Flux: Hydration Science

Most people drink water. Few drink it right. Flux is the first hydration app built on circadian biology — timing your water intake to your body's biological clock, not just tracking how much you drank. It's not about drinking more. It's about drinking the right amount, at the right time, for your body. HOW FLUX WORKS Your hydration needs change hour by hour. Your brain, muscles, and metabolism follow a circadian rhythm — your water intake should follow it too. Flux calculates your personalized hydration timing protocol based on: Body weight (ml/kg formula) Wake and sleep times (circadian window) Training frequency and intensity Weather and ambient temperature Caffeine and alcohol intake Then it tells you exactly when and how much to drink — from your morning protocol (500ml within 30 minutes of waking) to your evening cutoff (2-3 hours before sleep). WHAT MAKES FLUX DIFFERENT Every other water tracker asks you to log drinks after the fact. Flux tells you when to drink before you're thirsty, because by the time you feel thirst, you're already 1-2% dehydrated. That's a 10-20%+ drop in physical performance and a measurable decline in focus. Circadian timing protocol, not random reminders Personalized to your body weight, schedule, and lifestyle Training adaptation who targets adjust automatically on workout days Weather-aware with live temperature and humidity adjustments Apple Health integration. Automatic sync with your activity data Dynamic Island and Live Activities where your is hydration status always visible Smart reminders timed to your circadian window THE SCIENCE Flux's protocols are built on peer-reviewed research in hydration physiology and circadian biology. We don't invent protocols — we implement the ones backed by published science. FOR ATHLETES AND HIGH PERFORMERS Flux is built for people who take performance seriously — athletes, biohackers, founders, and anyone optimizing their body and mind.
