I wouldn't worry too much about those comments. Personally, I'm a little offended that they think they know who the app is obviously targeted at. It' s extremely sexist on their part to assume who "obviously" has a use for this app .

As RevdKathy pointed out, she was well aware of her cycle (as were most of the women I know/knew when this topic came up).

I thought it'd be nice to use so I know whether my wife is likely to be in the mood or bite my head off. Crud now I made a bad joke. Anyway, tracking that doesn't come naturally to me, so I thought this app(bad joke and all) migh be useful to me, a (gasp) man.
