Males using this app...?

I have nothing against guys using this app but isn’t it odd? Isn’t this a female app?

*Edit: Holy shit, I was just asking. I didnt understand. RELAX. Like I said I have nothing against it and dont care I just didnt understand why.

Edit No. 2: I’m using the eve period tracker app. Maybe thats why I thought it was just for females. I didn’t know that a bunch of apps were tied into one.

Thanks for your answers. Maybe some people really need to give other people the benefit of the doubt before attacking other people for asking a damn question.
