I would love love love to see an <a href="https://play.google.com/store/apps/details?id=com.glow.android">ovulation tracker</a> on the calendar! I've used apps in the past that would let you know when you were fertile, but those apps didn't feature the great stuff <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> does. I have had to track my periods on two apps so I can know exactly when I am ovulating. Please consider offering this in the next update!!!!!
