Bests & Worsts Reviews from Amazon

If you're looking for a scale that accurately measures your weight and logs it, this could be a great choice. However, there are several cheaper options that will also do that for you. I know other reviews have questioned the accuracy. I've found so long as I stand still and balanced, I get consistent numbers that match another scale I trust. Leaning over an edge or moving makes it inaccurate. Even with my size 14 feet that hang over the edges, I'm able to get consistent weight measurements. The big problem with this scale are all the other measurements. First, there's the marketing number of "measurements" which really don't add up. Many of the "measurements", are just the same thing reported in a different way. Giving both a number and a percentage isn't a separate measurement, it's just a different representation of the same thing. I find it dishonest boosting the number over competitors by just simply reporting the same thing twice. Then there's the question of what they're actually measuring, and what is simply calculated. Best as I can tell, most everything is calculated based on your entered age and height along with the measured weight. There is no other way to measure BMI. It's a formula. From there, there's a BMI method to calculate body fat percentage. The percentage that the scale reports for me matches that formula. It does not take in to account body composition in any way. From that number, it calculates the other numbers like lean body mass %, lean body lbs and body fat lbs. There's even a formula to calculate BMR (metabolism) from Lean Body Mass (which is just calculated based on weight - body fat from BMI) which comes very close to what the scale reports to me. I have no idea where they get the Visceral Fat value from. Mine has always been exactly 12.0, never changing despite losing weight. It's magical that it never deviates by at least .1. For Body Fat %, the US Navy method with tape measurements puts me at 13.9 (I work out 15 hours a week, lost 4 waist inches and have my abs becoming visible, so I trust I'm closer to that value than the scale's). This scale has me at 24.1. The BMI method used based on averages just is no where close and badly skews all the other values it reports. Perhaps adding an "athlete" mode would give better figures, but they'd still be all calculated. I have no idea what the electric current actually does. My water weight doesn't change meaningfully when I know I'm dehydrated versus well hydrated. My Protein % remains low despite being on a fairly high protein diet. Now the app. It needs work too. It sometimes creates entries for 10+ years ago which breaks the sync with Google Fit. i have to go to the history and delete those entries to make syncing work again. The Trends graphs are near useless. They need to show a greater scale. Weight can fluctuate by a few pounds during a given day. Weight loss/gain is generally in the 1-3 pounds a week range if you're actively trying to gain/lose. Any meaningful trend needs to be longer term than the past 7 days to remove the noise of daily variance that can actually be more than an actual weekly trend. The charts really need to allow changing the scale to Months with the ability to scale it from a minimum of 3 out to at least 12 to remove natural daily deviations and see the actual trend. The presentation of data is also funky. If Body Fat % + Muscle Mass % + Bone Mass % always add up to 100%, how can they all be "high"? At most, 2 can be high and the third would have to be low or possibly average. Since the numbers are not accurate anyhow, this really doesn't matter. But it still bugs me. If you have an average build, the BMI based estimations are probably close for you. But how many people that are just average and not working to change their bodies really need to know and track all these values? The use case for looking at the trends is people trying to lose weight and/or gain muscle and become healthier. Once you've made some progress, the numbers all become useless. This might lead some people to lose motivation if they don't understand that the scale doesn't actually report measurements.
