I used to love flo. I’ve been using the app since my junior year of high school (I’m now a senior in college). I appreciate how I’ve been able to track my period through the years, as it’s been enormously helpful to my overall health, well-being, and awareness of my body. That being said, I have really struggled with the new updates that flo has undergone. Not only has the app become significantly less user-friendly, but the constant push to “go premium” has really negatively impacted my experience. I understand why they have a premium option, and I respect that it is there, but what I don’t respect is how I’m constantly being mislead in order to be trapped into signing up for a premium subscription. I find it really irresponsible that women who don’t want to pay for this app, will be given insights about their menstrual health, only to find out that they can’t have access to the information behave they don’t have an account! I used the chat feature a few times before, and it’ll leave me responding to chats for about 5 minutes, and right before they give me an answer about my health, they say I need to subscribe! It’s honestly cruel that an app meant to help women feel more secure about their health, is constantly misleading them like this, or trying to buy their desire for basic health info! Most of which can be googled, btw. I’ve really loved using flo, but am honestly considering shifting gears if things don’t change soon.

Gave a 5 star so this will be seen.I have been using this app for well over 5 years, it used to be so great and user friendly. And I really appreciated being able to track my cycle and have insight as to what I was going through, all the way up to when I got pregnant early last year with my daughter. & then the app didn’t really have much to offer compared to other apps as far as tracking my pregnancy. I redownloaded the app once I started having periods again postpartum and every so many minutes within using the app, it prompts me to purchase the full subscription to be able to use even basic features that used to be available to everyone without purchase. In addition, when it prompts you to make a purchase, it literally forces you to agree and continue into the purchase by not allowing an exit button or anything to back out of the ad until you’re having to deny the purchase when it tries to ask for a payment method. It’s ridiculous that they are so money hungry that they now feel the need to try to force you into a purchase. It will also offer insight on your cycle but then pop up with an ad that you need to make a purchase to even see the insight. Other than being able to enter when you have your period and look back on the calendar, it is now a pointless app, I can literally use the calendar on my phone to do the same thing.

JESUS LIVES!!!👑
Jesus loves you guys, thank you so much for helping me with my period. 🩸💕God loves you so much and He saved me. I actually used to blame God for my period, but now I thankfully know that it’s not because of Him and anything that’s bad isn’t from Jesus, who is God. Anything good or important that comes from periods is because of Jesus, for He is the source of everything good. Even though it’s our faults that we allowed sin into the world, which allowed bad things and evil into the world too. Jesus still allows good things to come our way from those bad things, and He does with periods too. I wish I could give all you ladies like a years worth of the best pads and heating pads for cramps for your period, but just know that it’s gonna be okay and you’re all strong and admiral for what your body does to prepare for you future baby. I’m pretty sure there was a woman in the Bible who was bleeding for 12 years, and since she put her faith in Jesus and that even just touching His robe would heal her, He did. And she was blessed just everyone else is. I know that we can be annoyed or even jealous that guys don’t have to go through this, but if you think about it. That just means that we’re stronger in another way and our bodies do something incredible. I’m not trying to downplay the pain, I just wanna let you guys see the good from periods and how those good things are from the Lord Jesus Christ. God bless you! ✝️🙏🏼📖

Jessand!
I really like this app! It helped me track my cycles and ovulation when I was trying to get pregnant, and then was super easy to swap over when I was finally pregnant! And the pregnancy side of things have been so good!!! I love opening it every day to find my new tips and advice for the day. It also helps me track my water, which I love.But, the new updates it has gone through have been sort of weird. It always prompts me to input my weight to track it, but that feature is gone! There is nowhere for me to input my weight anymore. Also, the chat feature is gone! I liked the “chat” at the beginning of every week even though you can only respond with pre written responses, it was very informative and useful. One week of pregnancy was incorrect (said I was week 8 even though I moved on to week 9) and it didn’t work because it knew something was wrong, and now I haven’t seen it since. Lastly, I loved all the of “stories” that it gave me during first trimester. A week to talk about exercise, a week for nutrition, a week for working while pregnant, etc. but as soon as second trimester hit, there’s nothing! I really looked forward to reading it everyday, but now there’s just a lack of information. I begin to wonder what I’m getting by paying “premium” because it sort of stopped all of the major things it was helping me with. But I loved it, so I’m mostly writing this review to let the creators know what they need to fix and bring back!!
