Hi Product Hunt! 👋
I built Calmatro because I wanted one simple place for the everyday calculations and conversions people normally have to search for across many different websites.
Calmatro currently includes 200 free calculators, converters, and utility tools covering finance, math, health, dates, units, travel, business, education, technology, and more.
One of my main goals was making the tools accessible internationally, so Calmatro is available in 8 languages. Everything can be used without creating an account.
This is an early version, and I’d really appreciate feedback from the Product Hunt community. Which calculators or converters would you like to see improved or added next?
