Can't get enough of it

This is an awesome application! I love the articles so much and I love the tests. I really like the way it works (when you log your symptoms a related article pops up) it's so educating and fun to use! Not to mention that I did not use to drink much water before using this app and now I'm so motivated to drink as much as I should. I simply love it!

Whether it’s the sign up for premium pop-ups or not, there’s so much going on. The app feels overwhelming sometimes, it’s annoying. I’m just trynna check how late I am, I don’t want to sign up for premium every time I get in the app. Otherwise no complaints.Maybe make sure the chats are monitored especially in regards to content warnings. Place some trigger warnings or something. Thanks for listening

This app is great I have been using to track since the dawn of time, but please oh god please stop asking me to subscribe, at this point it’s like badgering when all I want is to just log in the days. I have health insurance which I already pay for. At this point I am thinking of deleting and going back to the olden times of just tracking on calendar.

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 120 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. If you have any other questions, please reach out at support@flo.health. Your feedback is truly valuable, and it helps us improve the app for you and for many others around the world. Kind Regards, Flo Team
