Lean body mass incorrect
It looks like sonar is reading body mass from Apple in kg but not converting to percentage.
Ie 80kg lean body mass in Apple is reading as 80% in Sonar without taking into account overall weight. So 80kg lean mass on 120kg person is 66.66% not 80%.

Lean body mass showing as percentage. It is retreaving data from Apple in kg but showing as % incorrectly. Ie 60kg LBM on total weight of 120kg = 50% but showing as 80%. I’m guessing the similar user comparisons may be incorrect also. Thanks. Tried connecting Withings LBM but won’t show any data.

I suggest that the comparisons would also be incorrect.

Can you have another look at this please. It still shows incorrect percentage.

Update with the fix should be available early net week.

a fix has been made and will be submitted shortly to Apple for review. We've moved forward with "kg" instead of percentages. The reason for this is because not all users have body weight measurements available

David Fazzalari: Thanks for that! Would you expect to see the value as it's shown in Apple Health (i.e. kilograms) or as a percent?

Byron I think % would make more sense, being a universal measure.

Thanks for flagging this. Just took a look, and I see that Apple Health displays lean body mass in terms of body weight rather than a percentage.
We'll look into updating that on our end as well.
