BioState

Track Your Fast. Visualize Your Biology. BioState is more than a stopwatch—it’s a metabolic compass. While other apps just count down the minutes, BioState uses your fasting data to visualize exactly what is happening inside your body. Built for biohackers, intermittent fasters, and those seeking cellular health, BioState bridges the gap between effort and biological insight. THE FIVE METABOLIC STAGES Understand the science of your fast. BioState tracks your progression through five distinct biological phases based on your elapsed time: • Anabolic (0-4h): Your body processes your last meal. • Catabolic (4-16h): Transitioning from glucose to fat-burning. • Ketosis (16-24h): Fat-burning is fully initiated as primary fuel. • Autophagy (24-72h): Cellular "cleanup" and regeneration begins. • Deep Reset (72h+): Maximum immune system and hormonal reset. ENGINEERED FOR THE MODERN iPHONE Get the data you need without ever unlocking your phone. BioState utilizes the latest iOS technology to keep you informed: • Live Activities: See your active timer and current metabolic stage on your Lock Screen. • Dynamic Island: Monitor your progress at a glance while using other apps. • Home Screen Widgets: Beautifully designed widgets to keep your goals front-and-center. THE "TIME MACHINE" EDITOR Life happens. If you forgot to start your timer, our intuitive "Time Machine" feature allows you to retroactively edit your start time. Your history and metabolic data stay 100% accurate, no matter when you remembered to tap "Start." PRIVACY & SIMPLICITY Your health data is personal. • No accounts or logins required. • No tracking or personal data collection. • 100% On-Device: Your data never leaves your iPhone.
