  • Very good app

    By donnarenad
    I was irregular and would sometimes skip. But this app allowed me to track my next period accurately up until God made me regular. So a woman of God prayed for me that my cycle would come on and be regular. And every since then I been regular. Very good app.
  • Great App, Terrible customer service

    By blvckMermaid33
    The app is great, but the customer service responses are very robotic. Almost as if they don’t even read what you said, and just copy and paste a generic answer. I submitted a complaint about how the secret chats should be moderated more, and how certain topics shouldn’t be allowed in the chats (I.e. religion) and all they sent was the forum rules. No words discussing what I was complaining about, or apologizing for my discomfort. Religion may not bother all people, but I don’t think people in the app should overlook possible health concerns because it isn’t in gods plan for them according to some commentators. Basically, use the app for the tracking and the helpful articles, don’t use the secret chats for any reliable information.
  • Need PAY version to get period prediction

    By Winzertart
    I used this app to track and predict my period cycle. But the latest update REMOVED all future period prediction features, unless you sign up for paid subscription. So... buh-bye... switched to a different, more popular free app.
  • Shares info

    By 012345nicknamesallgone
    Not interested in using an app that shares info with Facebook, about menstrual cycles nonetheless. So silly. Can’t anything be private?
  • Needs work

    By Asilva315
    Ive been using this app for a while. Everything was going great until I forgot to track a period. I tried everything to input a date and it won’t let me. All I get is that I’m 20 days late. It doesn’t even show me when my next period should be either. It’s gotten so frustrating.
  • Not iPhone XR compatible

    By TheStrugglingOptimist
    Upgraded my iPhone. If no longer opens - splash screen for a second then crashes. Pity. I loved it.
  • Used to love this app before they decided to sell all my data

    By PrincessPrune
    I wish I could submit a screenshot of the ridiculous permissions screen. The data I put into this app is incredibly personal and the thought they are now forcing users to agree to those ridiculous terms is so disappointing. I will say though, at least they are being honest and upfront about it, many other apps are not. Still though, deleted the app, so incredibly sad as I had such a great deal of data I was using with my doctors to help with some issues.
  • Add more ages

    By Alysa400
    I like the app design but i wanted to know if you could add more ages because the ages for puberty is 8-16 a 12 or 11 could have a period and not be able to use this app. But over all it’s a great app i do recommend ☺️
  • 🏧??

    Why do I gotta pay money..
  • Accurate

    By loladeaina
    My period is irregular but this app is very accurate
  • Women Around The World

    By OrangeAsterisk
    There are so many factors to consider during a woman’s period. Mine is every 1-3 months, due to my diet and genetics. Please consider other worldwide contributions. Research the affect of foods on American women’s diet, and other organic foods.
  • Love it, could add to it though

    By Apostolicgirl:)
    I love this app. I’ve been using it for a few years now. It is usually very accurate give or take a day or two. The one thing I would suggest is adding a couple more symptoms. I looked for a place to give feedback other than here (because this is public) and I’d rather not put my suggestions on here. But other than the suggestion I have, this app is super great!
  • Very Helpful

    By Floof n DoofYT
    This does help track your period and all that but (this is a very small thing) I am unable to set my birthday as December __ 2006 and I’m just wondering why this is..?
  • Nice app

    By Ayania's mom
    This app is very good. Had it years ago phone killed over and lost all my info. Glad they got the email option to link account. Very good at predicting.
  • Not Accurate-I got pregnant!!!

    By Bad A** Mom Rae
    The ovulation calendar on this app is not accurate!! I got pregnant the first month using this app. The app that I had been using for years was decommissioned, so I decided to give this one a try. When I conceived, I was thinking “there’s no way”. I checked my dates against another app and WebMD and their dates matched each other, but this app was 3-4 days off. My ovulation date according to WebMd, was the exact date I got pregnant. Although it was an unplanned pregnancy, I have a beautiful newborn now. If you are trying to conceive or prevent pregnancy, this is NOT the app for you! Hope this review helps someone.

    By May_et
    They say it’s inclusive and yet every sentence in this app screams female. Lots of “she’s” “women” and “lady” in their vocabulary. Please realize there are people that don’t identify as females and have periods. Also the lgbtq+ forum is slim AND there are people in the forums spreading transphobic hate. This app needs to do BETTER.
  • This app is amazing and accurate!

