Cholesterol checker advice.

Options
Just got a cholesterol checker and need advice on the following.
What is a good app for logging measurements?
Why doesn't this app do that?
What do the measurements mean?
What are good and bad measurements?
Thank you kindly for your patience and help.
If you also want to ask the community anything I've missed here, please do.
BTW my Cholesterol is 3.3 mmol/L, whatever that means. Does that make me a Pepperami?
