Easy to Use with Detailed Health Insights

I was a bit skeptical about how accurate the Aura Strap 2 would be, but I’m blown away! The body composition measurements have been spot on compared to other fitness tools. I love that it syncs with my Apple Watch, so I don’t have to juggle multiple devices. The design is sleek and comfortable too. It's definitely a great addition for anyone who wants deeper insights into their health without complicated setups.

Impressed

I'm very familiar with my body and have used other digital devices to calculate these measurements. To have this all in one is amazing, I'm impressed with the accuracy, the advantages for keeping this data tracked so effortlessly and to have it available at the touch of my hand is something. Thank you for the invention.

Fantastic for Apple Watch Users

If you already use an Apple Watch, the Aura Strap 2 is a perfect companion. It extends the functionality of the watch, offering metrics that other wearables don’t provide, like body fat percentage and muscle mass. It helps me tailor my workouts and nutrition to be more effective. Setup was easy, and the device feels sturdy and comfortable during my workouts. Great product!

Amazing Health Insights, Slight Learning Curve

The Aura Strap 2 is a game-changer in terms of providing in-depth body metrics like fat percentage and muscle mass. It’s definitely helped me stay on top of my fitness goals! My only issue is that there’s a bit of a learning curve with the app and syncing the data. Once I got the hang of it, though, it’s been smooth sailing. I’d recommend it to anyone looking for more comprehensive health data, but be prepared to spend a little time getting used to it.

Really insightful

I love this app and my Aura 2 loops! It's really helping me to build the body I want because I have insights into how my workouts are affecting my weight, muscle mass, fat, water, BMI, etc. the app is super easy to navigate as well. I would recommend it to anyone who really wants to take control of their health.

Such great app!

Love the app because it has easy interface, but I get plenty of info about my body composition. This app exports all the data to Apple Health, and it is giving me full picture of my body's physical performance. It's easy to set it up and start monitoring your progress, whether it's losing weight or building muscle (which is my case). I found it especially useful, since I train regularly. And this app give all info about my body's changes. That's really great!

Love the Aura Strap

I’ve had mine for just about a month … easy to set up and the monitoring feedback is fabulous. Tracks more than my body comp scale! Whatever you’re looking to improve, weight, building muscle, nutrition… this strap monitors all and the app works fantastic!

Accurate and Motivating Health Tracking

I’ve tried several fitness trackers, but the Aura Strap 2 stands out with its accuracy and the detailed insights it provides. It's incredibly motivating to have my body composition and hydration levels tracked throughout the day, and it’s easy to see the data on the Apple Watch. The measurements help me make better decisions about my training and nutrition, and the app interface is clean and intuitive. It's a solid investment for anyone who wants to take their fitness to the next level!

Stellar service meets high tech fitness

Aura Strap, a sophisticated fitness companion, shines with exceptional customer service and game-changing features. This product isn't a traditional plug-and-play, requiring a learning curve to unlock its full potential but it is 100% WORTH IT.
The customer service is second-to-none: attentive...

Easy to use and informative

My AURA Strap 2 is such an upgrade from my body comp scale. It gives me the data and insights that I need to help me stay on top of my goals and it’s incredibly easy to use. Love the integration with my activity that provides a deeper overall view of my metrics.
