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!

VoiceOver support for all supported languages.

* Calculations based on a gestation of 40 weeks (280 days); adjustable to 41 weeks (287 days) for use in France.

Best app I have used in a long time!

Beautiful interface, simple and easy to use (only one page with three date wheels), and displays information quickly. No bugs I personally found. One possible improvement is highlighting the date when it’s today’s date so that it’s easier to tell when today’s date is selected. Thank you for making this app!

Developer Response ,

Thank you for suggesting we highlight the gestational age date when it’s set to today. It was a little tricky to get right but I think we have something good in the latest 1.2.1 update. Check it out and let us know what you think!
