Apexa Pro
Free calculators for finance, health, cooking, kids & more
Free online calculators for percentages, age, loans, BMI & calories, concrete, Airbnb ROI and AI token costs. 100% in your browser — fast, private, no sign-up.
Hey Product Hunt! 👋
I built Apexa Pro because I kept bouncing between a dozen different
calculator sites, each cluttered with ads, forced sign-ups, or missing
exactly the one tool I needed.
It's now 128 free calculators — no sign-up, no downloads — spanning
finance (mortgages, loans, compound interest), health, cooking,
automotive, sports, and even a whole section of animated learning
tools for kids (base-ten blocks, an interactive number line, a
fraction pizza — built to make math actually fun to look at).
A few I'm personally proud of if you want a fun first stop:
→ Coffee composition calculator (see coffee/water/milk ratios
poured in real time)
→ Live salary counter (watch your earnings tick up in real time)
→ Interplanetary trip calculator (find out how long it'd take
to reach Mars at the speed of light... or walking)
Everything's bilingual (English/Spanish) and runs 100% in your
browser.
Would love to know: what's a calculator you've always wished existed
but could never find? I'm actively building and this is genuinely
useful feedback for what to build next. 🙏
Love that everything runs entirely in the browser with no sign-up. The tabbed layout keeps all those random calculators I actually use (loan, BMI, concrete) one click away without any clutter.
How does the Airbnb ROI calculator handle things like occupancy fluctuations or seasonal pricing, or is it just a flat-rate estimate?
