Good Scale
this scale is awesome. It’s accurate. Gives you your heart rate measurement which is really good with a single step on the scale. You can see your weight and all sorts of biometrics about your body.The cool thing is that it also connects to your phone, which can then log your data in the Health app which you can view over time as a trend chart so it’s really good.The app is very easy to use. The screen is very easy to use. It comes with batteries so you don’t need to buy any external batteries. This product is really good and I recommend it for anyone who’s looking for one.

Impressed by my first smart scale.
Great scale. Very accurate. I like the way it looks. Connecting to the app and the scale was very easy on android. The app is called “Starfit” on the google app store. App shows a lot of information. It’s important to stay on the scale to give it time to get all the vitals.

The wellness game changer
I’ve used a number of bathroom scales over the years, but this Smart Scale has genuinely impressed me—it stands out in all the right ways.First off, setup was a breeze. It took less than five minutes to connect the scale to my iPhone, and the Starfit app synced instantly without any hassle. The app is clean, intuitive, and even syncs with Apple Health, which is a big plus for me. I also appreciate that it supports multiple user profiles, so both my wife and I can track our data separately and accurately.The scale itself looks sleek and modern, with a minimalistic design that fits seamlessly into any bathroom. What really caught my attention is the large 3.5″ TFT color display—it’s bright, vibrant, and incredibly easy to read. No more squinting at tiny, dull LCD numbers in the morning! Even better, it displays key metrics like weight, BMI, body fat, heart rate, and more right after stepping on. This means I don’t always have to open the app just to see my stats.What truly sets this scale apart is the depth of data it provides. It goes far beyond basic weight measurements. You get 22 different body composition metrics—including body fat percentage, muscle mass, bone mass, water percentage, BMI, heart rate, and even protein intake recommendations. This gives me a much more complete picture of my overall health and fitness progress.Accuracy is another strong point. I compared the readings with my old scale and gym equipment, and the results were consistently spot-on. Plus, I love that it automatically tracks trends over time, which keeps me motivated and informed.Bonus points for being FSA/HSA eligible, and its compact size makes it easy to carry in a gym bag if needed. You no longer need to pay extra at a gym for body composition scans—this scale brings that level of insight into your own home.Overall, it’s an excellent value for the price—accurate, user-friendly, stylish, and packed with features. If you’re serious about tracking your health or fitness goals, this smart scale is absolutely worth it.

You need this!
I really love this scale. I have two of them, in separate locations. So when I’m not at home I can still track my progress. It’s amazing that the app allows you to connect both scales. Great job!!

great scale, meets my needs
Easy setup and use, the app tracks the various measurements well. The batteries in my scale were dead on arrival, but I knew they were temporary batteries so I put in fresh batteries

Exceptional Smart Scale!
I’m thoroughly impressed with this Smart Scale! The color display is vibrant and easy to read, and the high-precision measurements provide accurate readings every time. I love that it tracks not only my weight but also my fat percentage, BMI, heart rate, etc. The ability to sync with my fitness app is seamless, allowing me to monitor my progress and stay motivated. The scale’s sleek design and compact size make it a stylish addition to my bathroom. Overall, I’m extremely satisfied with this smart scale and highly recommend it to anyone looking to take their health and wellness journey to the next level!

Great customer service
READ UPDATE BELOW TOO! Great customer service! —- I’ve had mine since December and it worked great for about 8 months. Now it won’t measure any of the metrics promised. I’ve done all the recommended things (wet and dry feet, restart it, check battery, reposition feet) and nothing is working. A bit frustrated that I’ll have to buy (a different brand) in less than a year.UPDATE!!!: They reached out to me and are replacing my scale free of charge. Excellent Customer service!!

Impressive Smart Scale with Accurate Metrics and Easy App Sync!
I’ve been using the Runstar Smart Scale for a few days now, and I’m seriously impressed! It’s more than just a weight scale—it gives detailed insights into your body composition like body fat %, BMI, muscle mass, and even heart rate. The 3.5″ color display is bright, easy to read, and adds a nice modern touch to my bathroom.Setup was a breeze. It synced seamlessly with the companion fitness app, and I love how I can track my trends over time. It connects to my phone via Bluetooth and uploads the data automatically—no need to manually enter anything. I’ve compared its readings to those from a professional scale at my gym, and they’re surprisingly close.I also appreciate that it’s FSA/HSA eligible, which helped me cover the cost. The scale feels sturdy, responsive, and updates instantly when I step on it. If you’re someone who’s serious about health tracking or starting a fitness journey, this scale is a great investment.

It’s nice to finally have an accurate digital scale. Much easier to track my weight. And with the extra functions of showing body fat, and all the other options included with this scale software it’s kind of fun.

Item description is falseMentioning 22 body metrics on the listing but on the box it measures only 15. They already have a different model with 15 metrics that is way cheaper
