About Tools Bucket
What we build
Tools Bucket is a collection of small, focused tools for everyday tasks — working out your exact age, checking your BMI, converting units, estimating a loan payment, generating a strong password or a QR code, and more. Each tool does one job, loads quickly and works on any device.
Your data stays with you
Every tool runs entirely in your browser. The dates, measurements, amounts, passwords and text you enter are processed on your own device and are never uploaded to our servers or stored.
How the tools work
Calculations use standard, published formulas — the WHO adult BMI categories, the fixed-rate amortization formula for loans, exact international unit definitions — and each tool page explains the method it uses. Results are for general information and are not medical, financial or professional advice.
Always free
All tools are free with no sign-up. Browse the full list of tools to find what you need.
