Customer Reviews

Great but have a request.

I chose this app over Clue because it had an Apple Watch app that actually worked, but I don’t think you can log data when your out of range of your phone or don’t have cellular. Anyway, go this app, I actually log my thing now; I’d always forget using my phone. And this app is more polished and has more features in general though Clue’s ring thing was cool... just the way to log data... they didn’t have enough symptom options. However, the one feature I lost when moving to Flo was the fact that it didn’t connect to the Apple Health and that’s the center or all health data, and Flo is just separate. If the developers are getting bored over there could you add that? Thanks, random reviewer.

More options.

Recently my IUD fell out and I have decided to leave it out. When I say this app I was like yeah this could work. What really won me over was the so called ability to sync with my Fitbit HR Charge 2. Upon downloading the app this did not happen. My Bluetooth is on and I have troubleshooted with Fitbit only to find out this is not a compatible app. As well as more "how are you" options. I would also like to see an option for work under the "other" and what you do as a job, as most of us who use this app are going to work 5/7 days a week and the jobs and physical stress will be different. As for myself I need articles on how heavy lifting and the physical stress it causes can affect the chances of conceiving or change my period. If this could happen would definitely rate 5 stars.

Must-Have for all women

I love this app. I use it in Spanish and am amazed at how advanced it is in providing helpful physical & mental health information as well as Sex Ed. Most apps I have in the Spanish language are VERY low-quality compared to their English versions. I wish I had this app as a young teenager but even in my 20s I find it extremely useful and informative. Especially in Spanish, this free app provides information that every woman should have access to in order to better monitor their own reproductive health. I love it for myself, but my big takeaway is how much low-income women and other vulnerable populations would benefit greatly from access to this information.
