Hi, This is a great app and I would’ve given it 5 stars if they had the option to remind u of your period 1 or 2 weeks before. Menstrual migraines are very common and once we get our period and a couple of days before that, our productivity goes down to almost zero and the frequency & strength of the migraines double. Our tasks start piling up & we miss out on deadlines. Huge stress. It would change my life (no joke) if we get a reminder before so we can manage our life in such a way that we leave less work for the two weeks of menstrual symptoms. Maybe add a goal to the app to track menstrual migraines or something or just add a notification option to get reminded of our period 2 weeks before it’s there. I hope you take my suggestion in consideration. Otherwise, thank you for the great experience & accuracy!

Flo review
My Flo experience
I’ve been using flo for over a year now. So I downloaded it a few months after my first period. Of course my period is irregular, do no period tracker could ever accurately track it each cycle, but flo is always accurate enough and the variation is minimal so i know it'll come within that week. The secret chats are great. I love connecting with other girls with similar experiences. However, the only thing i dislike is that you cannot use the assistant bot thing without having to pay, which is understandable, but sometimes it can be useful for the bot to give just basic information, nothing specialized or detailed without having to pay, especially for girls who don’t have access to that type of education.

The app is great but
Yrrefai
Ive been using this app for 5 years now and its very precise tracking my period and ovulation but it keeps giving me notifications to subscribe to premium and usually when I like an app i don’t mind upgrading, but with this app i don’t know what im updraging to, premium features are not clear and the user wouldn’t know if its worth upgrading or not without at least a free trial specially for old users since the subscription is not cheap. Giving me 85% discount still does not make me want to subscribe because I don’t know what else would the app give me in benefits. Overall I think it works perfect for tracking your period and pregnancy without the premium but again I don’t know what are the “premium” benefits.

Don’t like the new feature
Yasyours1
I relied on flo to let me know when I was going to get my period and to understand my fertility rates. Now, with this new feature, it hides your chances of getting pregnant and wants me to pay for premium?? Why are so many features being stripped away, making it a good app that is becoming frustrating to use from the constant premium notifications and all the features slowly being removed. These features help young girls understand themselves and their bodies. Why should we pay for this? I loved this app but now I’m considering using another.
Developer Response
Hi Yasyours1! We understand you’re upset that some features are now available only on Flo Premium. Funds from our Premium subscriptions allow us to keep building and improving the app, while keeping basic cycle tracking free for everyone. We welcome your thoughts — email us at support@flo.health Kind Regards, Flo Team
