I think I’ve been using this app since... 2014? Still the best one: clear, nice stylish design, all info I need (and I don’t need much), and OK even if I do not plan have kids. I mean most apps seems to be over concentrated around the ovulation. Well it’s a long topic :) Thanks to all creators! You did exactly what’s needed.

The app is great, but I keep missing pill reminders

I have been using another pill tracking app for years, but since the new iOS 11, the other one is not compatible anymore. So since I have been a Clue user for several months now, I figured I should just migrate the tracking completely to Clue. But since daylight savings time change, I keep missing notifications despite them being turned on for all this time. This is very confusing and I keep missing my time since I remember to take the pill much later than scheduled. Please fix this problem. Otherwise the app works great.

I’ve been using this app for 10 years and when I decided to try to conceive unfortunately I found zero info or user support around that topic. On contrast, ux and all the app texts written like they are kinda against pregnancy. Yes, choice is important, but pregnancy is also a huge part of women experience. We can’t delete that from our lives because of political trends. Sorry to leave you guys for Flo and thanks for these years!

Developer Response
Hey, thanks for your review. We’re sorry to hear the Clue app wasn’t what you expected. The app has a specific function for those who want to conceive, called Clue Conceive, and it also has a pregnancy mode. We always want to improve, so we’d love to hear more feedback from you. If you’re interested in telling us more, you can reach us at support.helloclue.com/hc/en-us. All the best, Ilaria - Support Team
