We're using Flo specifically, mostly for sharing stuff like "her period starts tomorrow" to the both of us, she doesn't really need a notification for that :)
I'm not sure I understand your argument. It's important enough that she has it set up to share that data to both of you, but it's so unimportant she doesn't need a notification for it?
Yes, it is useful for me as a partner to know, ideally without having to ask her, and not important for her to be notified, since without the notification she'll notice it anyways sooner or later...
I'm sorry but this is bordering on parody to me. The way she would notice it "sooner or later" is by her bleeding on her clothes and possibly even furniture. In what world is it important for you to just know about it and somehow not important for her to avoid that?
