The accuracy will improve over time, but the real challenge for all of these health tools is that they accomplish a job most people aren't trying to do.
A lot of people say they care about or would be curious to follow things like their weight, BP, or heart rate, but very few people actually do. The barriers aren't even very high--taking your morning, resting heart rate or stepping on a scale is dead easy, it's just not very valuable information to most of us.
Heck, what most people who have hypertension, pre-diabetes, or obesity really want is for the disease to just go away. Since a quick pill or surgery for many of these problems don't exist, not thinking about the condition is the next best thing.
These health tools are getting a ton of press lately and I have no doubt that they'll be very useful for doctors and the committed few, but the real problem to be solved is motivating people to care about their health like they care about their bank accounts.
