Is it ok?


I’m a high school student who discovered this app through a friend. A few of my other friends although think it’s wrong and silly of me to keep track of my period.

I highly disagree, I would rather have a track on my period or at least a good prediction so I know and don’t get my period and not be prepared.

But now I’m having my doubts because of their comments.

Is it ok? Or are they right?
