The method calculators
The method calculators — 2 tools, each showing the formula it uses, the source that published it, and the date that source was last checked.
My Numbers Log
The Numbers Log keeps eight to ten body metrics on one card and asks you to re-take them four times a year, so you are reading a trend rather than a single figure. Everything stays in this browser: there is no account, nothing is uploaded, and you can export or delete it all whenever you like.
PopularWhich numbers matter
This sorts body metrics into screen, track and act using the checking intervals that named bodies such as the USPSTF, the ADA and NICE actually publish, plus whatever you say you are already working on. It orders a list for you; it does not assess your health or recommend anything.
