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.

Overall it's not a bad app, it doesn't like to load and when it does it takes forever to do so. I have to back out of the app and go back in to see my saved symptoms. I also don't like that it claims it's free on the download and when you search for free tracking apps this one comes up but wants you to subscribe for $49 a year. It tried to charge my card even though I didn't set up a subscription method. Thank goodness it didn't go through.

Hi Jenna! We’re sorry to hear that! The only way a user can sign up for a subscription is by tapping Continue on a screen that offers Flo Premium and confirming their consent with their password or Touch/Face ID or by subscribing at app.flo.health. If you contact us directly from the app (Menu - Help - Contact us), we’ll be happy to help! Flo Team

Used this for years. I have repeatedly attempted to turn off superfluous notifications, especially about offers and Premium-locked information, yet the app continues to send them to me. Today I got a notification about orgasms right on my phone where anyone could see, including my STUDENTS. It also hardly ever sends me the notifications I ask for about the start of my period. Yeah, it'll track and predict my period, but I'm sick of all the extraneous stuff, so I'm switching to a different app.
