I love this app and I would highly recommend getting it. It’s always been super accurate in predicting when I’m gonna get my period (I’m pretty regular but my cycle is quite short) and it helps me get to know my body a little better. The tracking feature is really useful so you can keep a note of any changes. The “Secret Chats” are super fun too! You can get other people’s insight, opinions and advice (which can come in handy!) in a safe space. It would be useful if there was a setting where you could switch to gender neutral pronouns because I know there’s probably a lot of peeps out there that want to track their cycle but are uncomfortable with the female pronouns.

Good but should be free

I have been using this app for years and it’s been a really good experience. I have really learned a lot about how my body works & the predictions are usually accurate. I do have one criticism about the app and that is the premium subscription option. This information about s*x, periods, body changes, birth control etc., should be free. This information is so crucial, really informative & most importantly modern, younger women should not have to pay to a subscription to avail of this information. As this platform may be the only education and place where younger women can get accurate, non judgmental advice from. It’s really important to consider this as every woman has a different experience in life & not able to pay for the subscription due to privacy, financial issues etc.

Hi Laurynnnlda! 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.

New Premium Barriers
07/11/2024
🪷 Millie 🪷
Flo recently introduced a new version of their premium subscription model, which creates barriers for women seeking accessible information about their own bodies. While basic tracking features remain free, many of the app’s more detailed health insights, cycle analyses, and educational resources are now locked behind a paywall. This includes learning about your own symptoms to expect and even requesting a doctor’s report, which is utterly shocking and shameful. This shift means that women without the means to pay for a subscription may lose out on crucial knowledge about their OWN health, leaving them without guidance on important issues like irregular cycles, hormonal changes, and mood issues. By restricting these insights to premium users, Flo limits access to essential information that could empower women to better understand and take control of their own health, potentially worsening existing health inequities in this current society. Especially considering recent events. Stop taking away women’s rights.

Developer Response
Hi Millie! 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.

Brilliant app. Recommend to everyone 🩷

When you remember to record all your symptoms or areas of distress, the app keeps track of your patterns and predicts how you may be experiencing or feeling based on the past patterns. Out of all the apps I’ve tried flo has been the most secure and reliable one. I have had it for years now. Even the little bot that helps talk with you through your discomfort to find a cause (not medical advice ) just options to help with your worry, that you can then take to doctor if required. It eases my anxiety rather than the awful Google searches 😂. Very good app! Highly recommend.
