Really easy to use, everything is easily explained and logical. After using it just for two months it's predictions are right. I now even can see when period "symptoms" are beginning. So cheap too!! Recomended to my friends also!
Very high subscription price. You can't buy the app.

I am a feminist and would like to support the project. But 9 euros per month or 40 euros per year the cost of a subscription is a lot. I am an artist and I buy software without a subscription for 12-50 euros. And you put such a huge amount of money for a subscription. There are many similar free apps on the market. And yours can't compete to pay for a subscription.
Developer Response
Hi there, and thank you for the feedback! We price our services so that as many people as possible can use Clue, while still making enough money to sustain our company. We didn’t want to do things other period trackers might do—like sell your data or show you a bunch of ads. If you can afford to contribute to Clue Plus and our efforts to improve the lives of women and people with cycles, then you’re supporting those who cannot afford it. However, we do reassess - hope to be able to find a balance that suits you in the future!

I have been using Clue for two years now and I love it! Very good in predicting next cycle, learns from your previous data inputs. I have seen my friends use other apps but I wouldn’t trade it for the world. So easy to use and very accurate!
Horrible update
Mõtetu
The last update is really bad. I used this app for birth control tracking and now this feature is gone. I don’t get reminders to take my pill and last 3 days I have taken late, because of this. I have been your user since 2016 and it is sad to see that your app is no longer comfortable to use. I really hope you bring back birth control feature and reminders.
Developer Response
Thanks for reaching out. We deeply appreciate that you’ve been with us since 2016. And we feel you. We’re currently in the process of rebuilding our app and while we do this, some things will be temporarily offline. We realize this is frustrating for you and we’re very sorry for the interruption to your tracking experience. Please get in touch at support.helloclue.com/hc/en-us if you have more questions, and we’ll make sure to help you in whatever way we can. All the best, Natacha from Clue.
