The Wheel RE (REtro) is for those iPhone users who yearn for the days when everything was (almost) free, and just being close was "good enough".

The Wheel RE recreates the classic obstetric wheel gestational age (GA) calculator used by healthcare providers for decades. This particular replica was scanned from a wheel handed out by the makers of Bendectin long before lawyers shut down the use of this wonderful drug for nauseated pregnant women. Just like the classic wheel, The Wheel RE 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.

The Wheel RE lets you manipulate the wheel on the iPhone just like you can with those obsolete cardboard, metal, and plastic wheels of days-gone-by. 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). 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).

FEATURES:
- Approximate EDC from LMP
- Approximate GA weeks (and days) from LMP or EDD
- Approximate EDD from a known GA and date
- Estimate pregnancy ovulation
- Identify the term of pregnancy
- Retain chosen EDC and date of interest

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 Wheel SP, a full-featured gestational age calculator which uses a "spinner" interface to enter dates and gestational ages. Or, users might be interested in the original The Wheel, a visual, calendar-based gestational age calculator that includes all of the SP features and more. Both of these professional tools are available here in the App Store.

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

Pros and cons of The Wheel RE app for iPhone and iPad

The Wheel RE app good for

As an OB/Gyn this helps in calculating when someone is going to be a certain gestational age. The the SP helps fine tune that dates. Thanks very much.
Great price (free) and elegant concept. Hard to get more info in a glance than with the old-fashioned OB slide rule.
This is cute and brings back memories, but I cant imagine anyone actually using this. BUT, I do intend to show it to all my colleagues as the most expensive pregnancy wheel ever made, and to show them how the more things change, the more they stay the same.

Some bad moments

Theres a free one that does it all in the FREE med calculator
Everyone is familiar with and loves the cardboard OB wheel. This one allows both the outer and inner wheel to spend, and accurate implementation of the real world device. But the graphics are so poor that no one can see the fine markings and actually read it or use a clinically. All that you had to do was implement pinch and zoom and this wouldve worked perfectly. I suspect it has been abandoned by its developer as it hasnt been updated in a long time. Too bad. Great idea. Weak implementation antation.