    By bayleenanette
    I downloaded this app a few months ago since I’ve been trying to get pregnant. I have PCOS with very irregular periods. I started to take ovulation test and I finally got a positive one on the day the app predicted. I also appreciate the information and articles this app provides.

    I love this app I’ve had it for over a year, and it’s very accurate!
  • Accurate

    By KuromiM
    This app is pretty accurate.
  • Too slow

    By Meyouandwveryone12332
    I never write reviews but even though I love Flo and makes everything easier, idk why my app takes forever to open and it crashes every time I try to open it.

  • Good

    By asdfghtedcvr
    Yea this app is very good and accurate
  • Crashing

    By crouchingbear
    I love this app for period and ovulation tracking! It’s very accurate! However when I try to add new symptoms under each day this new version of the app crashes on me.
  • Be careful with this app

    By soleililiy
    Whether you intend on spending any money or not it will get you. I even deleted it and got charged on my card many months later. It’s hard to notice if you have a lot of spam emails etc, etc. Best not to start this mess . . Find a safer way to track your period ladies, sorry.
  • Period & lifestyle

    By lep73
    I like tracking my menstrual cycle, symptoms and feelings. I find the articles interesting & credible for women’s sexual health. I wish I could track pounds - it only offers kg. That may be the reason if I leave the app but I really like it so far.

    By idkdianabieberrrrrr
    Flo is my GO TO! i get a new phone i automatically install flo. it’s such a fast and EASY way to track your period, when it’s coming, and facts about your moods! I’ve had this app for almost 2 years and not once has it EVER caused problems ! no ads , no pop ups , and no real purchases !
  • No 2007 selection

    By Horse quest fan
    My birth year is in 2007 and I need help tracking my days but there’s no 2007 year like cmon dude there are people born in 2007 too
  • Amazing app that does more than track your period

    By WaffleRates
    I don’t ever write reviews. However, I have used this app for years. Recently my period has been strange. Flo was able to notice and gave me a quiz and suggested possible reasons why. Afterwards, I went to the doctor as Flo suggested and the doctor asked the exact same questions as the quiz and was able to perform some blood tests. Flo followed up after and asked if I went to the doctor. I answered the quiz saying I went but was waiting on test results. Flo provided an article on what to do when you are anxiously waiting on results. This is absolutely a human centered experience and I greatly appreciate this app.

    By onlyhonest rev13ws
    I’ve only just recently downloaded this because I had been scared of people knowing but that was when I was around 10, now I love this app the other females on this app are so encouraging, helpful, and uplifting. Luckily there is a lot of doctors/gynecologists on the app who are always willing to anonymously answer anonymously asked questions. One suggestion would be to lower the age range because there are many young girls who start cycles early and have many questions they are scared to ask people in their lives. Minimum age of thirteen should be lowered just a few years because my young sister was taken to the hospital many times because she was scared to ask questions about her vaginal health which might be the case for a lot of girls from 8-10

    By Misstasha1229
    It gives you notifications about when your period is about to start and there’s lots of articles about things that happen during other girls periods and if there’s anything unusual happening you write anonymously about it and other girls who have experienced it will reply! It’s very helpful and gives you lots of wonderful tips and about things like cramps, etc. I totally recommend getting this app because it is so worth it and you definitely won’t regret it!
  • Good for period tracking not good for tracking pregnancy

    By Chelsea8192
    The app works great for tracking pregnancy. But once I got pregnant I started noticing problems. The app does not adjust the gestational age based on due date. The app deleted my pregnancy and I had to readd it but now it won’t let me adjust my due date because it thinks I JUST got pregnant. So for example it thinks I just missed my period and am 4 weeks pregnant when I am really 4 MONTHS pregnant. There is no way of changing this. Only use it for tracking periods. Otherwise it’s useless.
  • Toxic

    By celstiel
    So I’ve been using this app for a while but I wanna delete it now the way the users talk about boys is disgusting all i see is boys have is easy they need to stop cry men always cheat men keep objecting our body’s and then they objet men/boys body and I’ve seen them say boys/men are bogs who need a leash or men can’t get raped or abused like this app is why most girls think it’s ok to say this and it’s not it something called toxic femininity and that needs to be shown and talked about on this app and the things that the girls talk about boys and men like that disgusts me and it a wrong to day that just because your a female doesn’t mean it’s ok this should have been delivered to the users who are on FLO you the fact you still let it go on is horrible I don’t even use this app anymore.
  • Charged by app by mistake

