Your body isn't a bucket — it’s a river. Standard water trackers treat hydration like a static container you fill up until you hit a random number. Sip changes the game by treating your hydration like a metabolic battery that naturally drains throughout the day. Using our proprietary decay algorithm, Sip visualizes your body’s real-time fluid status, giving you an accurate, science-backed view of when you actually need to drink. Why choose Sip? METABOLIC DECAY TRACKING Most apps ignore that your body processes and loses water continuously. Sip accounts for this, showing you a living hydration level that provides a realistic picture of your health. No more false sense of security after a single morning glass—Sip shows you the truth. ADAPTIVE GOALS Your water needs change daily. Sip connects securely to Apple Health and WeatherKit to automatically adjust your daily intake requirements.
