Colours on food bars?
I've got a bunch of questions about the food log and I can't seem to understand this... I'm going crazy so I really hope one of you can help me! I'm fairly new to Samsung Health and the new update.. I've tried googling but can't find any answers.
Firstly, when I open the overview of how many calories I've eaten the last week I don't understand why one bar is green and why the other one is blue? Are there any more colour? What do they mean and which colour should I aim for?
Secondly, when I look at the calories I've eaten during a specific day there are also different colour and grey patters on the horizontal bars. What does green, blue, stripes and plain gray mean?? I also thought the bull's eye was the calories eaten in total, but it's different? I'm so confused!
Pleeease help :')
