The kit
If you came here from the book, this is the right page. Both printables are below — no email, no form, no waiting. The formulas sheet is generated from the same verified data the calculators use, so it can never drift out of step with the site.
The Numbers Log card
One printable page for your quarterly re-check — the instrument from the book.
Formulas cheat sheet
Every formula on this site, with its citation, on one printable page.
The Numbers Log, on screen
The same card, live: enter your figures once a quarter and it keeps the history, shows the change since last time, and prints back to the same layout as the paper version. It stores everything in this browser only — there is no account and nothing is uploaded.
Everything you type here is computed in your browser. Nothing you enter is stored on a server, sent anywhere, or shared — there is no account and no health data to leak.
No ads on this page, by design.
Want the quarterly reminder?
The whole point of the log is re-taking it. Four times a year we will nudge you, and tell you if any reference value behind these tools changed. Entirely optional — the downloads above need nothing from you.
Double opt-in: you will get one confirmation email and nothing else until you click it.
