It's really good when you pay for subscription. Works seamlessly, easy to use. Once you stop paying, whatever you do you will be bombarded with pop ups asking you to subscribe. I stopped paying because I realised I don't read any of the articles they share and the free functions are enough for me. But now it's become frustrating to use.

Hey there, sorry to hear this disrupted your experience. We understand and have shared your feedback with the team. Clue Plus subscriptions keep Clue running. Becoming a sustainable, independent business is the best way to ensure Clue can remain the menstrual health resource we all need. All the best, Ilaria from Clue

I've been on subscription 1 year. Discontinued because I lost time looking for any kind of analysis. Lots of features but I have to look for it. On subscription, I lost my reminders first. Contacted the team, no help. Biggest disappointment is being offered help from Planned Parenthood. Why?! I'm in EU using EU app. Super overwhelming and aggressive push to subscribe pop-ups. Why?! Also, menstruation is not a dirty word!

Hey, we're sorry to hear the Clue app wasn’t what you expected, and that we didn't help you when you needed. Feel free to contact us again and refer to this review, we'd be happy to help. Also, feel free to let us know where we didn't use the word menstruation, so we can pass the feedback on to our relevant team. All the best, Ilaria from Clue

Recently Clue has been sending me useless stupid notifications like "knowledge is power", to nudge me to read the in-app articles (the text of which is so small by the way that they're super hard to read). There's no way to turn them off separately from the rest of the notifications! I checked the in-app notification settings, and these don't even show up! When I get a notification from Clue, I want it to be about my period coming soon or being late. NOTHING ELSE!
