About

OneTask is a collection of small web tools that each do exactly one thing. A percentage calculator that answers the question you actually asked. A word counter that loads instantly. A QR code generator that hands you a PNG without an account.

How it works

Each page is a static HTML file with the tool's logic in a few kilobytes of JavaScript. There is no framework, no bundler and no client-side router. The calculation happens on your machine, so the tools work at the speed of typing and keep working if the network drops.

Why it is built this way

Most tools of this kind are heavier than the job they do — a sign-up wall in front of a division, or two megabytes of framework to count words. Doing the work in the browser removes the round trip, removes the privacy question, and removes the reason to ask who you are.

Who builds it

OneTask is built and maintained by Tim King, founder of REGRAVITY. Tim writes the specification, the explainer and the test cases for every tool, and each calculator is checked against the published source named under its explainer before it goes live. Corrections sent to the address below are fixed and the page's updated date moves with them.

OneTask is a project by REGRAVITY, and appears in its case studies.