    By ShortymattShorty15
    Hi, I'm Ahjanae I really don't have a problem with your app. But there has been a mistake. When doing the free 7-day trial and when canceling the trail on the second day. I still received a bill of $49.99. This is a problem for me because I'm only 16 and I did not order or paid for anything for this specific app. So I don't really understand or quit get it; on why I'm being charged with such a huge bill. If you can get back to me, that will be great
  • Review

    By AG2917
    I love this app! I have gotten pregnant twice with it. I love that it has a pregnancy mode. But I forgot to log my last pregnancy so I would like for a spot to be added to where I can put when I was pregnant on it. That way it doesn’t count it as a missed period for so long!
  • Due date miscalculation

    By haro85
    Miscalculated my due date by a whole week. Not sure what the glitch is....
  • Not free . Subscription required

    By Dayshaaaaaaaaaaa
  • Was good once now not so much.

    By 08Mag
    This app use to be helpful. I begin using it to track ovulation. The articles and tips use to be relevant but no longer are. They use to give some helpful info regarding TTC and tracking ovulation overall. Now the articles are all focused on birth control which obviously isn’t helpful if your TTC. I no longer see the benefit of inputting my personal data since everything generated does not pertain to my intended use of the app. It no longer feels like the app is responsive to the data I input it’s very generic. I do not find the community convo helpful no useful discussion there either. Currently looking for a replacement app.
  • Not great

    By Iolokus
    Uses bizarre language and doesn’t provide any real health insights. Skip this one, especially for pregnancy.
  • Good app

    By mustbe_jordyn
    I like the app because it is simple to use. It could definitely use more symptoms and a more personalized feel, but an overall good app. 3 1/2 stars :)
  • Help me

    By Lavieenveuve
    More than you are
  • My period

    By theGMidget
    It is sooook blooooooory I squirt blood
  • Great app for tracking cycle

    By NQuigley
    I really like the simplicity of this app. Especially when taking contraception to keep up with mood changes and differing flows.
  • Update

    By Pepperoni Cake
    Every time a new update is released the app has problems. I still can’t access health insights.
  • Age

    By rhin()
    this is ok but it’s not great for your first period and you have to be at least 13? some girls start at 8 and you have to be 13? i don’t understand. i’m 11 and i started on the 6th and was a little frustrating by the age thing. anyway, good for people of age.
  • needs one more thing

    By hziwhebcisgenfoshajfjiwja
    I really enjoy the aesthetic of this app! I just wish there was a PMS option that predicts the days you will PMS. I just transitioned from the Clue app and I like this app because of the choices of parameters you can choose from. I also think being able to choose your own background and bubble colors would be very cool. Thank you!!
  • Every female isn’t an adult

    I have this app for my 11 year old daughter, it’s great for tracking and predicting her cycle but those adult questions. Why would you want to know that much about anyone. That’s just gross
  • Best App ever, keep improving!

    By Izzybeegone
    I LOVE this app! It’s so convenient, helpful, and accurate. The best is all the free advice on sex, contraception options, and just general health tips. I feel like it’s helping me get the sex ed that my public school system failed to. My only criticisms are that as of now, there isn’t a way to search questions in their “secret chat” sections, and you can’t post questions of your own. Overall, Flo is an app doing amazing work!!
  • good but some things could change

    By qazhrhsjhdjsiwhr
    i really like the app! I got my first period when i was 12 and decided to find an app to track it. Flo was the most recommend app so i downloaded it. after i downloaded it, i looked at other period tracking apps. this was the best one! i really like that you could also put your symptoms down and also print out your cycle report. things that need to be improved: • they need to add more emotions • they need to add if you have any mental health issues, one of the options is “anxious” but if you have anxiety/depression then that could vary for you •i dislike some of the things they speak about in the “community” chat and some of the things make me feel uncomfortable (i do also like the community chat because i can learn a lot). but maybe have an option that you can choose what your comfortable reading and what your not •change the age down to like 9! Some girls get there periods at the age of 9 •make courses free!!!
