Today we released the most radical Clue update yet: a beautiful redesign and more holistic approach to cycle tracking. Based on thousands of user comments AND the latest scientific research, we developed 23 new tracking categories in Clue for iOS users to track all elements of their health in relation to their cycle (they're coming soon on Android!). Clue's algorithm is also 10% more accurate for all users, reducing the error margin for period predictions by one day.

People who use Clue can discover more about their bodies and health by tracking other elements connected to the cycle: from skin and hair to energy levels, digestion to sleep. Each and every tracking category has scientific research to support a link between it and the menstrual cycle.

"We are excited and proud to be able to offer Clue users increased accuracy and to have had the opportunity to listen to feedback and respond to requests for more in-depth and wider-ranging tracking categories. By adding the option to track everything from exercise and weight, to overall wellbeing, including mental state, illness and digestion, we hope to empower women to feel even more in control of their cycle and to help users curate an increasingly in-depth and detailed medical record." -Ida Tin, CEO and Co-Founder of Clue

We also added categories for tracking types of illness and medication taken, including more birth control methods. Now you can track the pill, the patch, IUD, cervical ring and the injection. Additionally, users can now log results of ovulation and pregnancy tests and track their weight.

Widening the net of traditional tracking categories, Clue's new 'appointments' category gives users have the option to log medical visits, as well as note when they have been on vacation or even a hot date. Similarly, the 'party' category allows users to log alcohol and cigarette consumption, make note of when they have had a 'big night' and flag when they have woken-up with a hangover.

The categories are:

  • Bleeding
  • Collection Method
  • Craving
  • Digestion
  • Fluid
  • Hair
  • Pain
  • Skin
  • Stool

  • Weight
