The app tracks periods which is great. The last 6 months the app has really pushed to purchase a subscription. I understand it's how it keeps running and makes money. I just feel slightly annoyed that it pushes so hard and has started to take away from some of the free information it use to give. It seems every update gives less and less for the free version and just keeps pushing more and more for a monthly subscription.

Hi Brandi! Thank you for your honest feedback. Premium subscriptions help us provide advanced features to those who value them and keep basic cycle tracking free for everyone. We invite you to continue tracking your cycle and share your thoughts with us at support@flo.health. Best Regards, Flo Support Team

It's a nicely organized app, but you can't make notes or do much besides track the days and if you exceriszed, basically. Not a whole lot with the free version. It's extremely annoying how pushy they are of the premium subscription! Every second pops up an advertisement for paying $15+ a year or $10 a month just to track your period with someone else's opinions! I'm going to find a different app to use that won't shove their subscriptions in my face and gives me what I want. I don't recommend.

I don't pay for premium, but I've been using flo for the past couple years or so and have enjoyed it. The period tracker function is intuitive and useful, and I could see being able to track symptoms on a month by month basis could be useful. By far what I like most is that after a few months, it starts to predict when your period will happen again, which helps me to plan better.
