Updated. I’ve received the respond from support department, and they help me with my problem. Do I want to give 5 stars. Previously: “It was really perfect woman app, but now I am confused about premium subscription, I haven’t read any additional articles for 2 years, I only fix all time my woman cycle details, and today I see “premium” status on my account, and I have not find the way to change it. “

Hi Jana2345! Thank you for your feedback! We’re very happy to assist you anytime :) Best regards, Flo Team
Some time ago I’ve just missed start of OC pills for 2 days after 7-day pause due to no notifications from the app received though they’ve been set up. And now the way of firing notifications is just changed by developers, so previously used option ‘Repeat until OC intake’ is not working anymore and it seems it disappeared from the app. Considering the fact the app is mostly updated in the background and no release notes are provided automatically to view for users - I just had no idea notifications won’t be sent until OC intake is logged to the app. My bad is lack of responsibility regarding my pills, but if I had enough responsibility I could not use app notifications at all. So very bad impression, sorry
