Prego Wheel

Quick and easy to use obstetrical date calculator designed and developed by a family physician.

I'm a family physician regularly seeing obstetrical patients. I needed a streamlined, no frills, quick and easy to use obstetrical date calculator for use in the office. While there are many apps already available, this one provides exactly the information I need on one screen. Hope you enjoy it as much as I do!

Émilie Coudière, M.D., family physician and creator of Prego Wheel

Quickly calculate:

  • Estimated date of delivery (EDD) from last menstrual period (LMP)
  • EDD from gestational age (GA) on ultrasound
  • Patient's GA as of today
  • Date of future GA — i.e. When will my patient be 28 weeks?
  • GA on future date — i.e. How many weeks will my patient be on June 15th?

That's it. One screen. Super simple!
