete the sleep cycle. It also has an alarm feature that wakes me up when I have completed my sleeping hours.
Whoop 4.0’s Strain Score measures the impact of my training activities on my vitals and then scores, mentioning whether I am ready for the next workout or need more rest. The Evie Ring does not have the Strain Score or anything that directly suggests physical recovery.
Whoop 4.0 also gives specific Stress Scores by using real-time HR and HRV and suggests breathwork sessions. Meanwhile, I have to go through my HRV, RHR, Sleep, RR, etc., to determine my stress level in the Evie Ring app.
Data Sharing
When it comes to health data sharing, both Evie and Whoop share data that can be used for medical advice. Though they don’t claim to generate medically approved data, the readings can be considered.
So, whenever I need to see my doctor, I have enough health data from the Evie Ring on a weekly or monthly basis to get a thorough examination. Whoop 4.0 extends the data sharing further.
I joined the Whoop Community after buying the subscription plan. It is a platform where I can create or join groups and share my health stats. I love competing with my Whoop Community friends, exchanging helpful tips, sharing data, etc. It also allows users to share health reports, though it is not medically certified. I usually use this feature on my photos and videos and post them on social media. Isn’t it cool?
Companion Apps

The Evie app is quite easy to use and understand. It has multiple slides, a circular representation of overall well-being, set personalized goals, and the ability to log essential body data, such as menstrual cycle and mood.
I get a quick recap of how much I am progressing on my personalized goals or how I spent my day on the Today Tab. Be it wellness trends over time or educational insights correlating different data, I get a lot of valuable information on it.
I can see important data like daily performance scores, health metrics, real-time stress levels, trends, etc., based on my overall body activities on the Whoop app.
I use the AI-powered Whoop Coach to get real-time answers for custom performance coaching. The app shows personalized insights and actionable feedback based on my overall data and goals, and its monthly feature updates keep it working quite smoothly.
The Whoop app also offers podcasts and blogs that are quite interesting and helpful to build healthy habits.
While both apps provide elaborate data, I find Whoop’s app a bit more overwhelming than the Evie app. The Whoop app has lots of graphs that are not so easy to decipher. Other than that, it does not have an eye-catching slide layout like the Evie app. So, sticking with it for longer durations is not much I prefer.
Prices & Subscription
I find the Whoop 4.0 fitness tracker really expensive compared to the Evie Ring in several aspects and that is one of the reasons that I prefer the Evie Ring over Whoop. I bought my Evie Ring for $269, but it was a one-time deal.
| Pricing Details | Evie Ring | Whoop 4.0 |
|---|---|---|
| Official Price | $269 | N/A |
| Subscription | Free | Free for the first month $30/month $239/year $399 for 24 months |
| Availability | US only | Worldwide |
Unlike the Whoop 4.0 band, Evie Ring’s price also included complete access to its app. So, I didn’t have to worry about Evie’s subscription or having additional accessories for the ring!
There is no separate price for the Whoop 4.0 band. It is included with the subscription price. Once you buy it with a subscription, it delivers the battery and Onyx SuperKnit band, including a lifetime warranty. I bought a few Onyx SuperKnit bands separately. The price range starts from $49.
Whoop 4.0 requires a subscription or membership to access its features. Though new users can access its one-month free trial, it costs me $239 annually and $399 for 24 months. I had bought extra knuckles and bands as well.
Compared to the prices, Whoop is way more expensive than the Evie Ring, and I am not interested in paying this much for a faceless gadget. Also, I didn’t find much difference in their features. So, I would suggest you prefer the Evie Ring over Whoop 4.0 to save yourself from recurring subscription prices.
While I find Evie Ring tracking good, it can be better in showing data on its app. For example, it can add past data and trends. The Whoop Band provides more details and graphic representation. Sometimes, I get overwhelmed by it.
So, if you are looking for a detail-oriented tracker, Whoop is a good option. Otherwise, the Evie Ring tracks and provides enough information in a simpler explanation.
Frequently Asked Questions
Wrap Up
My overall experience with the Evie Ring and Whoop 4.0 fitness tracker was good, but I like wearing the ring more throughout the day. Given the prices, the band is really expensive. I am getting almost similar data on the Evie app.
Though I appreciate Whoop 4.0 features like physical strain data, recovery data, stress score, etc., which are much more elaborate in its app, my Evie Ring tracks all the major metrics that are essential for my well-being. Plus, the Evie app’s colorful theme is a treat to the eyes!
I am not comfortable wearing the Whoop 4.0 band on my wrist for long periods of time, and if I wear it on other body parts, I have to fit it on my technical apparel. Doing this on a daily basis is too exhausting for me. So, now I am wearing only my Evie Ring most of the time.
