Ratings and reviews

I have been using this app for five years. It used to work perfectly. Lately, the new changes made it harder to use (double confirmation needed). What's worse, it is now very unstable, constant white or black screens, I am essentially locked out of the app. I have waited for several months for an improvement regarding the bugs, today was the final straw. So long, Clue 👋

I've been using the app since I've had a smartphone. It used to be a great, free and good-loocking tracking app... Now it's still a good-looking app which is still great if you only need to track basic info about your period. You need to pay if you want anything more. Even health info about your cycles... It's a shame. Also, I need to change my email address but it doesn't work. I'm for the first time in years considering of changing for a new app.

Used to be good. I've had clue for almost 4 years, I used to recommend the app but it's sad to see the state of it it today. It is good because you can make an account so you don't loose data. However I uninstalled due to the amount of ads anytime you click somewhere, plus there are no more notifications to warn me when my period is coming. Half of the features that used to be available you now have to pay for... Don't waste your time with this app unless they go back to how it was
