I use it for couple years and is still basically the only app that I let the notifications on and that it does not annoy me when i get notifications, aaaand that I actually open it everytime when i get them. Very useful, very knowledgeable, perfect app for the purpose it has. Should win awards. Good job Flo team!!

Do not update!

I have been using Flo since 2017 and I LOVED it! Nice clean interface, easy to use, transparent and user friendly - good things only...I haven't updated it for a while and today I thought I should push the update button. BIGGEST MISTAKE ever. The app is full of ads, pop ups asking to buy premium version...Dark theme has black wallpaper and bold pinky circles for period days. It's just painful and nasty to watch. It used to be so pleasing. You had a few background options and themes to choose from in the old version. Symptom trackers got visually worse - small and hard to find the right one. Too many things happening on the screen at the same time - chats, articles, adds etc - they are forcing them too much. Half of my screen is just not usefull or even distracting all the time. I'm really sad I did an update and I would love to go back to an older version if it would be possible. Sadly I will 100% start using some other period tracker and delete this one. It was nice while it lasted. Sorry Flo, but you got bad. At least for me.

Too many notifications
ana.j.m
It used to be really good, until recently. You get daily “new content” notifications, that are in my opinion useless. There is no way to turn them off without turning off the reminders you can get a few days before your period starts. You can’t have both. You want daily notifications gone? Turn off notifications for the app in your phone settings altogether. Bye bye period reminders. I was dealing with the intrusive “upgrade to pro” popups, although they were incredibly annoying, but this is the last straw. I’m going to switch to a different app. If you add proper notification settings in app, i would consider coming back.
Developer Response

We send notifications so that our users can learn about new features and insights in the app. At the moment, it’s indeed possible to disable the notifications by turning them off in your phone settings.

Have been using this app for almost 8 years now, everything you write down is remembered, it stays in the app even if you change your phone. The predictions are also very accurate to what's happening to your body.
