The Wheel SP is now the most powerful and easiest-to-use gestational age calculator in the App Store!
The Wheel SP (for ‘SPinner’) is a gestational age calculator (also known as a pregnancy wheel) that is used every day by doctors, obstetricians, midwives, nurses, and pregnant women. The Wheel SP is a professional tool that replaces and enhances the functionality of those worn-out cardboard wheels without compromise.
The Wheel SP 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), or from the date of conception, or from a known gestational age (GA) on a known date, e.g. from an ultrasound measurement, or from fetal biometry like Crown-Rump Length (CRL), Femur Length (FL), and Biparietal Diameter (BPD). Additionally, for appropriate gestational ages, The Wheel SP estimates fetal weight and display the number of days completed and remaining.
However, in its primary day-to-day role for healthcare providers, when the EDD is already known, The Wheel SP enables the precise calculation of the gestational age of a fetus at anytime during pregnancy in LARGE, easy-to-read characters.
To enter Gestational Age, CRL, FL, or BPD for a specific date, tap “Today”, enter the desired date, then repeatedly tap on the newly-displayed button displaying the gestational age to cycle through GA, CRL, FL and BPD.
To see information about the current gestational age (e.g. fetal weight, days completed/remaining) tap the gestational age display when NOT highlighted in white.
