Weirdly Useful started with a single question nobody could answer at a dinner table: how many times has my heart actually beaten? Ten tools later, the idea is unchanged. Ordinary habits become fascinating the moment somebody bothers to count them.
How the numbers are made
Every tool uses well-established population averages — resting heart rate, blink frequency, orbital periods, calorie counts — applied consistently so comparisons stay meaningful. Each page includes a "How it works" section that shows the exact arithmetic, and every input is adjustable so you can replace our averages with your own.
Privacy by design
There is no backend, no database and no account. All calculations run in your browser, and nothing you type is transmitted or stored anywhere.
