iFetal Pro [for iOS]

iFetal is a scientific pregnancy calculator designed by doctors originally for medical professionals, but with some modification, now it is suitable for patients as well. This could be a valuable present to 1st time pregnant couples for a better pregnancy care. iFetal provides more than 45 different calculations including normal fetal measurements, standard dates for screening tests plus weekly pictures with audible heartbeats by just a "tap". You can email, save and track the results. You can learn about medical terms/tests by a simple tap on educational web links in the info page.

Here are some of the information iFetal can calculate for you:
the day the egg was conceived (conception date)
the due date,
the time frame for 1st antenatal appointment
9 recommended antenatal appointments from week 6 to delivery
the earliest date that a home pregnancy test can becomes positive
the earliest date that the fetal heart will start beating
the earliest date to book for a dating ultrasound scan
the standard dates for booking a routine fetal developmental ultrasound scan
the recommended dates for booking 1st and 2nd trimester screening blood tests including combined test (nuchal translucency scan, PAPP-A and beta hCG), multiplexed maternal plasma DNA sequencing test (a new blood test that may eliminate the need for NT scan and amniocentesis), triple, quad or penta screening tests
time frame for amniocentesis and chorionic villus sampling (if required)
iFetal allows you to adjust the number of days in each period (not everyone has 28 day cycles) thus the most accurate calculation of due date and conception date
fetal age can be calculated by: 1) the first day of the last menstrual period (LMP), 2) by conception date (CD) or IVF date, 3) by previous ultrasound scan, and 4) by due date (EDD)
reverse calculation of the LMP, CD by EDD or any other methods
correlated gestational sac diameter with the gestational age in the first trimester
calculation of the 1st day of the 2nd and 3rd trimesters
countdown to the due date
correlation of the EGA with the normal ranges of the human chorionic gonadotropin (hCG) levels in the first trimester
correlation of the EGA with the expected size of the yolk sac diameter (YSD) in the first trimester
correlation of the EGA with the expected size of the gestation sac diameter (GSD) in the first trimester
correlation of the EGA with the normal ranges of the estimated fetal weight (EFW)
correlation of the EGA with the normal ranges of the amniotic fluid index (AFI)
correlation of the EGA with the normal range of fetal length (crown to rump) before 20 weeks
correlation of the EGA with the normal range of fetal length (crown to heel) after 20 weeks
correlation of the EGA with the normal range of fetal heart rate (FHR) for each week of pregnancy
correlation of the EGA with the expected size of fetal head, abdomen, femur length, long bones in the lower leg, humerus length, long bones in the forearm and foot length
weekly developmental changes
pictorial demonstration of fetal development from week 2 to delivery
weekly audio of fetal heart beats
fast forward or backward review of the pictures and audio playback
one tap to email results, save to iPhone/iPad, print wirelessly, or open on your Mac
links to save the dates and appointments directly from the result page to your calendar or by creating new events
User friendly design: one tap on the "Calculate" creates all of the above information

Other Features
Calculation of your age in days, or weeks, or a combination of years, months, weeks and days. When are you going to be 10,000 days old?
Did you know what day of the week you were born or what day you were conceived? iFetal can calculate that for you. Just enter your DOB and tap.
