Works with Apple Watch & Apple Health

ZestyCoach integrates with Apple HealthKit to read your workouts, activity, and health data — so your coaching adapts to what your body is actually doing.

Built on Real Research

What the Research Actually Says

Every recommendation in ZestyCoach traces back to peer-reviewed research in exercise physiology and women's health. We're explicit about what the evidence actually supports — and what it doesn't.

Phase-Level Guidance
We use what the science supports — not day-level rules that aren't there yet
Privacy-First by Design
Your period data never leaves your phone. Ever.

Your Cycle, Your Training

Phase-Based Coaching
Menstrual cycle phases — ZestyCoach coaching adapts to each phase

ZestyCoach adapts your training and nutrition guidance to each phase of your cycle — based on what the research actually supports.

Train smarter. Fuel better. Every week.
