About Daily Micro Tools
One free micro-tool, every day. Each tool answers a single question people actually type into a search bar — how much house can I afford, when can I retire, what does a dog really cost — and answers it with a working calculator, not a wall of text.
Who runs this site
Daily Micro Tools is an independent publication. There is no newsroom and no content farm: every tool is designed, built, and checked by a small team before it ships, and every calculator on the site is verified against an independent reference calculation (a second implementation, or published figures from a primary source) before it goes live. If a number on this site is wrong, that is a bug, and we fix it like one.
How the tools are made
Each tool starts from a real question, not a keyword list. The build spec opens with the reader's situation — the salary, the house price, the retirement age — and the calculator is built to answer that situation with transparent math. Every tool page shows its work: the inputs, the formula in plain language, and the assumptions behind the defaults.
Money tools use clearly stated assumptions (for example, tax tools name the tax year and filing status they model), and every finance page carries the same honest footer: figures are estimates for illustration, not financial, tax, or legal advice. When a page cites an external figure — a pet-care cost study, a tax bracket — the source is named on the page.
What this site is not
There are no accounts, no paywalls, no newsletters harvesting email addresses, and no personalized recommendations. The site does not sell anything and does not collect personal information from visitors. Advertising, when served, is how the operation sustains itself — the tools stay free either way.
