HydraShift

HydraShift is a mobile app (iOS/Android) that builds a realistic hydration schedule based on your routine, not generic “8 glasses” advice. You set wake/sleep times, work blocks, commute, workouts, caffeine/alcohol habits, climate, and bathroom access constraints (the part most apps ignore). The app then generates small, timed “sips” targets and adjusts dynamically when you miss doses, travel, or have a late workout. It integrates with Apple Health/Google Fit for activity and optionally pulls weather to adapt targets. The core is behavior design: fewer annoying reminders, smarter timing, and a “don’t punish me” catch-up mode that avoids overhydration. Monetization is a low-cost subscription for advanced schedules, integrations, and multi-profile support (e.g., athletes, pregnancy, elderly care). This is not a medical device—just practical habit coaching with guardrails.
