Clue was named the top free menstrual tracking app in a [study released this week by the journal Obstetrics & Gynecology, a publication of the American College of Obstetricians and Gynecologists (ACOG).

The paper, “Evaluation of Smartphone Menstrual Cycle Tracking Applications Using an Adapted APPLICATIONS Scoring System” was published May 9 by Professor Paula Castaño and team*.*

The study scored apps based on accuracy, features and functionality. Clue earned 13 out of 15 possible points based on a survey of 25 different features, the highest score of all apps evaluated.

Castaño and colleagues found that most menstrual tracking apps are inaccurate and only 20 out of more than 1,000 apps met accuracy criteria. Here is the final ranking:

  1. Clue
  2. Glow
  3. Pink Pad Period & Fertility Tracker Pro
  4. GP Apps; Period Tracker, Free Menstrual Calendar
  5. iPeriod Period Tracker Free; LoveCycles Menstrual, Ovulation & Period Tracker; Mom and Baby to Be
  6. Groove; Lily; Menstrual Calendar; Period Tracker
  7. Day After; MonthPal (now known as “Touchable Period Tracker”)
  8. Menstruation & Ovulation (now known as “Menstrual Period Tracker”)
  9. FemCal Lite; The Flow
  10. It’s a Girl Thing
  11. Fertility Cycle
  12. Free Girl Cal

Something to consider: This study looked at our iOS 1.9.1 version about a year ago, which isn’t as advanced as our latest update.

“Our community of over 4 million active users trusts Clue to provide them with reliable predictions about their bodies, which is why accuracy has been crucial for the app since Day 1. It’s gratifying to see the medical community recognizing the effort we put into providing our users with science-based, actionable personal insights into female health.” -Ida Tin, CEO and Co-Founder of Clue
