*New Features for Clue Plus subscribers*
We've enhanced our Analysis feature, so now you'll get a personalized overview of your past cycle lengths and period lengths. You'll see whether your cycle is considered irregular or regular, possible reasons why this could be, and Clue will notify you when you might want to see a healthcare provider.
Clue already predicts your period, ovulation, and PMS, but what if you could see into the future for everything you track during your cycle? Now you can. Forecasts give you personalized notifications about what's coming up, based on anything you've tracked previously that has a cyclical pattern—from cramps, to chocolate cravings, to feeling energetic, to good hair days.
Ratings and Reviews
Love this app (and a suggestion)
I have used Clue for years and I love it! It has helped me learn about my cycle and take control of my healthcare needs in a way I’ve never experienced. The only suggestion I have is that I wish I could track pregnancy in it as well- as far as I know there is a pregnancy option but it basically shuts down projections and eliminates the data from that time in the analysis. I don’t want to track fetal development or anything like that but it would be great if I could track my symptoms and experiences associated with pregnancy without having to mark a cycle as inactive. I had a miscarriage last fall and as we have started trying to get pregnant again I have wished that data was more available so I could see patterns and trends on months when I was pregnant compared to months that I wasn’t. As it is, when you say a cycle is inactive it won’t show you what day you were suspected to have ovulated, etc. which would be really valuable in trying to conceive. I really do appreciate this app and the work you are doing on it- I just wish it could track additional information and normalize the pregnancy experience without skewing or losing data. Thank you!
Hi ! Thanks for your sweet feedback :) Please keep in touch. Let us know if there's anything we can do better and write us a message to firstname.lastname@example.org. With <3 from Berlin, Ana
I’ve tried a lot of different cycle-tracking apps and this is definitely my favorite!! However, I really wish that there was an option to indicate that you’re switching to a different brand of birth control! Also, I think it’s be nice if we had the option to arrange our days of the week according to the day of the week our pack starts on (so I start my packs on Thursday and I would like it if the weeks started on Thursdays for me). I think that would be nice, because when I went in to my gyno to switch birth control, she was interested in which week of my pack I was having the most issues and it’s really hard to tell if it’s set up like a traditional calendar. Lastly, there are a tonnnnn of options for tracking which I really love, but I know that one of the some women literally throw up for seemingly no reason at all (I, being one of them lol) and it’s be really nice to have that specifically! Because usually when this happens to me, I end up just saying I have the flu, but that’s not really accurate since there’s no fever!
Anyway, I know that’s a lot, lol, but I really do love this app and and definitely think it’s the best that’s out!
I suffer from Polycystic Ovary Syndrome and have a number of symptoms throughout my cycle which can seem random, but Clue helps me understand patterns and recognize anything out of the ordinary that I may need to discuss with my doctor. I also suffer from anxiety, and the tracker for emotions and motivations is so helpful. When I have a bad day and feel like my whole life is going badly I can look at the calendar and see how many days I've marked as "happy" days.
The other types of tracking are important to me for other reasons too. My mom died of ovarian cancer a year ago at a young age (early 40s) and I've since become worried about my health. My doctor told me that I should track my symptoms (i.e. any irregular pains) so I can have a peace of mind knowing that these problems are part of my regular cycle or something that needs to be checked.
The only thing I would suggest to the developers would be to incorporate a section to track regular, daily prescription medications. I currently use another app for this but if Clue could find out a way to add it on then it would just be unnecessary. Either way I love the app and it constantly is getting better.
