Stamina Bar is an innovative Apple Watch app designed to gamify health metrics, transforming complex data into a fun and intuitive experience. By visualizing your health as a dynamic stamina bar, this app empowers you to take control of your fitness journey and make smarter decisions about your wellness. The idea for Stamina Bar was born out of a personal challenge. While training for a 50-mile ultramarathon, I needed a way to better understand my recovery and exertion levels.

By combining insights from Apple Watch HealthKit data with cutting-edge AI, I built Stamina Bar to solve a real-world problem: making complex health metrics simple, actionable, and engaging. What started as a personal project has grown into a tool helping thousands of users worldwide take charge of their fitness.


Whether you’re a seasoned athlete or just beginning your path to a healthier lifestyle, Stamina Bar Pro helps you monitor, understand, and improve your health metrics with ease. Your health metrics, including Heart Rate Variability (HRV), VO2 Max, and more, are visualized as an easy-to-understand stamina bar.

Green/Blue Zones: Fully recovered and ready to perform at your best.
Yellow/Orange Zones: Moderate exertion; keep pushing or take a breather.
Red Zones: Overexertion—slow down to prevent burnout or injury.

Log your workouts and track progress directly from your Apple Watch. Use the app to optimize your training intensity, avoid overtraining, and achieve your fitness goals. Recognize the impact of stress on your body through your stamina bar. Engage in mindfulness exercises to improve HRV, reduce stress, and recharge your stamina levels. Designed with Accessibility in mind, Stamina Bar Pro supports VoiceOver, dynamic text, and easy one-arm navigation to ensure everyone can benefit from its features.

Stamina Bar is perfect for active individuals, from marathon runners and cyclists to professionals managing busy lifestyles. Its gamified interface makes tracking health metrics enjoyable, while its AI functionality offers personalized advice tailored to your unique needs. By combining health data, science-backed insights, and engaging design, the app empowers you to stay consistent without burning out. Unlike other fitness apps, Stamina Bar Pro is built on a foundation of simplicity and gamification. It translates complex data into actionable insights, motivating users to stay active and mindful of their health. Plus, its AI-driven approach offers unmatched guidance, making it a one-stop solution for fitness and wellness.
