The app itself is decent, and its user interface is reasonably friendly to access. Some basic information is locked behind premium, but it's not unreasonable, and the tracker works for free just fine. They just unrolled "Flo for couples." My partner uses Flo to track her period as well, and I was extremely disappointed in learning that the app does not support couples where both people have periods. Until Flo updates to be inclusive of all relationships, I can only give 2 stars.

I don't have the premium subscription, so I'm not sure if this is an option on that, but I would like it if when you select cramps for any symptoms, you could pick on a scale how bad they were. A bit annoying that when you have just started it doesn't provide lots of data about when your next cycle is. Other than that, overall good app, I will continue to use it. I think more articles and important information about things related to your cycle should be available to read without premium though.

Pros: Lots of good options for symptoms and, feelings, etc. Good articles and information. Cons: Dark settings have been removed. It makes it too easy for other people to look over and see what is on my screen. Please bring them back. Program updates have made Flo too geared towards pregnancy and trying to get pregnant. An option to turn those settings off would be preferable. Things which are meh for me: Group chat feature is interesting, but too many users are giving incorrect advice.
