Full calculatory.app homepage — the Fast, Lite, accurate masthead followed by the Financial, Education, Health & Lifestyle and Everyday tool grids.
Most calculators are cluttered, ad-choked, or wrong. People doing everyday math deserve a tool that just works.

Problem

A loan, a BMI, a grade — simple math, buried under ads and sign-up walls. No brief asked for this to exist. It should exist anyway.

Solution

Built as a free public utility on a utility-first philosophy: speed, simplicity, accessibility. Four categories — each with carefully curated, accurate calculators — built on Astro and Tailwind.

  • Finance

  • Education

  • Health & Lifestyle

  • Everyday

Outcome

  • Free to use. Always — no ads, no sign-up.
  • Built for the person who just needs the answer, not another product to manage
  • Design treated as a civic act — giving back through tools that work
