loved it for years. Even opted for the premium version of the app, when there was just a premium version to unlock additional features. Stopped using it for a few years since my BC stopped my cycle. The new app is too busy & constantly pushing a premium subscription, when I already had a premium version of the app. Im not interested in all the extra articles, sex ed advice, or the billion other things crammed on the home screen going to find a new app, this app just has too much going on.

DEVS: I dislike the new icons, Not inclusive anymore. The update added way too many options. I want to track my period, not do homework. Make it fast with minimal interruptions unless important! The premium bot assistant is repetitive and won't close. USERS: Skip it unless you are okay with paying for premium. Im premium but free users are locked out of helpful articles and hounded with ads. Constant push notifications. Look for the video series BURNOUT that was both helpful and not locked.

Uninstalled after 4 days. I downloaded Flo in order to understand by body better and track my period, but didn't realize how pushy this app would be to try to make you pay for premium. You really don't have a lot of access to anything unless you upgrade, which is disappointing. Constantly getting pop ups to upgrade, and the chat bot kept popping up to chat (which you can't even use unless you upgrade). I had higher hopes. 🙁
