Worst ads I've ever seen on an app. If you want to look through your period data, you get an advert between looking at every single entry. You get adverts while browsing through settings! The adverts are all video adverts, and about 90% of the time, there's no option to close them at the end. I absolutely understand the need to make money, but they're really, really excessive to the point that despite the app being otherwise really amazing, I would suggest not using it until this is resolved.

Hello, Elena! Thank you for your feedback. Ads help our developers keep the app up to date. You can also remove ads in settings. We are aware of the issue with the duration and frequency of the ads and are working to reduce them. Hope you can give the app a try once the issue is resolved. Best regards, Liza

Overall, the app is accurate with my period predictions. It has cute wallpapers and you can note down what happened each day. For example, your emotions and symptoms. I also really like how you can see the statistics of each period. One thing I would say to change is to make the colours different on the calender for each time your flow is heavier or lighter.

It's so amazing, I can see when my period should start and end. I can log my hormones that day and my moods! There are loads of cute themes too. If you have been a bit stressed there is a 1 minute breathing meditation you can do. You can also pick a time that works best for the app to remind you to log your period. Some ads but not much of a bother. 100% recommend, LOVE IT!
