I love all these new noninvasive QS gadgets, but for me the problem will always remain that to find meaningful/useful correlations, you always need to input a lot of data manually (in your example:"I just drank a coffee".)
Until that's solved, and I don't see how it could be, they will remain mostly useless toys to me (who am utterly lacking the discipline to enter data reliably enough for statistical analysis).
I just started logging my coffee by putting an NFC chip by the coffee sources. I press my phone to it, select type and volume. I was shocked at how easy it was to set up.
