I’ve been using this 8-electrode digital bathroom scale every day for a few weeks now, and it’s become part of my morning routine. It’s quick to step on, and the display shows key stats instantly. I like how it tracks not just weight but body fat, BMI, and muscle mass, giving a clearer picture of progress. The readings feel consistent when used properly, though I treat advanced metrics as estimates. The app sync is smooth and helpful for trends. Overall, it’s a reliable and motivating tool for staying accountable and monitoring daily health changes

I love this smart scale. It has 28 essential body compressions data. It's so easy to set up. You can use it for multiple people and my daughter and I love it. She's trying to stay healthier by eating healthier and watching her weight. It shows you the different areas that you need to work on. It tracks your water muscle bones Mass another things to help you keep on track to bring the best healthier version of yourself while you're working out to keep yourself healthy. I love that I can print this out so I can bring it to my doctor office. I love the appearance of this and it shows you your body. I find it very reliable for my daughter and I to measure our body parts. And it's so very easy to read. This was a great value for my money. I would definitely recommend this run star smart scale.

I have been trying to eat healthier, lose weight, and get stronger and this has been an amazing tool for me! It’s so easy to set up in the app and it takes very little time to scan your body and deliver accurate results. You can use it for multiple people on your family. It’s light weight and easy to store. Great value for what you pay. I love that I can see a snapshot of my results on the screen of the scale before seeing more in depth results in the app. Syncing to other apps such as Apple Health is also a bonus.

I got the Run Star Smart Scale and the Fit Index Smart Scale - both of them in the 8 electrode models with the handle bars, as an upgrade to my previous 4 electrode Fit Index Smart Scale. I had them both arrive by the day I was getting a DEXA scan so that I could compare their accuracy. Here are my key takeaways: - Nothing replicates a DEXA scan at home, which I already suspected, but I do think smart scales have a place for tracking trends in-between less frequent DEXA scans. - There is a huge difference between a 4 electrode model and an 8 electrode model. My numbers changed SUBSTANTIALLY when upgrading from 4 to 8 electrodes, within the same brand. The new 8 electrode scale compared to my old data with the 4 electrode version and it was so different, the scale verified I was even the same person!!! Multiple categories’ classifications were changed (as in- good/bad status changed) with the new info. So really, if you want a smart scale, I think there’s no point to get one if it’s not an 8 electrode one. 😳 - The numbers between the two new (8 electrode) scales were close-ish to each other, but both were a little bit further from the DEXA number than I’d like. For example, in most categories the 2 scales were within 1-2 points/percent of each other, but were 6-7 points/percent off of the correct DEXA number. This was the case with Body Fat Percentage (6% off), Body Fat Mass (7% off), and lean muscle mass (9lbs off if I’m comparing the right numbers). - I couldn’t verify everything because some categories (like visceral fat) they use an entirely different ranking system that doesn’t compare to DEXA. Other categories (like water, muscle rate/percentage, bone mass) were not included on DEXA or I was unable to locate them. DEXA also didn’t give me a protein level, but bloodwork from a couple months ago indicated it was “good”, and so did both scales. Again the rankings used were different and didn’t compare, because the scales said 11.7 & 12.4% but bloodwork said 7.1. (not a percentage). But as both put me in “normal” range I figure it’s still in the close-ish category. - DEXA reports are way more annoying to try to decipher and figure out what they mean. The reports given from both scales are way more user-friendly. That said, I found the Run Star scale to be slightly more user-friendly. Its advantages included marking “bad” rankings in red (not just yellow/orange), making them easier to spot and obviously “bad.” Also the body images themselves are color-coded by limb/area, making it quick to see what’s “good” or “bad” instead of having a gray body image and having subtle color-coded word explanations to the side. - The biggest advantage I found to the Run Star scale was that they had better, more thorough explanations for each category than the Fit Index did. Where Fit Index may give a one-sentence explanation of what something is, the Run Star would tell you more about it, as well as giving a lengthier explanation of what to do to improve this number if yours is bad. I appreciate that! - Overall, Fit Index is a much less expensive scale, and most of its numbers/readings are pretty comparable to Run Star, but it doesn’t give you the extra info about each score or how to improve it, and it’s color coding is just a bit more subtle. I prefer the red to stand out as bad so I don’t have to hunt for it between similar intensity colors, none of which really stand out. So really the things I don’t like about Fit Index could be fixed with an app update, should the company choose to do so. Fit Index, if you’re reading this, if you update your app, send me a scale & I’ll update this review! 😉 - The main thing that stood out between the two scales as being significantly wrong is the fact that their Subcutaneous fat numbers were so far apart. Most ratings were very close to each other, but this category had an 8% difference! I wish I was able to know which one was more accurate, since that would have been my deciding factor. Unfortunately the DEXA scan I got didn’t give me that number so I don’t know the winner/loser in that category. Most other categories were within 1 point/percent of each other, though neither was right on target, so I considered the scales comparable to each other but not a replacement for DEXA. The only other categories that were further than 1 point/percent apart between the two scales were basal metabolic rate, metabolic age (2 points/years difference, so still pretty close), and waist-to-hip ratio (.18 off, which is a lot when the numbers are 1 or less!) - Since I don’t know which one was right/wrong on the subcutaneous fat score (the only notably different score between the 2 scales), I chose which scale to keep based on my preference for Run Star scale’s app. I preferred its readability and color coding and appreciated their lengthier explanations of each rating. It’s a bummer because my old data is saved in the Fit Index scale app already, but I just really like having the extra info there. So I’m keeping the pricier one of the two. But if you want to save money I think Fit Index is a comparable scale at a lower price point. I just don’t know which one was so far off on the one ranking of subcutaneous fat.

