I've been using Flo for over 4 years now, and have recently purchased the premium version. I honestly haven't used much of the functions, and don't track anything else besides my period. I think it's enough, but it's a great app. My only suggestion is that I'd like Flo to be able to synchronize to Samsung Health and/or Fit (Google's health app). | Update: I hope you'd add better widgets for our home screen.

It is useful for tracking but it has a pop up for premium and it has a pop up for someone to chat with you every single time I get on. It also has constant annoying notifications about random stuff that are not helpful. I wish it would notify me only when my period is about to start. I will be switching to a different app to see if it provides a more minimalist experience.

I've been using this app for years now and it is adequate. I could do without the popups to subscribe to premium, but those aren't as annoying as the notifications. I have every single reminder/notification turned off except for a nightly OC reminder, yet I a find myself getting 2-3 other notifications a day from this app and I cannot figure how to turn it off. If there could be an option to turn off all the other reminders and notifications that this app would be that much better.
