Pregnancy Wheel

Pregnancy wheel application is created to replace the traditional pregnancy wheel or obstetric wheel (OB wheel) with a modern user interface. There is no year entry/selection for gestational age and due date (estimated delivery date - EDD) calculation, year determination is handled by the application. Therefore, date entry becomes faster. Application has several other features that can be used to create a date timeline and calculate dates from template for indicated gestational weeks, calculate estimated fetal length and estimated fetal weight for respective gestational age. There are several other calculations which include milestones, baby fruit/veg size, zodiac for EDD, and gestational terms.

Application starts with the last menstrual period module. Additional modules can be accessed using the navigation menu. In each module besides the due date (estimated delivery date - EDD) and current gestational age, milestones, baby fruit/veg size, zodiac for EDD, gestational terms, predetermined pregnancy weeks and timelines are calculated. Gestational weeks’ and timelines’ templates can be edited in the settings.

Languages supported include English, Spanish, Turkish, German, French, Italian, Portuguese.

With other applications like mail or Whats App, the current screen can be shared as a picture through the share icon. Calculations are updated when the parameters changed and done pressed but some people may prefer to use the reset icon to initialize the screen.
