Overall great app, periods are never a surprise and I like that my partner can see when I'm supposed to start. A few things I wiss the app had: 1. I wish I could share certain articles with my partner. 2. Hot flashes or chills should be added to the symptoms list, especially for those headed toward menopause and wish to track symptoms that could mark the beginning of that.

I've been using Flo since 2019 and it's pretty spot on as far as accuracy goes as long as you keep up with your dates/symptoms. I love everything about it, EXCEPT for them constantly trying to shove premium in your face. It's extremely annoying that I can't even open the app without an upgrade popup.

This app used to be great -- simple and easy to use. Now they've "upgraded" it. It bugs you to subscribe every time you open. Pop-ups. Annoying animations and illustrations. User experience now sucks. I use it now because it has my history, but how do you go from an B+ to a D- overnight. Awful. Tell the CTO this sucks.
