The Aura Strap 2 is redefining wearable fitness by turning your Apple Watch into a personal body composition tracker. Unlike traditional smart scales, which require you to step on a platform, the Aura Strap 2 provides real-time readings right on your wrist, making it easier than ever to stay on top of your fitness goals. With measurements for hydration, fat percentage, muscle mass, and other metrics, this sleek accessory is gaining attention among athletes, biohackers, and anyone serious about monitoring their health.

Key Features of the Aura Strap 2
The Aura Strap 2 goes beyond standard fitness tracking, offering results similar to high-quality smart scales, such as the Garmin Index S2. This level of insight, combined with the on-the-go convenience of wrist-worn technology, makes it an appealing tool for fitness enthusiasts and dieters alike. For those interested in extra features, the Aura Plus subscription offers extended insights and personalized fitness plans. However, the device itself is fully functional without it, and buyers receive a complimentary six-month Aura Plus trial.
Aura Strap 2 Colors and Design Upgrades
The Aura Strap 2 comes in several colors, making it easy to match with any style or Apple Watch band. Building on the original Aura Strap’s success, the Strap 2 is significantly improved. It boasts a 20% thinner design, a faster Bluetooth-enabled connection for near-instant readings, and new, precise sensors that capture 20 times more data points than its predecessor. Aura claims these advancements provide nearly clinical-grade accuracy, which is impressive for a compact wearable.
Another notable update is the material switch, as the strap now features a comfortable silicone loop instead of the previous velcro-style band. With multiple sizes included in the box, getting a snug fit is easy, ensuring optimal readings from the stainless steel electrodes.
How to Set Up and Use the Aura Strap 2
Setting up the Aura Strap 2 is a breeze. Simply download the companion app, set your fitness goals, and you’re ready to take measurements. Adjusting the strap size may take a few extra minutes, as you’ll need a tool to access the battery compartment. Once it’s set, though, the app guides you through each reading.
To get the most accurate results, keep your hands apart and ensure the electrodes make contact with the fleshy part of your palms during the 20-second measurement process. The Bioelectrical Impedance Analysis (BIA) sends a low-level electrical impulse through your body, analyzing hydration, fat, and muscle composition data in seconds. For beginners, the app offers helpful, real-time guidance to make the learning process smooth and easy.
Accuracy and Comparison to Other Devices
The Aura Strap 2 is said to have 95% accuracy compared to DEXA scans, which are considered the gold standard for body composition analysis. In practice, its readings closely align with smart scales like the Garmin Index S2 and the Tanita RD953. However, because Aura measures from wrist to wrist, while many scales measure from foot to foot, there may be minor differences in hydration and fat percentage readings. Still, the Aura Strap 2 is consistent enough to identify trends, making it ideal for those tracking progress over time.
The Aura Strap 2 App
The companion app is where the Aura Strap 2 truly shines. Along with tracking hydration, fat, and muscle composition, Aura Plus subscribers unlock detailed fitness guidance, personalized workout recommendations, and a “Biogram” feature, which visualizes body composition trends over time. For users who enjoy analyzing data, the Biogram is especially useful, as it plots progress in easy-to-read quadrants, helping users see how close they are to their fitness targets and how they compare to others.
Ideal for Athletes and Long-Term Tracking
While the Aura Strap 2 doesn’t offer real-time hydration alerts during intense workouts, it provides reliable insights into your body’s composition over time. For athletes, it’s a valuable tool to monitor hydration, fat percentage, and muscle mass, making it easy to assess progress or adjust diets and workouts based on consistent trends.
