The APP was updated and some functions are gone. I wrote an email to share my feedback. They explained to me the background and in the latest update, I found the functions are getting back as before. Thank you for listening to customers feedback and understand what our needs.You have a really great, accurate APP. I really enjoy using it ever since the first time I downloaded it.

I hate the updates
Sharonssw
I’ve been using this app for at least more than 5 years. And it is my one and only favourite app to track and record my periods. However, in recent year it has been so unstable to use. The app frequently asked me to sign-up or log-in whenever I need to use it while keeping the failure of my data input. It is REALLY ANNOYING when you just have to write things down casually but the app never allows you to do so.And also, even when I’m with good-connected internet, it always shows an error that with my poor interest environment the app cannot work at all. Very upsetting and unconvincing☹️
Bad user experience after update

The new User interface and GUI isn’t as straightforward as it used to be! I must click “save” before exiting the “day” that I’m tracking, resulting in saving each symptoms in each date tab. I like the previous version where I don’t have to go through the hassle. And also, I cannot click on the definitions of each symptoms as before, not sure where it went but it was more convenient when it was on the same page as the tracking UI, so I can make sure what each symptoms means!
