NOTE: A fix has been submitted to fix the crash on startup with iOS4.

The Wheel is a gestational age calculator (also known as a pregnancy wheel) used every day by doctors, obstetricians, midwives, nurses, and pregnant women. The Wheel is the most elegant and functional replacement for those worn cardboard calculators ever developed on ANY computing device.

The Wheel easily and accurately determines the estimated delivery date (EDD), or due date, of a pregnancy based on the first day of a woman's last menstrual period (LMP).

The Wheel also effortlessly calculates an EDD based on a known gestational age (GA) on a known date, e.g. from an ultrasound measurement performed at any time during pregnancy.

However, in its primary day-to-day role for healthcare providers who take care of scores of pregnant women, when the EDD is already known, The Wheel simplifies the precise calculation of the gestational age of a fetus anytime during pregnancy in LARGE, easy-to-read characters.

AND, The Wheel is the ONLY gestational age calculator that lets you know about the full moon(s) for each month!

The Wheel is also internationalized for Spanish, German, Italian, and French versions.
