Also would be cool if it could act both as a factor and a symptom so you could see correlations of this data both being as something affecting you and also something being affected by something. I have a blood measurement tool like a glucomètre but which can measure more things and I’d like to track them here as well because they play important role in health. Especially for those who are on kept diets, who are anemic, who has joints problems etc, it can be very useful.
