3 years ago I am not a medical expert.. how is the calculation differs for adults and children?
The evaluation for the weight, fat and so on depends on the age. If it can't evaluate a measurement for a specific age then openScale will not do an evaluation to avoid false information.

3 years ago I'm not an expert neither, but I guess the calculation differs. I will try to gather some information about that.
Anyway, one main difference between children and adults is that as an adult, the body's height usually doesn't change, but a child's height hopefully will rise. ;-) As a consequence, on the one hand there's no static height, but a constantly growing one. On the other hand, there's no target weight. That is both parameters (height & weight) constantly changes up to an unknown value which they approach asymptotically. If that could be mapped in a first approach, that would be great.

2 years ago Yes that's a fact that kids are growing :wink: Unfortunately, changing the height to a non-static value will, at first glance, change a lot in the implementation but it is possible.

2 years ago I've searched the web a little to find out how to calculate the optimal body index for children, but the only information I found is that there's no formula but a table made out of statistic values, with age, weight and height as the important parameters. Unfortunately, I haven't found the table's values at all.

2 years ago Just saving the data and displaying it would be a great first step in the implementation Of course some adult calculations applied to kids would not make sense and this mat be ignored
openScale is really fine for adults, but I'm using it for tracking my children's body data as well. That purpose in mind, some possibilities are missing.
What I miss most is the possibility of capturing a child's (constantly growing) height together with its weight. There's usually also no targeted weight or height (excepted the expected height calculated out of the parents' height and the child's gender - from which again an expected average weight could be derived). I guess that the formulas for calculating the optional weight, BMI etc. differs from those for adults as well.
Due to the many different requirements for children and adults, I think that it would be an appropriate approach to have a different set of parameters depending on the persons age, i.e. wether it's an adult or a child.
