This app vs other ovulation apps

I'm a complete control freak and was curious if my ovulation schedule on here was the same as other trackers. Well it's not. I really like this app. I love the way it's setup, it's easy and I enjoy features like this, but I'm really concerned if my ovulation day is correct or not, and which app has it right
