The developer

Built by a real person.

Jean Borg

Founder & developer · freecalculators.pro · Malta

I build and maintain every calculator on this site myself, from my desk in Malta. No faceless company and no outsourced content – each tool is coded by hand, shows the exact formula it uses, and gets fixed the moment something’s off. Need a calculator that isn’t here yet? Email me and it’s usually live within the hour, free.
