Data safety
arrow_forward
Safety starts with understanding how developers collect and share your data. Data privacy and security practices may vary based on your use, region and age. The developer provided this information and may update it over time.
This is a great app, with the major exception that this app really pushes the monthly or yearly subscription at every possible opportunity. If you don't want or can't afford the subscription, it's a real pain. I just want to track my cycle. It would be amazing if I could turn off the articles (most of which need a subscription to read). However, for tracking your period, this app is the best on the market (I've tried a fair number).

Great app for adults. There's a lot of explicit material that goes beyond simply educational content, so I wouldn't feel comfortable with my daughters using the app until they were much older. Also, even if you use the same log in, changing phones will cause all your data to disappear!!!! I was devastated to say the least when my app showed I was logged in but all my menstrual history was gone on my new phone. Be warned!

This app used to be fantastic. I used it for tracking my first 3 pregnancies and always recommended it to people. But that is not the case any longer. The only thing it shows now is how far along you are. Literally everything else is behind the paywall. It used to show you how big your baby was, where they are developmentally, and give you tips on what to expect. Now, anything you click on prompts you to pay for a subscription. It's ridiculous and I will be deleting the app.
