Easy to use multi-functional gestational age calculator. Ob Wheel (or obstetrical wheel) will help to compute gestational age as well as estimated due date/estimated date of delivery (EDD) swiftly and intuitively with input such as last menstrual period, ultrasound measurements, In-Vitro Fertilization (IVF) and other methods.
App is created to replace the paper or plastic wheels which have tendency to be inaccurate for several days. Although this application designed for healthcare providers, anyone can use it because of its user-friendly interface. There is no year entry/selection for date input, the year is determined by the app. As a result, entering dates becomes significantly quicker. App can create a date timeline and calculate dates from template. It can calculate estimated fetal length and estimated fetal weight for respective gestational age. Templates for gestational weeks and timelines can be edited in the settings. There are several other computations which include pregnancy terms, milestones, baby fruit/veg size, zodiac for EDD, and gestational terms.
Supported languages include English, Spanish, Turkish, German, French, Italian, Portuguese.
App modules to calculate due date and gestational age:
1) Last menstrual period (LMP)
1) Ultrasound (USG)
2) Crown-rump length (CRL)
3) In-vitro fertilization (IVF)
4) Due date
5) Head circumference (HC)
6) Symphysis fundal height (SFH)
7) Transcerebellar diameter (TCD)
8) Discrepancy calculation: Calculates degree of discrepancy between LMP calculated gestational age and USG/CRL calculated gestational age.
9) Review: Can be used anytime during pregnancy or after delivery for retrospective computations
Other modules include
1) hCG doubling time calculation
2) Institute of Medicine (IOM) pregnancy weight gain comparison according to body mass index (BMI)
3) Bishop scoring
Application works offline and ad-free with rewards! When rewarded ads are watched banner ads disabled for 7 and can be topped up by 7 days. Banner advertisements are present in the application interface at the top of the window. Easily copy calculation results to clipboard by tapping on them. Moreover screen can also be shared as image file without the ads.
