Best pregnancy app?

Elizabeth

My wife just found out she's pregnant. We are over the moon since it's our first baby ever. I would like to know what kind of <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">pregnancy app</a> do you use. We haven't announced due to her bicornual uterus. We would like to wait til 3 months in. Thank you!
