  • Not working anymore

    By KitsuneMama
    Used to work great but lately it can’t update or load anything new, any articles, community, etc. So all I can do is use the calendar to track symptoms and period dates. Once problem is fixed will update review. I have a new iPhone with tons of storage space and am in WiFi too so ik it’s an app issue.

    By odd sense

  • amazing app but apple watch

    By Annelyn23456
    i love flo! it is amazing! after i got my apple watch though, i was excited to be able to report symptoms from there. but, when i downloaded the apple watch app and tried to launch it on my watch, it would crash. flo would be absolutely flawless with this apple watch app
  • Awesome app and great for girls who wanna know more

    By Caps fan!
    I love this app so much! I was honestly kinda nervous about getting it but once o did, it changed my life. There are places you can rant and get stuff off your chest and places you can talk to people about concerns and problems with. The user are so friendly and non judgmental. Users are anonymous so you don’t feel pressured or scared. And I love it so much. Highly recommend if you need a place to chat or track your period or anything really. Have fun and stay safe!
  • Flo app

    By AlwaysN4evr319
    Nice app. Helps me keep track of my weight, water intake, monthly cycle, ovulation, and helps me remember to take my pill.
  • Frustrated

    By amandajolene4
    I’ve used this app for about a year and its really helpful but today I went on it and all my data and everything I had logged was just gone. I checked to see if I somehow got signed out but I’m still signed in. I don’t know how this could have happened but I’m really frustrated and disappointed :/
  • Inaccurate, got me pregnant

    By RachellovesJesussss
    That is all
  • Amazing

    By jasminejanelbaker238
    Whoever made this app is a genius. There’s a positive community for girls to talk about stuff and we all relate to each other. It’s just amazing. 10/10 I recommend.
  • Soo awesome

    By Audr3y+11+20
    There are so many girls out there afraid they’re the only one but this app helps them know that they’re not. I have talked to so many girls who go through things that are so weird. We talk about awkward and crazy stories. I wanna warn some people that people will curse.
  • (L)GBT 🏳️‍🌈

    By Beeloucinda
    Flo is one of the many apps I use to track my Period , Ovulation and Temperature . In hopes of becoming pregnant soon . I’ve just noticed there’s a community section which is the best part of it actually . It would be really nice if a (L)GBT section was added for people like me to communicate . It’s very common for Lesbians to use IUI/ICI (Artificial Insemination ) to conceive & I would like to chat with others to share experience, goals & some pointers in the process of it all . Please update !💕
  • I love this app!! 💞

    I’ve had my period since I was 11, and I’m now 16. I’ve never used a period tracking app before until this one, but I love this one! One of my favorite features is the community tab. I love being able to talk about things that are happening to my body with other people that are experiencing the same thing or similar things. I also enjoy being able to give my feedback about things I know about to others! Also I love how sensitive topics aren’t censored for younger girls, as far as things to do with sex or parts of a vagina. There are many things us girls are led to believe that we shouldn’t know about or things that we should wait to learn about, but this app gives girls of all ages a chance to find out a lot about ourselves and other women too.
  • What does this do for me that a calendar can’t?

    By whydoesthisevenexist
    I’m really not sure what the point of this app is, if doesn’t know when my period will be or even attempt to predict it... Every day of the month seems to be a “low chance of getting pregnant” but that makes no sense because you have to ovulate at some point. it will not even tell you when you should roughly be ovulating. None of the extra things are even an option to access like community or tips unless you fully purchase the app for 10$ a month which is absolutely stupid when It should just be free.
  • A Boyfriend’s Perspective

    By Molgera124
    This is amazing. There’s an entire world I was not made privvy to, and 5 minutes on this app has opened my eyes to so much I did not know about. To everybody at Flo, thank you.
  • Best app ever!!!

    By #calm16
    I love this app!! It provides accurate predictions, and a ton of valuable insights!! Also it lets you chat with girls who been there done that. This is the best app for female health tracking ON THE PLANET!!!!!!!!!!!!!!!!!!!!!!!!
  • LOVE

    By DirectionerTWFanmily
    I absolutely love this app! However I just got the new Apple Watch and the app isn’t opening on my watch...
  • Please make it for 12 years old

    By jessica's blood
    I’m just here to say please make it for 12 years old. I’m a 12 year old with my period and I’ll love to know when it’s coming because sometimes it happens unexpectedly and I will really love to know when it comes. I tried the app and it just went to 2006 and I felt really sad that I wasn’t going to be able to use this app because it seems like a pretty good app. So please I’m praying and asking for you guys to make it for 12 years old 🤧
  • This is the best app

