I know there are quite a few of us here, who access MH through our phones (or iTouch). I just found out that they finally released their O Tracker App.

MedHelp has recently launched their first iPhone app called My Cycles! The My Cycles app helps women track their periods and ovulation and predict future periods and fertile windows. It's great for women who want to keep track of their monthly visits from Aunt Flo, schedule vacation plans around predicted period days, and track their basal body temperature and other signs of ovulation because they're trying to conceive.
You can download it for free here:

I can't wait to try this!
