No wearable can see what you ate, how much you drank, or whether you woke up
feeling ill. Those things shape your physiology more than most of what a watch
measures, and the only way in is you typing them.
It is one of the five things we need to learn
We want to know which of these people actually use.
Our guess is that two or three get used constantly and the rest almost never. If
that is right, the finished app should put those two or three within one tap and
stop pretending the others matter equally.
The only way to find out is to give you twelve options and watch which survive
contact with real life.
This means not logging is also an answer. If you never once record a bowel
movement, that tells us something. Do not force yourself through markers you
interest in — you would be teaching us the wrong lesson.
It makes several numbers personal
Some figures change character entirely once you log:

How to log well
Honestly. What is true, when you remember.
Incompletely. One meal recorded and two forgotten is real data.
Without going back to tidy up. Reconstructing a week from memory produces
tidy fiction. A gap is a real answer — see Please do not
perform.
Whenever you remember. Everything can be backdated, so logging last night’s
dinner this morning is fine.
What is on offer
Twelve markers: weight, body fat, blood pressure, blood glucose, ketones,
Lumen, nutrition, hydration, alcohol, bowel movement, period, sickness.
Plus Night Log for night wakings, which
works differently.
Use the ones that interest you. Ignore the rest.