    By kierabell
    I just started using this app today and I’ve already read stories and had people help me! Everyone is so nice and pleasant! They are definitely going to come in handy in the future! I’m constantly hooked! I even got my friend to download it! THANK YOU FOR THIS WONDERFUL APP!
  • This Tracker is a game changer

    By Elixabeth_Light
    This tracker is amazing especially when your traveling. I would recommend to any female out there!!👍🏾
  • In love

    By Feearex
    This app is so amazing! One of these days I will get the premium! I personally love all the extra information and the texts that it sends. It’s pretty great! Highly recommend especially if your trying to get pregnant/avoid pregnancy! I have had a lot of period apps in the past and this one is super simple and smooth❤️.
  • Great app but confusing

    By Kimberly Pineda figerora
    This is a great app I am a teen but it’s sort of confusing how to work it
  • This is bothering me!

    By Mariahm06
    I’m a teen ( 12yrs old) and I was born in August of 2006.the app is an amazing app but it won’t let me save my dob as 2006 even though I already have my period..I still like using the app but I don’t need to lie about my age..
  • Crashing app

    By Ekxn
    I loved the Flo app, however it recently crashed on me a lot. Please fix this issue. I rely on it to track my symptoms and I will switch to other apps if this isn’t resolved soon.
  • Was a great

    By Mrsbrat06
    This last update has messed up my period tracking and I’m not happy about it it’s difficult to understand my ovulation period
  • I would recommend but,

    By monkeysbanana123
    I love this app but I don’t like the fact that you have to be older than 12. Like I got my period when I was 10 years old and I find that young girls should be able to get these apps because I don’t think that a period is a “lady thing”. My friend got hers at 9 and she was so confused about it and for this particular app (one of the most helpful ones) I feel like you should be able to use at a young age. Otherwise I love it and that is my only complaint.
  • Amazing even if you aren’t trying to conceive

    By ellexus_
    Highly recommend this app for anyone trying to conceive and even for people who aren’t. Even without the premium there’s a lot of amazing content and the community section is amazing and anonymous. I have gotten a lot of amazing advice and opinions from people in the community and I can’t see myself ever not using this app
  • Worth it

    By Sjimin
    It takes while for the app to customize to you. After a couple month Flo told me when my period was coming almost perfectly. Really like it🥰
  • flow is a good app

    By bulldog🌸
    you should use it too.
  • Been using for 6 years

    By Jacquelyn Nicole
    Love this app! Super easy to track and log symptoms. The free insights are super helpful as well. Lately though, the app keeps changing my predictions which has been stressful. Yesterday it told me I was 5 days late, and then today it says I’m only 3 days late. This isn’t the first time this has happened. I know I’m “good” (😂), but for those who are suspicious that they might not be “good”, the inaccuracy of their late dates may cause a panic. Not sure if it’s a glitch that needs to be sorted out or what. Other than that, it’s super easy to log and track and I absolutely love the app!
  • App soñada

    By Yessikapv
    Excelente para llevar el control del periodo menstrual y evaluar síntomas mes a mes. Ideal para saber tus días fértiles si quieres planificar un embarazo o todo lo contrario!
  • First time periods

    By Alli_gymnast
    I love this app but I feel like you need to have a “this is my first period button” because girls will get it with out knowing how long it will be or anything. And tips for girls first periods would be helpful as well!!
  • great app just have some suggestions

    By Llamalover1243
    i love this app truly but i do have a few suggestions on how i think you guys could improve it. firstly, i would like a way to log contraceptives that aren’t the pill, so if you’re cycle becomes different the app will know why. i’m on the patch and would like a way to log it and even have the app remind me when i need to take it off and put it on (most patches you wear for a week and after three weeks of wearing patches you leave it off for a week) also, i recently was late like 14 days and wasn’t pregnant, i wasn’t using contraceptives yet either. i would like to see something implemented into the insights if you are late and had a negative test (or more) that it would give you reasons on why that could be. it would definitely help calm some peoples nerves if they don’t know what’s wrong. i definitely have more suggestions but i don’t wanna over do this so, i’ll leave another review after the update that’ll maybe have some more suggestions
  • Great app. It’s so accurate!!!

