Some disorders more or less require tracking to make them diagnosable and their symptoms managable (e.g. PMDD). Managing tracking with paper is ofc possible, but apps allow for reminders and gamification that help on challenging days.

Sure, I'm not saying categorically don't just that people especially in the US and other countries that are having backslides on reproductive rights should think really hard about using period tracking apps if they don't have a strong reason to like you mentioned and even in those cases consider a more deniable and private option.

I agree. It seems pretty apocalyptic :(
