Apple can really be frustrating - as any large corporation.
I could really find it useful to log weight, activity and sleep data. I use Autosleep with my Apple watch and weight from my Withings weight.
Not sure if they support ifft, shortcuts or the likes - but it may be useful if Diarium could import arbitrary data from such services. Would make it possible to consolidate loads of information.
Anyway - Thanks for a fantastic product even without health integration :-). Bought it for Mac OS, Ios and Windows.
