HealthKit seems a bit half-baked. I can see it being really useful in the future once everything is "Healthkit enabled™," and data magically flows in, but it certainly has many bugs.
As an example, for a while I was manually entering my weight every couple days. After two weeks or so of doing this, the data simply vanished without a trace. This happened again after one of the early updates. After that, I simply gave up. Yes, a bug report was sent, but who knows what really happens once it goes through the 'Gates of Radar.'
