We have to pay for many things in flo, it’s not so cool but once you paid, it’s incredible

Developer Response
Hi there! Thank you for sharing your feedback about Flo. In this latest version, we updated our algorithms to make Flo’s predictions even more accurate and useful, and we enhanced personalization options for Flo users. We also moved some features from the free plan to the Premium plan, which is why you may have seen paywalls prompting you to subscribe to our Premium plan to access certain types of content. Even with this change, the core features of our app (cycle tracking and prediction) remain free for everyone. We believe cycle tracking should be available to everyone who needs it, regardless of ability to pay. For users who are interested in our more advanced options, the funds we receive from our Premium subscribers enable the ongoing development of the app, and help keep the basics free for everyone. While some apps push ads and sell user data to make money, we are committed to remaining ad-free and keeping our user data safe, secure, and protected at all costs. Thanks to our subscription-based model, none of our users see annoying ads, and your data is safe and secure — regardless of whether or not you’re a subscriber. While we started out as a period tracker, we’ve since expanded our vision to become an all-in-one deeply personalized, holistic women’s health and wellbeing platform. We now have a team of over 450 passionate, dedicated employees and over 140 medical and health experts from medical schools and hospitals who make sure all the content in the app is medically credible and evidence-based. Our product managers and engineers work diligently to create a deeply personalized experience for our users and ensure that Flo is tailored to your needs, goals, and symptoms. Lastly, and most importantly, our data and security team implements best-in-class data security standards. We encourage you to check out Flo Premium. Each day, you’ll find personalized actionable tips based on your unique cycle phase and changes in hormone levels. Our Insights section also offers a robust, searchable library of multimedia health and well-being content We aim to take female health to an entirely new level and hope to make our app even more useful and supportive for you.

just a girl 😔
I am really disappointed by the recent changes to Flo. One of the reasons why I loved this app was because it offered so much more than just period tracking. The articles, discussions, educational content, and community features made it unique and incredibly helpful for millions of users.Now, it feels like almost everything has been placed behind a paywall. The only major features left for free are period predictions, cycle logging, and symptom tracking. While these are useful, they are only a small part of what made Flo such an amazing and popular app.I understand that premium features help support the platform, but it is unfortunate that so much valuable content is no longer accessible to users who cannot afford a subscription. Not everyone has the financial means to pay for one.I hope Flo will consider making some of these features available for free again or introducing more accessible options, so that everyone can benefit from the resources that once made the app so exceptional.

It was so far the best app in terms of interface,simplicity and accuracy. The insight was the most helpful and it helped you track every little change in your vgnal health, and it was free the premium would allow you to invite a partner. But know you have to pay if you want the insights now you have to pay basically the only thing that you can do now is log your period and your symptoms and every other app can do that.
