Best tracking App
vansheeee
I have been using clue for 6 years. The user interface of this app and little features to track your bodily functions are so great. Sometimes I plan my days ahead by looking at the projections in the app, it helps me to sync my menstrual cycle with my workout plans and other stuff. I will recommend every woman or man ( as it can help you to track your partner’s cycle as well ) to use clue and responsibly plan things!
The pushed ads are getting insane
Z2019Dahlia
Ive used Clue for years and its been my primary tracking app but the pushed ads to buy the premium version has increased to an insane amount! I understand everyone needs money and the creators deserve to be paid but oh my god the ad gets pushed to me after every move on the app. I am not pregnant, not intending to get pregnant and the basic version is ample for me to track my period. But even opening the app now is difficult because every single move is followed by BUY OUR FULL VERSION. I’ve had to move to a different period tracking app now because it’s annoying to use Clue.
