It's really a shame that you can't log emergency contraception, since it has a huge effect on many women's cycles. Changed my review to 1 star as the above issue still exists, and have since discovered several upsetting features, for example, constantly being reminded I might be pregnant before my period is due. This app was made by men, I'm convinced. Unsubscribed.

Hi Flo! I’ve been using this app since high school, and now in college, I can say it’s a great tool. The community is amazing for connecting with other girls, and the assistant is super helpful during all phases of the cycle. For someone with a healthy, regular period like mine, it works really well. However, my sisters, who have irregular periods, have experienced bugs—like the app not loading properly or only showing how late their period is. If these issues get fixed, it would be a big help.

I've been using Flo for at least a year now, and it's been good, design wise it's clean, easy to navigate, but I'm feeling fatigued with all the questions in text message style, and I don't like how it assumes partnering and having children is the default. It isn't for me, they should be optional. I've decided to switch to an app founded by women to align more with my values of supporting women (rather than men) when it comes to women's health. To the developer: half the world is women -1 star.
