The Wheel '77 for Android

11 things about The Wheel '77

1. Simply line up the LMP (Last Menstrual Period) pointer on the inner wheel to the month and day of the LMP on the outer wheel, and then rotate the entire wheel so you can see the EDC (Estimated Date of Confinement, EDC is what they used to call the due date before the PC Police changed it to EDD because "confinement" had negative connotations for sensitive modern-day women).

2. If you already know the EDC, you can use the EDC pointer on the inner wheel instead, and then rotate the entire wheel to view any particular month and day during the pregnancy, and then view the week of pregnancy for that date (and take your best shot at guessing how many days).

3. Just like any classic wheel, The Wheel '77 displays all kinds of *approximate* information like due dates, dates of last menstrual periods, weeks of gestation, lunar months, ovulation, quickening, and terms of pregnancy.

4. iPhone users, especially healthcare providers, who would like to be more precise about dates and gestational ages, in a format that is easy to read, might be interested in The OB Wheel Pro 7.

5. The Wheel '77 recreates a classic obstetric gestational age (GA) calculator used by healthcare providers for decades.

6. This app actually replicates a wheel handed out by the makers of Bendectin in 1977 long before lawyers shut down the use of this wonderful drug for nauseated pregnant women.

7. The Wheel '77 is a historic novelty for those clinicians who remember the 70's and those plastic, cardboard and metal obstetric wheels.

8. WARNING: PROLONGED USE OF THE WHEEL RE MAY RESULT IN EYESTRAIN (especially if you are over forty years old).

9. The Wheel RE lets you manipulate the wheel on your iPhone just like you would with wheels of days-gone-by.

10. That modern app is the most complete, powerful, and easiest-to-use tool for healthcare professionals providing prenatal care.

11. A time when just being close was "good enough".
