Evaluation of Smartphone Menstrual Cycle Tracking Applications Using an Adapted APPLICATIONS Scoring System

Area of Science:

• Digital Health
• Reproductive Health Technology
• Mobile Health Applications

Background:

• Smartphone applications for menstrual cycle tracking are increasingly popular among patients.
• Evaluating the accuracy and functionality of these digital health tools is crucial for patient safety and effective use.

Purpose of the Study:

• To systematically identify and assess the accuracy, features, and functionality of free smartphone menstrual cycle tracking applications.
• To provide healthcare providers with a list of accurate apps and key evaluation components.

Main Methods:

• Systematic search of the Apple iTunes store for free menstrual cycle tracking apps.
• Defined accuracy criteria based on cycle length, ovulation prediction, and absence of misinformation.
• Modified the APPLICATIONS Scoring System to evaluate features and functionality of accurate apps.

Main Results:

• 1,116 apps were initially identified, with 20 meeting accuracy and inclusion criteria.
• Accurate apps commonly included features like password protection, offline use, no ads, technical support, and tracking of flow, symptoms, and intercourse.
• Fertility medication support, professional involvement, and cited literature were rare in accurate apps.

Conclusions:

• The majority of free menstrual cycle tracking apps lack accuracy and scientific rigor.
• Accurate apps offer valuable features for conception, contraception, and cycle monitoring.
• Healthcare providers can use identified accurate apps and evaluation criteria to guide patient recommendations.
