Stamina Bar

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.
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 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.
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.
