I use it constantly during my period
I found this app a number of months back because i was having a super abnormally long period and i figured it was probably about time i started actually tracking my period. So i got this app and ive now been using it for months and ive continued to really like it and recommend it to my friends. I love being able to see roughly when my period will start as well as be able to scroll through the little mini articles (because honestly my health class in high school taught me nothing about anything going on). The one thing that isnt perfect is the prediction cycle. Its never been accurate for me even tho ive tracked my periods for about a year now. I mean, its usually really close and is maybe just off by a day or two so i dont actually fault it, but i do think people should recognize that this app isnt absolutely accurate because its still using an algorithm that’s never going to know what your body is doing 100% of the time. My one other thing isnt a complaint its just i would love to see a feature where we can bookmark insights. I love the insights but i’d like to do more than just like them. Or is there a feature already and my blindness has just kept it hidden from me lol
Tldr: great app, not always accurate, would like to be able to bookmark the insights, but no matter what its still super easy and great to use, i highly recommend
It’s nice but...
So I used this app for my period And it was great up until my period change and I came on a week early which was perfect for my weekend away because we were planning to get pregnant and my ovulation date was set for a specific day. Well I was on my period a day or two longer so I figured it would probably change my ovulation date. Well my trip was set to be at least about 2 to 3 weeks away and I kept checking the app to make sure and to see if my ovulation date was going to change well it didn’t change it stay the same and make sure that I refresh my app just in case and it stayed the same. Now the day I get to my destinations for my trip is my ovulation day that was on the app that’s what we were depending on. Three days later I go on the app to mark the fact that we made love and the ovulation date changed to the day before I arrived on my trip. Immediately I was upset because it seems as though we may have missed the ovulation day due to the fact that the app didn’t update until after my ovulation date that was set originally. So I deleted the app because of that. It’s very upsetting when you’re trying to get pregnant and your ovulation date just seems to change along with your fertile days changes I just think that that is something that they need to look into I no longer want to use this app.

Hi there! Thank you for your feedback. Could you please contact us directly from the app (More-Contact support), describing your problem and without deleting any symbols from the message so that we could help you.
Best regards, Svetlana.
this app is super useful for tracking periods, and has given me mostly accurate predictions so far! it’s been off by a day or two a couple times when i first started using it because it wasn’t adjusted to my cycle yet, but since then i haven’t had any issues. i love the insights where it gives info about my period and the different changes that come along with a period, and i especially love that you can comment anonymously on posts and get help from and give help to the community. by far, my favorite thing about the Flo app is that you can have it give you reminders to drink water, take meds, and weigh yourself if that is something that you’re concerned about! the reminders are super helpful for me as my meds are for adhd, so i need a reminder so i actually remember to take them lol! the only thing that i would adjust is that my water bottle has metric markings, but i live in america, so i have to convert the metric to ounces to track my water because the only way to use metric for water is to switch the entire app over to metric. this isn’t a huge deal because google is a pretty good converter but it’s just something that i’ve noticed. overall, this is a great app and i’ve recommended it to friends and family, and now i’m recommending it to you!
