Menstrual Cycle Tracking – Plan Training Around Your Cycle

Opt-in menstrual cycle tracking with predictions, symptom logging, and integration with your fitness timeline. Understand how your cycle affects training and recovery, and plan activities around your body's natural rhythms.

What This Feature Solves

Menstrual cycles affect energy levels, recovery capacity, and training performance, but most fitness apps ignore this connection. You might notice that some workouts feel harder at certain times, but it's difficult to identify patterns without tracking cycles alongside training data.

DelayedOnset™'s menstrual cycle tracking integrates cycle data directly into your unified timeline. Log cycles, track symptoms, get predictions, and see how cycle phases relate to workout performance, recovery needs, and overall training patterns.

This feature is opt-in and respectful. You control whether to enable it, and when enabled, cycle data appears on your timeline alongside workouts, nutrition, and recovery—giving you the context to understand your body's rhythms and plan training accordingly.
