Incredibly useful for tracking periods, as it adjusts to changes. I wish we could turn off, or skip parts of, the bot chat stuff. Its programming/information is too general and ultimately restrictive. I also would like more symptom options, even just an add your own that you can select again as needed. Thanks for the app!

I used to use this app constantly, but it's become more and more pushy about getting premium. It's obnoxious. 2025 Edit: I can acknowledge that the symptom tracker is good, so added one more star. I had to come back to this app bc the competition is even worse. But the constant annoying popups are still there and I hate them. I will never be getting premium solely bc of this marketing. Now that I can afford it, if Flo was like it USED to be, I'd have a subscription. But at this point, NO.

Hi Kiera! Thank you for sharing this. We’re sorry to hear you’re disappointed that we moved some features out of the free plan. Premium subscriptions fund the ongoing development of the app, while keeping the basics free for everyone. We welcome your feedback. Please email us at support@flo.health. Kind Regards, Flo Team

Some of the couples quizzes and information are kinda nice but as a period tracker couple sharing app it's terrible. She puts all her information in in detail and I get practically none of that information on my side even though that was our intention. There is no setting to change it either, it's locked away. I would understand if it was a privacy thing for some couples but it should be an option in her settings not locked away for everyone.
