Health
Excellent device ! Recommend it as I know it as of May 28, 2016.
If I find ERRORS in reporting on weight as is often the case with so many apps. that report my weight as :
160. O
When my actual weight is
91. 0
I wonder how accurate 3 app. are that Apple offers for Health.
Report the known problem to the vendor ~ send the particular corporation / business - that created your app. to address your problem.
Hopefully they can correct it. I do not know if the correction is permanent YET.
Hope this message helps.
