Ratings and Reviews
Let me start by saying I have been using this app for around 4 years now and I love it! But ever since it came out with the whole “premium membership” thing I miss some aspects that I used to have. I no longer receive emails basically as a summary of my last cycle and I used to look forward to receiving those, it helped me get a better understanding of my cycle. And I don’t know if that is a feature in the premium membership I just noticed that when the app came out with premium membership I stopped receiving those emails, and personally I think that’s something everyone should have the privilege of receiving premium membership or not. But i also wish the app was a little more descriptive with its data, or at least had more options. For exercising I wish it had more options, it only has things like running and swimming but what about those who weight lift or walk? There are other things I wish it had as well like dizziness or how much you ate in a day or anxiety/depression, some of these things may already be on there some of them may not but I still think it’s good to have them/look into more options to collect data for. Overall, this app is great with tracking my period I just wish it went a little more in depth and helped you understand what all of it meant like it used to.
Love it, but a suggestion
I really love clue, it’s a really easy place to keep track of everything related to my cycle.
One thing I would like to suggest is to allow us to choose if we want to log our flow (or other things) multiple times a day or just once like it is now. Personally I would love to be able to mark my flow each time I use the restroom/change my tampon/pad and have clue give me the average flow for that day. I just thought this would be a nice option since I know I sometimes have trouble deciding what I want to mark a whole days flow as (like if I’m light in the morning and night but heavy in the middle of the day).
Another part of this would be to be able to log the time (if you choose), like if I get my period at 11 pm (when I normally get it in the morning). I have a really hard time remembering when I got my period and most of the time if it starts later at night it’ll go an extra day long. So it would be nice to be able to see what time I got my period, and (if marking the time for each restroom break) over time you could be able to recognize patterns of your flow throughout each day of your period.
Just a couple of thoughts, but I love this app. Thanks in advance for reading my suggestions!
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!
