QuixCalc

QuixCalc is a free set of 60+ online calculators and everyday tools, built to give you a quick, clean answer without the clutter. It spans finance (compound interest, margins, fees), health and fitness (BMI, TDEE, calories), home improvement (concrete, paint, mulch, tile), payroll, dates and times, and developer utilities like a JSON formatter, UUID and password generators. Every tool runs entirely in your browser, so there is no sign-up, no download, and your inputs stay on your device. It is free to use and made to be genuinely helpful for the small calculations people run every day.
