One more thing..., again
Thanks for adding the ability to calculate by a known gestational age. I also like its ability to see when a woman will be a certain gestational age in order to plan procedures & delivery. I personally like this version more than the spinner; the calendar view is great when somebody can only remember her period started on the last sunday of the month or if she knows she conceived a certain weekend...
Drawback - Sometimes, its a bit confusing. Once an EDD has been set and you go looking for a gestational age on a particular date, its hard to know that you havent accidentally screwed up the EDD - which can lead to a major error. Id like to see a small message, i.e. "based on EDD of Oct 15, 08" below the calendar and above the EGA. Even better would be to add the gestational age in small print on each day of the calendar, once an EDD has been determined.
As for as it being $14.99, this is pretty steep for an OB wheel. I think its worth it for practicing obstetricians, but it may not be worth it to students, residents, nurses, and other doctors who dont do a high volume of OB. Id bet at $9.99 or less, youd make up the decreased price with volume.
