Paramount to My Conception
Update: I had no idea this app turned into a pregnancy tracker after you miss a period. Amazing!!! Adding 1 more star for a full 5 star review. I still think the free content is far better than the paid content and the anonymous chat should go away, so much negativity there.
The free features of this app are a million times more valuable than the paid features. The period and ovulation tracker was paramount to my husband and I conceiving - I’m terrible at keeping track of these things on my own (usually my period just sneaks up on me). The symptom tracker and the “dive into your cycle day ##” feature were especially helpful in recognizing that I was showing signs of being pregnant, rather than just experiencing PMS. Because the free features were so helpful, I tried the trial of the paid version and was very disappointed in what it included. Especially the “chat with other future moms”...oh my goodness, get rid of this, it’s just a platform for women to work each other up into frenzies over trying to conceive. It’s comical at first, “anyone else want to conceive so bad they imitate symptoms?” and then sad, “I’m crying at work right now because two other women are pregnant and I’m not”, and if you keep reading it starts eating away at you...everything posted is so negative.

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!

You can disable the metric system mode, if you follow these steps: More > Settings > Unable metric system.
Hope it helps!
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.
