Great app. It would be better if it was possible to set ovulation by yourself. At the moment it is estimated automatically based on previous cycles. Sometimes it differs from the reality. If you set this date by yourself the program will define start of the new cycle more properly

I downloaded the app in September 2016. I just saw some blogger showing it in her video and decided to try myself, and got used to it. For the last couple of years, it’s been becoming worse - a lot of functions that used to be free became unavailable, unless paid for. The add became more and more pushy and pervasive. Then the app stopped working without vpn and it was the final straw. For several months, I had to use vpn each time I open the app, and I just got tired of it. Besides, this new app version doesn’t apply to my iOS, so I won’t be able to download it back anyway. And it’s for the best. Your app used to be good. Now it’s just a huge disappointment. I hope it’ll change, though. But I don’t want to be a part of it anymore.

Hi. We've received many reports from users in your region having trouble accessing Clue. This is due to internet restrictions. Clue is committed to equal access to knowledge for everyone, regardless of location. A VPN might solve the issue for now. Also, even if you have an older iOS version, you should be able to download and use an old version of Clue. I hope this helps to clear up any confusion.
loyal user of 5 years, finally deleting the app
tsgrsv
the update is horrendous and clearly not finished. and why would you cut off the support of ios 14? and why not let the user base know? you don't even have any features that would need a higher ios. thankfully Flo still supports me and my preferred version of ios. oh but i can't even transfer my data to finally switch the apps since you took that feature away. just like reminders, clue connect, analysis page etc, all with NO NOTICE. what period app do women on ur team even use since your own has been rendered useless for months now? y'all need new leadership, this is atrocious
