Designed for women navigating preparation, early and late perimenopause, and postmenopause, it translates existing health data into practical daily guidance. Through Apple Health, anna reads more than 30 signals, including sleep, cycle, stress and heart-rate variability, from compatible devices such as Apple Watch, Garmin, Fitbit, Oura and Whoop, or from an iPhone alone. Each morning, the app offers one personalised, evidence-backed focus and explains the reasoning, with links to research sources.

Instead of symptom diaries, dashboards or endless feeds, anna provides a simple way to understand patterns and decide what to focus on that day. Its guidance draws on a library of more than 1,000 rules informed by over 300 studies and reviewed by clinicians. The app does not diagnose, treat or prescribe; it supports self-awareness and conversations with healthcare professionals. anna also offers educational articles and guides about perimenopause.
