For women who can’t keep track of monthly cycles on their own as they have done for previously recorded human history, there is the “Leaf” from Bellabeat: http://venturebeat.com/2015/05/27/bellabeat-debuts-its-smart-necklace-that-monitors-womens-monthly-cycles/.  The company states that the app will do things like remind women to get more sleep and facilitate stress reduction.  They state that, “The future of prenatal care” is in bringing “self-tracking tools to pregnancy…to give pregnant women the attention they need and deserve.”
