Yeah, as I said before in another comment I would be surprised "if the people that designed the Fitbit's period tracking feature did not include or at least consulted women".

I take your comment (and the tweet I linked) as being correct about my assumption.

As a non-American (I am European) I am always amazed about how easily things like that are attributed to gender (non) inclusion in the USA. On the other hand, as a male I have to always wonder if I find these kind of reactions over the top not because I am not American but because of my gender.
