Clear blue ovulation

Clar

Me and my husband decided to try for a baby next month so I decided to track my ovulation. On the app I ovulate Friday but today I decided to try the ovulation stick to see how accurate the app is. I got a solid smiley face and it has stayed that way. Does this mean I am at peak fertility? Can someone explain these test? And the best time to start trying. We want a boy so I heard it’s best to do it the day you ovulate.
