Hands down the best app to keep a track of not just your reproductive health but overall health. One just needs to put it to use fully. It helps you keep a track of all the things that might add up to any possible reproductive health condition or anything otherwise. Have been using it for 4 years straight and it just keeps getting better and better. It makes my gynaec happy too as she’s able to get a proper diagnosis of what’s been up with my body all the while. I always always always keep it at handy. Plus the article that you read on the app are actually genuine and help you better understand and make a mini diagnosis of whatever you’re going through before you see a doctor because trust me a women’s body never stays the same.

I’ve been using this period and pregnancy app for a while now, and I couldn’t be happier! It’s incredibly intuitive and has been a huge help in tracking my cycles, understanding my body better, and planning for the future. The predictions have been accurate, and I appreciate the detailed insights it provides about each phase of my cycle.The pregnancy tracking feature is equally amazing, with weekly updates that give useful, encouraging information about what to expect. Plus, the app has a supportive, non-judgmental tone, which makes the whole experience feel personal and positive. I highly recommend this app for anyone looking to track their cycle or their pregnancy journey with ease!

I m using this app since last 10-12years. And it has always showed me the right information. App has always helped me to track and monitor all my cycles and predictions with terms of periods and pregnancy both. Whatever the daily predictions shows it was a day here and there but bingo it is true. During my entire pregnancy I really enjoyed weekly fetus updates. I used to see the images and feel my baby ☺️. Thank you Flo for always helping me to be connected with myself, it would not be possible without you. I can’t even imagine to switch to any other app as I am so used to it. I can say you should give me lifetime free subscriptions 😜
