AURA Strap 2 vs Bioimpedance Scales

AURA Strap 2

Bioimpedance Scale

Title

Ease of use

Easy to use: just place your hand on the device buckle.

It's necessary to step on the scales to check your body composition

Title

Flexibility in use

More flexible: collects data on fitness, activity, and other parameters for more accurate analysis.

Offers basic modes, such as “Normal” and “Athlete,” without considering many additional factors.

Title

Portability

Wearable device: as long as it's on your wrist, it can measure your body composition anywhere.

Used only at home since it’s a static device.

Title

Data analysis and storage

AURA app analyzes and stores health data, and allows you to track your body composition changes throughout the day.

Scale apps are usually limited to result history and offer fewer analysis options.

Title

Integration with Apple HealthKit

Deep integration with Apple HealthKit, storing body composition and other metrics for access through third-party apps.

Usually only syncs weight data with Apple HealthKit.

Title

Updates

AURA app is updated 2-4 times a month with new features and improvements.

Scales are rarely updated and usually do not offer new features after purchase.

Title

Measurement accuracy

Measures body composition through the upper body (arm and chest), which can cause slight differences in data.

Measures body composition through the lower body (legs and pelvis), which may provide different results.

Title

Accuracy based on location

A portable device that can measure body composition anytime, helping track the effectiveness of workouts.

Measurements can only be taken at home, limiting the ability to track changes in real time.

How can body composition tracking help me?

A series of day-by-day measurements shows the trends as your body composition changes. It makes your workouts more efficient, because you can understand (by the numbers) what exercises are definitely good or bad for you.

AURA Strap 2 is water resistant. The device will not be affected by high moisture or immersion in water up to 50cm / 20 inches. But the device may suffer from direct exposure to a high-pressure water stream. We do not recommend diving, water skiing, or other activities involving high-velocity water or submersion below shallow depth.

The electrodes on each side of the device are made using medical stainless steel (contains nickel).

No, we don't recommend using the device with a pacemaker.

Can the AURA Strap 2 detect medical conditions or illnesses?

No, the AURA Strap 2 is not designed to detect or treat any medical conditions or illnesses.

How does Strap 2 connect with Apple Watch? Is it secure?
