Oxiline Scale X Pro Review: Your At-Home Version Of A DEXA Scan

It's easy to have a love-hate relationship with scales. Throughout my life, I've tried to put emphasis on how I feel in my body rather than how I look. This means paying less attention to my body weight and putting more emphasis on how much weight I can lift in the gym.

But as I've started to lean into data tracking to expand my longevity, I've realized that my contentious relationship with a scale needed to end—which led me to the Oxiline Scale X Pro.

The smart scale doesn't just track your weight. It also delivers a real-time breakdown of your bone mass, muscle rate, water weight, and body fat at every weigh-in. This makes using the scale feel less like being in high school gym class and more like completing an at-home DEXA scan.

Oxiline is a medical device company that creates blood pressure monitors, oximeters, glucometers, TENS units, and smart scales.

I've dealt with my fair share of scales throughout my lifetime, including scales that connect to a smartphone to help track your weight over time.

But the Oxline Scale X Pro was my very first smart scale and the first time I'd seen a scale provide a much deeper look into my body breakdown.

The Oxiline's sheer amount of data is almost overwhelming—and it's hard to imagine the 11-by-11-inch device can calculate that much information. But it all comes down to the ECHO™ Bio-Electrical Impedance Sensor.

Each scale has 12 auto-calibrating sensors that emit a high-frequency sound pulse through your body. It then uses a combination of user data (height, weight, and age) to calculate additional metrics.

Only eight of the device's 16 data points are shared directly on the scale's LED screen, such as bone mass, water weight, muscle weight, and BMI.

Other reviewers complained about issues connecting to the scale, but my iPhone notoriously has spotty Bluetooth and didn't struggle to connect.

Instead, the app was a useful tool for allowing me to track progress over time with a log of all my old data. It also gave me the option to set up daily reminders to weigh myself until it could become a more regular (and less daunting) habit.

During my first reading with the scale, I was almost overwhelmed by the amount of data coming my way—but it was a great reminder that BMI and weight alone are not always the best indicators of health.

Holistic physician Noemi Adame, M.D., previously explained the complication of just using weight to track your health by using the example of resistance training.

When you first start working out, your muscle mass often increases while your body fat decreases. Your body weight might stay the same and cause you to feel discouraged—even though important changes are happening below the surface.

Unfortunately, I've never done a DEXA scan, so I can't tell you how closely these numbers compare to the scale's data collection. However, I did play around with the scale to test out the precision and whether the ECHO sensors were actually legit.

Testing the sensors

The first test I played around with was not fully stepping on the scale. Instead, I just pressed one leg onto the scale until it hit the body weight of an average person (but kept the rest of my body off the scale).

I wanted to have a better understanding of whether sensors were actually going through my body—or just calculating data about my body based on the sex, height, and age data that I shared when making my profile.

Testing the precision

My second test focused on precision. I wanted to see if the scale would give me the same exact weigh-in numbers from different rooms. I first placed my scale in the bathroom and took my numbers; I then moved the scale to my bedroom.

In the past, I've had scales change their reading within minutes (despite no actual changes like stripping off my clothes or eating and drinking).

I was surprised to see the Oxiline scale gave me the exact same data when I tested it minutes apart on different hard floors.

Comparing data points

I also decided to compare the heart rate tracked by the Oxiline scale and my Whoop. I wanted to get an understanding of how similar (or different) these readers would be.

My Whoop is typically worn on my hand, while the scale calculates heart rates through your feet. Since chest readers are known to be the most accurate, I expected to see some discrepancies between these numbers.
