Liked the app, but then it no longer kept sending reminders for me to take my pill. That's basically the whole reason I downloaded. Uninstalled and reinstalled, changed the time, etc to troubleshoot. It will work fine for a couple days then stop again. I'll find another app. Edit: I decided to try the app again and I still have the same issue, years later, even though I've opened the app every day this week and have made sure notifications are allowed. Definitely a problem on Clue's end.

I've tried other apps for this situation and prefer Clue. Extremely user friendly. As I'm entering menopause this has been a great tool to monitor the changes in my cycle. I started using the app when you could set a clock to me. It was super helpful to be able to track symptoms so I could prepare accordingly.

I've been using Clue for (could it be?) a decade now. I remember how revolutionary the app's visualization of the cycle felt to me as a young woman. I love and trust Clue, their tracking options are plenty and their predictions are useful even through times of hormonal imbalance. I particularly like their educational content and how it's not the usual catastrophizing type of health content, it's quite informative and not too scary. Overall, 10/10.
