"If you do have a specific body goal — whether it’s to lose weight or get jacked — the Aura app will also contextualize where you’re at and how to get there. I set my goal as an “athletic” body with muscle gain. The app, in turn, told me I’m about 80 percent of the way there already and recommended I increase my caloric intake by 10–15 percent, add more protein to my diet, and do no more than three workouts per week."

This strap turns the Apple Watch into a comprehensive fitness tracker. It was so easy to add to the watch, and it's even easier to put on your wrist. If you have diet or exercise goals, this is the product you need for your Apple Watch.
interesting and accurate measurements every time. the results have been giving me information that's very useful to me, no silly fluff, just the important things compiled for my exercise record
I try to work out every day, and I really like to know if I'm improving.
Now with this device, it has given me data to maintain lasting results.
With this I can know my muscle weight, percentage of lean mass, percentage of fat, proteins and especially “water”.
All this in a simple and practical way.
The app keeps me informed and I can improve each of these items.
For me it has helped a lot, it has been very important to know if I am gaining or losing mass and fat.
This has helped to build a better body and especially to realize the need to improv
I have some health issue and am on my way to a healthier living. This keeps track of some vital information daily and gives me overall view of my health. This is very helpful for what my daily regiment should be. Immediately the information was helpful, and I will adjust my habits. This unit is exactly as the vendor describes.
This watch band is really simple to use. I have an Apple Watch 8, 45 and the band fit straight out of the box. There are several different bands that are included so you can get one custom for your specific model.
You pull the protecting tab to the battery, attach the watch band l, download the app and you’re ready to go.
I had to enter in my age, height and weight.
It seems accurate as far as body fat composition, but I don’t have anything to go on as far as the
protein, minerals or water levels.
I’m hoping that’s accurate as well.
The band is comfortable, but I will not be using it for every day use.
I plan on changing out the bands when I do my measurements.
If this works correctly, I think it’s a very neat device. It has a guest mode so if you wanna let someone else analyze, it’ll do so without saving over top of your records, which I thought was a nice feature.
That’s a really nice watch strap 🙌
Now I can forget about my scales with BMI technology. Strap 2 shows same numbers but doesn’t take a place.
Would recommend. Easy to use and intuitive interface, sleek design, and great battery life. For the price this is a great value.
I typically don't use fitness trackers but i'm trying to achieve specific goals to get into better shape. I read a review on this AURA Strap 2 and decided to give it a try. it is super sleek and very easy to attach to my Apple Watch. The features are really cool and i can now track things like fat, protein levels, water levels (this is an important one for me) and a lot more.
Let's see how i progress with my workout routine now that i have all of this data.
Nice looking band. 😁
If you go to the gym 3 times a week, then you will enjoy this thing.
