24 free calculators for health, finance & school

OUNZOZ is a free platform of 24 fast, accurate calculators for health (BMI, calories, macros, body fat), finance (loans, mortgages, savings, currency), and school (GPA, statistics, quadratic equations, fractions). Every calculator runs in your browser — no signup, no data stored. Formulas are sourced from official standards (WHO, clinical references) and clearly cited. Built for people who want a fast, accurate answer without ads or clutter.
the cited formulas from WHO and clinical references is honestly what sold me on it, you know most calculators just throw numbers at you with zero sourcing
@jesseeisenberg Really glad that came through! It was actually one of the harder
decisions early on — every calculator's formula had to trace back to a
real, verifiable source before it shipped. Good to know it's the thing
people notice first.
Love that the formulas cite their sources like WHO and clinical references — gives actual trust to the numbers instead of just hoping they're right.
@rseybek97138 Thank you! That was intentional from day one — a calculator without a
sourced formula is just guessing with extra steps. Appreciate you
calling it out specifically.
