AI running coach for any watch
Only for iPhone

iPhone
Your AI running coach with adaptive weekly plans, post-run audio analysis, and a coach that actually remembers what you ran last Tuesday.
RunNerd is your AI running coach. Connect any watch that syncs to Apple Health or intervals.icu — Apple Watch, Garmin, COROS, Polar, Wahoo, Suunto — and get personalized weekly training plans, post-run audio analysis, and a coach that knows your history.
WHAT IT DOES
• Adaptive weekly plans that learn from what you actually run, not what a generic template says you should
• Post-run audio coaching brief — listen to your analysis hands-free
• Mile-by-mile splits with HR zones, pace, elevation, and cadence
• Race-aware planning — set a goal race and your plan periodizes automatically
• Conversational coach for questions like "Why was my HR higher today?" or "What should tomorrow look like?"
PRIVACY-FIRST
• HealthKit data is read-only and processed only to generate your coaching content
• Sign in with Apple — no passwords, no tracking
• Not sold, not shared with advertisers
NOT MEDICAL ADVICE
RunNerd is not a medical device and does not provide medical advice. Always consult a healthcare professional before starting or changing an exercise program. Stop and seek medical care if you experience any concerning symptoms while running.
REQUIREMENTS

• Apple Watch recommended for in-workout heart rate
• Apple Health permissions for workouts, heart rate, and active energy
• Intervals.icu supported for linking non Apple Watch devices (Garmin, COROS, etc) - creating an account is easy and free
