## Description

Preg Wheel is a fast, free pregnancy wheel app for iPhone that eliminates the need for a paper wheel. It lets you quickly input key dates—Last menstrual period (LMP), estimated date of delivery (EDD), estimated gestational age (EGA), and IVF dates—with accurate results that account for leap years and calendar variance.

It also saves your inputs for later, streamlining your workflow, and presents important prenatal screening dates such as first-trimester US, CVS, Quad Screen, Amino, Anatomy US, GTT, Anti-D Prophylaxis, GBS Screen, and Elective Delivery.
