Very good app for period and pregnancy tracking, but..
ficsorancsa
I use this app for tracking period and its wonderful! I also subscribed to the premium which gives a lot of extra content and things to track! Altough it is a great app there would be one more feature which would make this app even greater! Now you can choose between period tracking, conceiving, and pregnancy. But it would be great to have an option where you can track IVF pregnancy and the preparations. We just got to the point where we need IVF and it would be so helpful if I could follow every step in this app! The medications, the procedures, bloodworks etc. That would make it an even better app! Thank you!

It's OK

I used to love this app. It's still alright, I appreciate that you visibly keep adding improvements to this new version... However, I miss the ability to view patterns and repetitiveness in different symptoms (eg. to be able to see in which parts of the previous cycles I had breast tenderness etc.) and also, I don't like this new layout at tracking... I have to scroll waaay down for certain symptoms, and whenever I'm changing days it jumps to the beginning of the list... Sometimes I need to be able to quickly add the same symptom (that's at the end of the list) to multiple days and this makes it exhausting to track...

Hello, and thanks for your review. We have some nice updates regarding symptom visualization - please make sure to update the app to see them. Stay tuned for more updates and improvements to the tracking experience. All the best, Clue.
Quite good, suggest to download.

Quite good, suggest to download. 24/Feb/2019:Cannot read the details of the tiles becuase i cannot scroll down. It was worked earlier. I have re-installed the app but still not ok. Could you please check?————————————————-What should be improved is:- ‘spotting’ at Bleeding is not a useful tile. I think it would be worth to change this as I think more people have spotting bleeding during her cycle than ‘untipical bleeding outside of the cycle’. - pain: I’m missing the tile of weak limbs, debility, heat wave, etc. - there would be great if we can record unique observations. Like mention the texts in the ‘other’ tile.
disappointed with the new update
emlnra28
This used to be my favorite app but not anymore. I used to be able to see logged symptoms in the calendar view, now i have to manually search for each day. Much harder to compare symptoms. It also doesn’t display cycle days anymore so I have to count it. This kind of defeats the purpose of having an app as I can do these in a paper calendar just the same. Also, the stool feature changed, which just completely eliminated years of important data, that for me, as a person with crohn’s was invaluable. I don’t know if I can still access that data somehow but not sure if I want to log it all over again in a different app ever since 2018.
