Software and Hardware
The hardware I purchased was the Blueweigh Smart Body Composition Analyzer Scale (about $70.00 from the big A). The scale alone only shows body weight. To find the other components measured this software is required. My scale is very nice looking white glassy thing with a peel off label that says, Slippery when wet! It really is slippery when wet.
There may be other hardware units that work with this software.
Software: Obviously, you have to tell the software about you. You have one very important thing to input. That is whether you are sedentary, or if you exercise moderately or professionally. The choice made appears to have very significant results in the analysis of what the scale's data result in the software report.
The combination of software and hardware is supposed to provide analysis of: body weight, body water, body fat, muscle mass, visceral fat, Bone Density, BMI, and BMR. So does the combination work to provide what otherwise would require things like an MRI, DEXA scan, body submersion and multiple caliper measurements??
Remember the choice of sedentary, moderate or professional exercise?
Here is what I found.
Muscle mass: either 118 or 131 lbs. Pounds are not mass.
Bone density: either inadequate or adequate depending on the exercise level.
Body weight: either chubby or skinny
Other parameters: similar variations depending upon the choice of three exercise parameters.
What's wrong here is that my muscle mass when I step on the scale is what it is. My bone density is what it is and is not dependent on how many times I exercise per week. But to me, it appears that the choice of exercise level is a uniquely important and significantly misleading parameter in this hardware and software combination.
I am reminded of an old acronym: GIGO. Garbage in, garbage out.
Is the scale accurate? I put known weights on it and after several weighings the results were correct. As for the other measures, who knows if they are accurate?
The most important defect is the internal inconsistencies.
The software only allows tracking of one person. There doesn't seem to be a graphing capability or method of exporting data to spreadsheet or database.
The hardware is pretty and shiny. And, beware, "Slippery when Wet!" Very much so.
The software is cute in an "English my pretty and wholesome talk for your benefiting way" if you like that.
By comparison, consider an older Om*** model. Allows four people, tracks 90 days high and lows and doesn't care about your exercise level but can deliver varying results depending upon how long you have been laying horizontal or if your hands have been at sides for a prolonged period (a three hour long walk drastically lowers the Om*** assessment of body fat percentage.)
