Will Menstrual Apps Save Relationships?

Today's newspaper reports that menstruation apps for men are a booming market. "PMSBuddy", for example, boasts "saving relationships one month at a time". These devices allow men to track menstrual cycles of the woman in their lives. During PMS time a female symbol appears sporting devil horns. If my husband bought such a device I'm afraid his IPod would end up in a garbage can and my "horns" would be extended far beyond the "menstrual cycle".

I read the article in amazement. I thought if men put as much effort into learning to talk to and understand a woman, they would accelerate the process of becoming soul mates. They would also increase the fun and joy that getting to know and accept each other brings. What do you think?
