Wellness that moves with your cycle
Cycle Phase Tracking & Predictions
Period Buddy tracks your menstrual, follicular, ovulation, and luteal phases. It learns your cycle length over time and predicts upcoming phases so you can plan ahead for energy shifts, mood changes, and symptom patterns.
Phase-Based Nutrition Guidance

Exercise Adaptation by Cycle Phase
Period Buddy adjusts your workout intensity to match your cycle. High-intensity training during your follicular phase when energy peaks, and gentler movement like yoga and stretching during menstruation when your body needs recovery.

Log cramps, bloating, headaches, mood changes, and other symptoms. Period Buddy identifies patterns across your cycles and offers evidence-based relief strategies, from breathing exercises to dietary adjustments.
PMS and Mood Support

Frequently asked questions
How does Period Buddy track my cycle?
Period Buddy uses your logged period start dates and cycle length to calculate your menstrual, follicular, ovulation, and luteal phases. When connected to a wearable, it also uses body temperature trends and HRV shifts to detect phase transitions more accurately. Over time, it learns your unique cycle patterns for better predictions.
Does it adapt nutrition to my cycle phase?
Yes. Period Buddy provides phase-specific nutrition guidance. During menstruation, it emphasizes iron-rich and anti-inflammatory foods. During the follicular phase, it focuses on energy and protein.

Can I use it with my wearable data?
Absolutely. Period Buddy integrates with Garmin, Oura Ring, and Apple Watch. Wearable data — especially body temperature, HRV, and sleep patterns — helps Period Buddy detect cycle phase transitions, correlate symptoms with biomarkers, and provide more personalized recommendations. However, wearable connection is optional.
