Movano Evie Ring Review: Is It the Best Smart Ring for Women?

Evie Ring Review


In a world full of health trackers worn on wrists and fingers, Movano’s Evie Ring is the first of its kind—a smart ring specifically designed to cater to women’s needs. It’s a new product that offers many promises, but is it up to the task? Let’s find out in this Evie Ring Review!

The Evie Ring, from Movano Health, was created to fill a gap left by health trackers available in the market. Aside from monitoring basic vital stats such as heart rate, blood oxygen saturation (Sp02), and so on, it is also meant to keep track of women’s menstrual cycles, as well as mood and energy levels.

Before we proceed into the specifics, let’s take a quick look at the Evie Ring’s characteristics and specs.

Evie Ring Review: Specs and Features

First, the Evie Ring is made using a proprietary material its makers call “LiquidMetal.” This is basically a zirconium-based alloy coated with titanium PVD coating for a shiny finish. It measures 8mm wide and 3mm thick and weighs 3.2 to 3.7 grams, depending on the size you choose. It’s available in sizes 5 through 12 and comes in Gold, Rose Gold, and Silver finishes.

The Evie Ring has a unique design—it has an opening on one side of the ring to accommodate daily changes on the wearer’s finger. It’s worth noting that the opening itself has a distinct look, with one end a square and the other end angled like a triangle. The gap created by this opening is very helpful in keeping your finger free in certain situations, such as when you feel bloated in the morning. With the Evie Ring’s gap, you won’t have to resort to using things like soap to remove your smart ring painlessly.

Next, the Evie Ring has several sensors that are used to monitor vitals. These include:

  • Optical heart rate sensors (red and green LED)
  • Infrared heart rate sensors
  • Skin temperature sensor
  • Photodiodes
  • An accelerometer

All of these sensors are meant to monitor the user’s heart rate, resting heart rate (RHR), heart rate variability (HRV), skin temperature variation, respiration rate, and SpO2 levels. The team behind the Evie Ring claims that it also tracks period and sleep and monitors steps taken, active minutes, distance traveled, and calories burned. Let’s talk about these later.


The Evie Ring is water resistant to one meter deep, which means users should avoid using it while swimming or beside deep water. Its battery can be charged from 0 to 100% in just 90 minutes and can last for up to 4 days on a single charge. The device comes with a charging case that contains 10+ charges, meaning you can take it with you anywhere without worrying about the battery running out.

The device works with a well-designed companion app for the iPhone. It is not compatible with Android devices at the moment. It costs $269 with no monthly subscription fees, making it more affordable than other more popular brands such as Oura and Ultrahuman.


What the Evie Ring Is Best Used For

With all of its features, you can use the Evie Ring for the following purposes:

Personalized Health Monitoring

The Evie Ring accounts for differences in vitals between men and women and does its best to measure RHR, HRV, and SpO2 accurately. For instance, healthy women tend to have slightly higher RHR compared to men (78-82 vs. 70-72 beats per minute (BPM)). By getting the right measurements, you will be able to get a better picture of your overall health condition.

The Evie Ring measures your vitals in different ways. It passively measures every five minutes whether you’re awake or asleep, gives you real-time measurement on the spot for a period of 40 seconds, and also keeps track of vitals while you work out.


Workout and Fitness Tracking

Speaking of working out, you can also use Evie to keep track of your heart rate and HRV while breaking a sweat. These biometrics will give you insights as to whether you can keep going, or if you need to take a break and prioritize recovery. The device can also tell you if you’re under stress so that you can take it easy. However, the device won’t track your workouts automatically. You will need to log in when you are about to start exercising.

Aside from monitoring vitals as you exercise, Evie will also monitor the number of steps you take each day using its built-in accelerometer. It will combine this with your heart rate to tell you how many calories you have burned and give you detailed insights about your overall fitness levels.

Sleep Tracking

If you’re looking for a smart ring to help you improve your sleep patterns, the Evie Ring is a good choice. In addition to tracking biometrics, it will also monitor your sleep patterns, sleeping respiration rate, and the duration of every sleep stage you go through. These data, combined with your biometrics, allow the Evie Ring to determine how your sleep affects your overall health. The Evie app will then provide you with recommendations on how you can improve your sleep.

What’s best about this is that the Evie Ring does this while your fingers remain comfortable, thanks to the ring’s design.


Menstrual Period Logging

A woman’s menstrual period brings hormonal changes that can affect many things, including sleep quality and overall health. By using your Evie Ring to log and keep track of your menstrual cycle and PMS symptoms, you can get recommendations on how to manage your well-being.

Over time, Evie will use the first date of your last period and cycle length to provide an estimate of your next period, fertility window, and ovulation date, presented in a calendar format. It will also help you identify patterns and gain insight into how your period affects your overall health.

Mood and Energy Monitoring

Evie can also help you understand how your mood and energy levels are affected by your biometrics so that you can manage it better. To do this, you must log your mood and energy levels daily as if you’re writing in a journal. Evie will then use the information over time to help you spot patterns regarding the changes in your mood.

Evie Ring Pros and Cons

Just like any other smart ring on the market, the Evie Ring has advantages and disadvantages. You need to consider these before deciding to purchase it—or at least be informed of the following if you’ve already paid for it.


  • Looks really good as a smart ring. Some may not even notice that it’s a health tracker because of its appearance.
  • Gap provides a lot of comfort whether you’re bloating or not, awake or asleep.
  • Can be used by men, but it has special features designed specifically for women.
  • Able to track patterns better the longer you log more information on it. This means it can provide better recommendations over time.
  • App interface is friendlier compared to those from competing smart rings.
  • Long battery life, with the ability to charge on the go.
  • More affordable compared to other smart rings available today.
  • No monthly subscription fees.


  • As a first-gen smart ring, it still has some issues that need a lot of ironing out.
  • It looks good, but it tends to get scratched very easily. You need to avoid doing things that can affect its aesthetics.
  • Sleep tracking measurements can be inaccurate at times.
  • Ability to count steps taken can be inaccurate at times as well, especially when compared to other devices like the Apple Watch.
  • Does not automatically track exercises. If you forget to log your exercises, it won’t store any relevant data.
  • Menstrual tracking feature has room for improvement.
  • Water resistance is limited to a depth of 1 meter.


The Verdict: Is The Evie Ring the Best Women’s Health Tracker?

So, is the Evie Ring worth buying? For us, it’s both a yes and no—yes if you’re a woman and you don’t mind waiting for Movano to drop some updates to improve Evie, and no if you’re already using another smart ring that does its job properly, and has no need for a specialized device to keep track of your monthly periods.

It’s worth considering that Evie is still very new at this point, which means there could be bugs affecting its overall performance. Since it’s their first smart ring, the team behind Evie is sure to make some improvements down the line so that the device will work properly as intended. It has so much promise, and if its makers eventually succeed in making its features work accurately, women everywhere will have a powerful health tracker worn on their fingers, not their wrists.

That said, if you’re already using another smart ring from another company, such as Oura, and are merely considering switching to Evie because of its women-focused features, we suggest waiting for updates to fix the current errors plaguing the device before buying it. You can use other apps to log your periods while you wait for Evie’s menstrual period logging features to improve.