received my scale yesterday. I was excited to try it out and see what kind of data it would provide. Right out of the box, it was fully charged. The Starfit app was very simple to set up and get dialed in with my info and goals. The Scale itself is stout and well-built, with no loose parts, making it a nice and solid scale. Turning it on and watching it come to life was a simple process. I put my phone next to the table, opened the app, as the instructions state. You step on the scale with bare feet, ensuring your feet cover the metal pads on the scale. You hold the handle part as instructed, making sure your thumbs are on their metal pads and all four fingers are on their metal pads. You step on the scale with one foot to activate it. When it shows 0.00 in the window, it is ready for you to step on. Hold your arms in the correct position. The scale will take your weight very fast, then about 4-5 seconds after, your phone will start to play some music (you can turn this off), the handheld screen will show a person's body with the energy waves going through the arms, legs, and body. Maybe 15 seconds and then the music stops, you can relax your arms and watch the screen, it will show you a bunch of data over the next 10 seconds if you want to watch it. If not the app will have an amazing report for your to view, More data then you can imagine. Honestly, some real solid information all well presented and logical order. Some of it was like a Blood test, with your numbers and the range of normal numbers as well as a graph of where you are on the scale. The report is very informative and can be printed on a single page of paper as well as tracked in the unit. Yea, I am inpressed and excited to see how my body changes, not just my cloths fitting better but no muscle loss or minimual muscle loss and plenty of body fat lost. best purchase so far. I will update in 30 days and then again at 60 days.

I’ve gained a lot of weight the past 6 months. I blame the holidays. I want to get back on the right track so I have begun eating healthier and want to lose the weight. I bought this scale hoping it could add some insight into my body stats. I’ve never had a scale like this. I synced it to the app and put in my body information and from there it keeps track of my weight and other information like my bmi and water weight. I really appreciate the water weight stat because I’m perimenopausal and it puts me at ease when I see the scale change because of water weight.

Before purchasing this type of scale, it’s important to understand what it is—and what it is not. This is not a diagnostic tool. It is not a reliable measure of overall health for all body types. And it should not be used to set personal weight or fat percentage goals without medical or clinical oversight. For individuals with a history of body dysmorphia, eating disorders, or obsessive tendencies around weight or appearance, this device could reinforce harmful behaviors. The language used (terms like “obese,” “plump,” or “overweight”) is blunt, potentially misleading, and based on outdated classification models. These may trigger or validate distorted body perceptions, especially for users unfamiliar with how these values are calculated or misapplied. ⸻ What the Scale Does Well This is a consumer-grade bioelectrical impedance analysis (BIA) tool that estimates body composition by measuring the resistance of tissue to a small electrical current. It does a reasonable job at: • Estimating body fat percentage • Breaking down segmental muscle mass (arms, legs, trunk) • Reporting total body water, visceral fat grade, and protein/muscle mass • Offering trend tracking if used consistently (same time of day, same hydration state) For individuals who are emotionally grounded and experienced in reading their own data, this can be a helpful tracking device over time. ⸻ Where It Falls Short The core issue lies in its reliance on population-based models (like BMI, WHR, and body fat norms) to interpret results. These models are known to misclassify: • Muscular or athletic individuals • People with large frames or dense bone structure • Individuals who have undergone major weight loss but retained high lean mass For example, someone with high muscle mass and low metabolic risk factors may be flagged as “obese” or given a goal weight that is inappropriate for their frame. Scientific literature has long criticized BMI and similar tools for overestimating obesity in high-muscle individuals and underestimating risk in lean-appearing but metabolically unhealthy ones. ⸻ Bottom Line This scale can be a helpful tool for trend tracking, especially when used with clinical support or by informed users. But it should not be used to define health, appearance, or self-worth. For vulnerable users, the risk of misinterpretation is real and significant. Health is multifactorial. No single number—or app screen—tells the full story.
