As many of the other commenters are saying it is a sequence of numbers where the next number is given by the sum of the previous two numbers starting with 0, 1 (then; 0 + 1 = 1, then 1 + 1 = 2, then 1 + 2 = 3, then 2 + 3 = 5 ...)

You see the number chain occur naturally many places in nature in the development of seeds or leaves in plants, where the number of seeds or leaves in layers occur as fibonacci sequences, e.g. one layer has 3 leaves, the next has 5, next has 8 so on.

On a funny side note, you can also use it to approximate conversion of miles and kilometers, as 2 miles is approximately 3 km, 3 miles is approximately 5 km

I use a Libre2 chip that has a plastic sensor going through my skin into the underlying tissue to measure the blood sugar, but it is not accurate compared to a blood sample from the finger plus there is a delay when you measure the bloodsugar in the muscle tissue compared to the finger, so I highly doubt someting sitting on the outside of the skin on the wrist can do it even closely precise, but I have a small hope - exciting technology at least. If it works just slightly reliable it is a complete game changer for all people with T1D or T2D.
