Ratings and Reviews
Not a fan of new format
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.
Developer Response ,
Thank you for sharing this. We’re sorry to hear you’re disappointed that we moved some features out of the free plan. Premium subscriptions fund the ongoing development of the app, while keeping the basics free for everyone. We welcome your feedback. Please email us at firstname.lastname@example.org.

Good, but bugs
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!!
The #1 complaint you’ve had
It really is sad that the premium feature is even necessary for this type of thing. I feel the best way to make money would be by maybe adding ads, or maybe people could buy a premium where it just customizes everything.
One feature I feel should not be paid for, is the thing where you can talk to a professional about your health issues, or trying to find a specific article to read for a major problem you’ve been having, and to see how everyone else has dealt with it. As a woman and tons of other woman who use flo, feel like crap about this. Flo wasn’t just about tracking, it was about relating with all the anonymous people about basic woman problems that are to uncomfortable to talk about in real life. It really saddens me you have done this, especially when the “AI message” or whatever, says something along the lines of “your period is off” or “there could be medical problems, and then let that “AI” continue the conversation, and then wait until the end to tell you to buy premium. I just feel you have many ways around “keeping the basics free”, at least give some things back to us and make more things for people to buy, that are unrelated to something that should automatically be on your app to help women. I know it’s been two years of people saying this on the reviews so this probably won’t reach far, I’m just hoping in some way it’ll be better😕
