About this app
Most people drink water. Few drink it right. Flux is the first hydration app built on circadian biology - the same neuroscience research discussed by leading scientists. It's not about drinking more. It's about drinking at the right time, in the right amount, for your body. HOW FLUX WORKS Your hydration needs aren't the same every hour of the day. Your brain, muscles, and metabolism follow a precise biological clock - and your water intake should too. Flux calculates your personalized daily target based on: - Body weight (ml/kg formula) - Your 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. Flux tells you when to drink before you get thirsty. Because by the time you feel thirsty, you're already 1-2% dehydrated - that's a 10-20% drop in physical performance and a measurable decline in cognitive function. - Circadian timing protocols, not random reminders - Personalized to your body weight, schedule, and lifestyle - Training adaptation, adjusts targets on workout days - Weather-aware, live temperature and humidity adjustments - Apple Health integration, automatic sync with your activity data - Dynamic Island and Live Activities, your hydration status always visible - Smart reminders, timed to your circadian window THE SCIENCE Flux is built on peer-reviewed research in hydration physiology and circadian biology. Our protocols reference published work from Stanford neuroscience research and leading hydration scientists including Dr. Samuel Cheuvront and Dr. Robert Kenefick. We don't invent protocols. We implement the ones that already work. FOR ATHLETES AND HIGH PERFORMERS Flux is built for people who take performance seriously - athletes, biohackers, founders, and anyone optimizing their mental and
