I came across this tool which originates in Germany, it just needs values for TSH, FT4 and FT3 and from there tries to characterise underling Thyroid conditions. I've downloaded it fine, and it's fairly simple to set up. Not sure how easy the results are to interpret though.

As it's Open Source it's free to use and seems to come from reputable researchers.
This article puts the tool into context supporting patients on T4 therapy but still reporting low quality of life frontiersin.org/articles/10...
