Wife's Hostility Meter

Wife's Hostility Meter is a joke that we use with our girlfriends.

Wife's Hostility Meter produce three values based in biorhythm which are displayed on the screen. We created a meter that changes color depending of the value of Hostility. The Hostility is combination of biorhythm values, what we called The Castelló Theorem, created by Paris and his extensive research with his wife.

We also added a Ogino calendar-based method indicator for sex. It suggest when is good time for intimacy.
Wife's Hostility Meter is not intended to be a contraceptive app or a real method of predicting somebody's behavior.

The main idea came from Jonathan that was complaining one day about predicting the behavior of his wife, so we put everything together and created the application.

By Paris Castelló, David Chumpitaz, Jonathan Haddad and Jose Rivas.
