The best period tracker app. This app is awesome, you don't get unnecessary contents, there's a separate page for topics that you want to know or discuss about. It's so easy to use.
Very useful app. Predictions are accurate too. Provides good guidance and education on female reproductive health. Helped me track my periods until I got pregnant. Very good app.
Best menstrual cycle tracker. Plus I upgraded to premium and the features are great. More like an all around health app. Nutrition plans, sleep courses, daily health care advice from doctors for women.
I. AM. SHOOK.I have been using this app for years now and with every update it just gets better. The Forecast notifications are CRAZY accurate. Today it said I could expect acne and when I touched my face I found a tiny zit! It is crazy awesome. I love this app.
It’s one of the best apps I have ever had! I have irregular periods so whenever I go to the doctor I can actually show them the length of my cycle and show them any symptoms I have. I love flo!
This app literally saved my life! Without it I would have known I had PCOS! Thanks to the tracking it was able to pick up on some things and I was able to share the information with my gynecologist! Thanks Flo 😊
This app gives you insights about your period and cycle, but more than that, it gives you insights into how you might feel. Or why you feel the way you to. It may sound silly but I didn’t realize how much of my mood and behavior is determined by my cycle. It feels validating and has given me a new connection to my body.
I have been using this app for over two years now and it is the most reliable and most used app on my phone. It helps me keep track of my cycle, and lets me log my mood and activities. I have the premium account and I find the articles and Flo Health Assistant to be very helpful. If I could give this app 6 out of 5 stars, I would. If you are a female, you should have this app :)
So helpful! Worth the subscription! I’ve always had really irregular periods and a ton of complications & this app is GREAT for helping keep track of everything. With the subscription you can also get detailed reports of everything that you enter in to show your doctors. It has been so incredibly helpful in a medical sense! 10/10 would absolutely recommend to anyone.