    By gigsfyghj
    I love this app it’s literally accurate every month. And I love how there is a community that we can all participate in and share our thoughts. The only thing I don’t like about the app is that I don’t get my notifications most of the time when someone responds to one of my post. Can you guys also make it where if we delete a comment from someone’s post can we not get notifications anymore from the persons post? Other than that, great app!
  • I can’t even use it

    By shininqm00ns
    I can’t even use the app! I was born I’m 2008 and I just started my period. I wanted to track it but the years only went up to 2006. I’m disappointed. Younger girls can get their periods too, I am currently 10. Please change this.
  • Annoying!

    By GeekyGirl007
    I turned off health insights not long after I downloaded this app last year. I hated the health insights because most of them were irrelevant and a lot of information was incorrect. I learned I could just go into the settings and turn it off, so I did and I’ve been loving the app ever since-UNTIL now. Every time I’m on the app, a bubble pops up with a tidbit of info and encourages me to use health insights. I tried to go back into settings to see if it got reset and I could turn it off, but the setting to do that is gone. I turned it off to begin with for a reason. If I wanted to use health insights, I’d use it. I don’t want to use it, so please stop harassing me about it with all the pop up bubbles. I just want to track my cycle, not be bothered with pop ups begging me to use a feature I don’t want every time I come onto the app. Asking once is enough, no means no. Please help me get rid of these. Seriously thinking of just deleting this app and finding a new one. So tired of fighting with the stupid insights, and so tired of apps harassing you constantly to use this feature or try this new thing. I just want to use the main feature and be left alone. Health is a very personal thing and I shouldn’t be harassed constantly while trying to do something to better it.
  • Why go paid?!

    By Sofi 2.0
    I’ve been using this app for years. Just signed back in and was told I need to pay. No thanks. And enjoy all the data I’ve put into the app. What gives?!
  • Tracking works great but the daily information is kind of sexist

    By Macwad1
    There have been several pieces that I feel are not sending the right information to young women and teenage girls. Several articles talk about the necessity of wearing some sort of bra. Bras can make it more comfortable but women should not feel that it is necessary for them to wear them all the time. Other pieces have talked about exercise and how women shouldn’t exercise to much to avoid getting bulky and others attach shame to having obvious muscles. This is not ok. This is shaming women and reinforcing the idea that women can’t get super strong. I love the app otherwise but am very disappointed by the messages being sent.
  • Love this app!

    By terelly
    I’ve used this app for a couple years now and it’s very accurate. When I got pregnant (the first try) it was because of how well this app works. Once pregnant you switch over to the pregnancy app and it’s amazing. I loved all the articles and quizzes it shared. Will definitely continue to use.
  • Five stars

    By Lolaglog6
    Flo has always been spot on with my period and even helped me get pregnant!
  • One of the best apps...period (sorry, pun intended)

    By Just.p
    I can’t wait for a doctor or nurse to ask when my last period was and actually be able to answer them! I even forgot to log my period for two months and Flo still predicted the correct date for my current round. Love this app!
  • G

    By kkgumdrops
    It helps u if u don’t remember what time ur period came on it tell u if u have a low chance of getting pregnant
  • I'm offended

    By Tarapsh
    The reason I've given this app 3 stars is not because it has bugs or ads. It's actually a very useful app with great graphics and it's easy to use. The reason I gave this app a 3 star is because of its new community part. All the topics are for straight people and it's so rude! I mean how could Flo's team not even think that there are some homosexual users using this app?!? Every topic is filled with straight people talking about their sex issues because the topics are made for them! But where can we talk about ours?
  • Paying for “Premium Content”

    By Hannah6729
    I love Flo. It is pretty good and accurate at tracking periods. There’s also a community page for discussions and articles about periods, puberty, etc. I was scrolling through and saw “Premium Content”. Tried to click and it asked me to pay for it. I understand they have to make money somehow; but i don’t have an extra $10 every month to read articles that are potentially helpful! Just found this annoying. It’s applied to most articles to. If younger girls have this app and aren’t sure how puberty works or have questions they could come to the articles. But one problem. Most of the ones thatseem helpful cost money! What if they’re embarrassed to go to their mom, aunt, or grandma??? Ugh. Otherwise i do like this app. If you can respond to me that would be great. Thanks for reading!
  • Monthly fee :(

    By Someone special: )
    I thought it was free, then when I started using it I found out there was a monthly fee!
  • Love this app, but...

    By JC_Santana
    I love this app. The only downfall after using it for a year is that they are staring to charge for “premium content” which never happens before. I really hope it remains free for the most part it gives a lot of helpful insights!
