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!

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.

Definitely the best period app.
After I got my first period I used the same app for years to track it. It never predicted my period right. For the longest time I just figured I was super irregular as many girls are when they start there period, but eventually I realized It said I was consistently late by approximately the same number of days every cycle. I just dealt with it for awhile. When I finally decided to check for a better period tracking app I found Flo. This app is SO MUCH BETTER!! It usually predicts my period pretty accurately, sometimes spot on. When my cycle shifts it always makes adjustments and often becomes more accurate. I also love that it doesn’t mark your period late until A certain number of days after your cycle was supposed to start (I think 5, which is the “official” number of days that make a period considered late. It doesn’t just mark it late when your period doesn’t start the day it was predicted to. I was especially impressed when I missed a period after my wisdom tooth surgery and when I logged my next period the predictions continued to be accurate immediately after. It seems like the developers did a great job on the actual software as well as put lots of thought, research, and expertise into it. It’s a great app!!
