The people behind MedCalc

Design

MedCalc is developed by Pascal Pfiffner and Mathias Tschopp, two Medical Doctors who believe you shouldn't be able to recognize medical software by their lousy user interface.

Localization

The following people have contributed to our localization efforts:

  • French: Mathias Tschopp
  • German: Pascal Pfiffner
  • Portuguese: Jairon Carvalho Moura
  • Simplified Chinese: Hongyang NI
  • Spanish: Rodolfo Marín, Ariel Joel Hdez Viveros, Antonio Martin Marco, Juan Pablo Piombo, Iñaki Martinez de Ilarduya Muñoz, Eliseo Rodriguez Claus, José María Pérez Ramos

We have built a friendly web-based localization tool that requires no technical knowledge. Don't hesitate to contact us if you want to help localize MedCalc in your language.
