Wondermeter is a small museum of instruments that measure delightful, useless, wonderful things about you: the seconds of your life ticking live, the chemistry between two names, the books still ahead of you, your record lap on a keyboard stopwatch.
None of it is important. All of it is true (or honestly labelled as a game when it isn’t). That combination — real arithmetic in service of pure wonder — is the whole idea.
Three promises
- Everything runs in your browser. There is no server doing calculations, no database, no account. Your birthday, your name, your score — none of it is sent anywhere or stored by us.
- Free forever. The site is plain static files supported by a handful of unobtrusive ads. No paywalls, no subscriptions, no “premium” results.
- Every instrument earns its place. Each tool is a genuinely different idea with its method explained in full on the page. If a tool can’t be made honest and delightful, it doesn’t get hung on the wall.
How results are shared
When you share a result, the link itself carries the inputs you chose — encoded in the address, readable by no one but the page. Whoever opens it sees your reconstructed result and a completely blank form to make their own. We never pre-fill anyone’s data into anyone else’s screen.
Colophon
Hand-built static HTML, CSS and vanilla JavaScript. Type is set in Gloock, Public Sans and IBM Plex Mono — open-source faces, self-hosted. No frameworks, no trackers of our own, nothing to slow the page between you and your number.
