alt Hacker NewsMost of the women I know well enough to know this about them track and predict the onset of their next period without needing an application. It isn't exactly rocket science.

This is a strawman argument. Nobody is arguing that period apps are a necessity. Women have been tracking our periods without computers since prehistoric times. Women were doing rocket science calculations before computers, for that matter. Of course we can do without period apps. But they're more useful than any other health tracking device or app that I can think of.
Well, until some years ago we remembered dozens of phone numbers, birthdays, routes, physical addresses, due dates, etc.
The trick is to "give a tool for 1-2 generations of customers" , and then they'll be fully dependent on the tool.
