Medical and Health Calculators/Apps

A guide for medical and health calculators chiefly for UToledo clinicians and medical students with an additional section for all (chiefly patients).



This guide provides  information and links on medical and health calculators relevant to the UToledo community. While it is primarily for clinicians and health sciences students, additional resources are included for all.

Includes general resources, finding guides, and key resources for UToledo clinical specialties and UToledo medical students. It is not meant to be comprehensive.

Are Medical Apps regulated?

The FDA is taking a tailored, risk-based approach that focuses on the small subset of mobile apps that meet the regulatory definition of “device” and that:

  • are intended to be used as an accessory to a regulated medical device, or
  • transform a mobile platform into a regulated medical device. 

Mobile apps span a wide range of health functions. While many mobile apps carry minimal risk, those that can pose a greater risk to patients will require FDA review. Please visit the mobile medical apps example page for a list of examples of mobile medical apps that have been cleared or approved by the FDA. Visit the Mobile medical apps that the FDA will regulate webpage for a more detailed list of examples of mobile apps that would require FDA review.

For many mobile apps that meet the regulatory definition of a “device” but pose minimal risk to patients and consumers, the FDA will exercise enforcement discretions and will not expect manufacturers to submit premarket review applications or to register and list their apps with the FDA.
