I really welcome the Health Kit or Google Fit approach for sharing data among health app, I actually want to use that for health research. The main problem is that as soon as you mention the fact that patients data is going to be shared with a company (besides in the US) doctors shy away because of data protection, regulations etc. We need the data to be on the device and possibly outside of the control of one (or 2) companies. I know Apple says that data is encrypted end to end, and I wish Google did the same, but even so it is still problematic. When you add the fact that every manufacturers of wearables obliges users to share data on their dodgy platforms... I don't see a solution to this. At least not until the mindset changed completely.
