BetterRunning
BetterRunning is an AI-powered running coach application designed exclusively for Apple Watch and iPhone. It leverages health data from Apple HealthKit—such as heart rate variability (HRV), sleep duration, and training load—to create highly personalized and adaptive training plans. Unlike static, template-based running schedules, BetterRunning reads your recent run history, analyses your fitness level, and builds a periodized plan that evolves with every completed workout. Each morning, the app generates a daily readiness score by combining overnight recovery metrics. Based on this score, it automatically adjusts the day's planned session—scaling intensity down on low-recovery days or confirming hard workouts when you're fresh. This ensures that training is always aligned with your body's actual state, reducing injury risk and optimising performance gains. The Apple Watch companion app provides on-the-go coaching without needing a phone. It displays real-time pace, heart rate, and interval phase tracking, and offers haptic cues for phase transitions. Post-run, you receive detailed feedback that compares your execution against the plan, contextualised by your sleep and recovery metrics. All personal health data is processed on-device, prioritising privacy. BetterRunning supports a wide range of running goals, from 5K to marathon distances, with plans that scale weekly volume appropriately. Its pace zones are recalibrated after each run using actual performance data rather than generic formulas, meaning the coach becomes more accurate over time. The onboarding is seamless: simply set a goal, and the AI instantly generates a full training calendar tailored to your history and timeline.

Problem solved
Most running apps provide generic, static training plans that ignore daily fluctuations in recovery and fitness. BetterRunning solves this by using Apple Watch health data to build and continuously adapt a personalised running plan that respects the user's daily readiness, injury risk, and actual performance, leading to safer and more effective training.
