We'd always love to have more types of data, but we haven't yet prototyped anything that uses additional sensors. At the start we really thought that reliable heartrate and bloodpressure sensing watches would be on the market very soon, and we kinda designed the early versions with that in mind. As the product developed, we were surprised how much useful status information and trend analysis could be done with just activity and location data.

The long term trend analysis of this kind of data interests us a lot, in the simple case of activity levels, most seniors go through a very gradual decline, and there's no point at which anyone recognises the need for intervention and a change in exercise habits. I think if people had the analysis more readily, they'd see this and it could have quite a positive outcome by prompting people to make changes in habit to recover their former activity levels. The same analysis should work equally for chronic conditions, and if you can merge information about medication then you should be able to recover a very complete picture.
