3.4 Unmet Needs & Market Gaps

• Poor Reading Consistency: Some users complain about inconsistent results from multiple measurements, or readings drifting with slight position changes, undermining trust in product accuracy.
  

  Stepping on and off several times will get you different readings so there is some inconsistency. // Customers have mixed experiences with the scale's accuracy, with some reporting inconsistent readings and only being able to monitor one person's weight.

• Poor Smart Scale App Experience: Companion apps for smart scales have underdeveloped features, un-intuitive chart displays, and even connection issues, affecting the continuity of data tracking and analysis.
  

  The app is ok. You can't manually add a weight. Also the charts are not great. If you look at the year, it does not give you all the months, it just gives you one dot to represent 2025. If you look at the month it will give you two months and no ability to change the dates to change what you are looking at. // Sometimes you have to step off and back on again because for some reason the app doesn't catch the weight.

• Short Battery Life or Inconvenient Battery Type: Users report fast battery drain requiring frequent replacements, or the use of uncommon battery types like CR2032, increasing usage cost and hassle.
  

  Customers have mixed experiences with the scale's battery life: while some appreciate that it comes with two AAA batteries included, others report that the batteries die after a month and the scale goes through them quickly. // The battery life seems like it'll drain pretty quickly because the automatic shut down takes way to long compared to others I had in the passed.

• Questionable Accuracy of Body Fat/Body Composition Data: Body fat, muscle mass, and other data promoted by some smart scales significantly differ from users' actual physical conditions or measurements from professional equipment, leading to skepticism about their scientific validity.
  

  However, the fat/muscle/tissue measurements are bs. It is so off. During the last 6 months I have gone from 25-30% body fat to about 12%. The scale says 21-22%, it has been saying the same % since I bought it even though I made a total body transformation in the meantime.

• Insufficient Weighing Platform Size: For users with larger feet or heavier weight, existing platforms feel too small, causing instability or inability to place feet fully, affecting comfort and safety.
  

  It's small and if you are a bigger person or have big feet, it's not ideal. // I have size 13 (US) feet and have to position my feet carefully on the scale so that my heel and toes are fully on (I have about a spare 1/4" front and rear). If you have feet larger than size 14 (US) you might have to have your toes extend over the front of the scale and keep your weight between your heels and the balls of your feet.
