PeeTime is a results-driven hydration app that uses Apple Watch to automatically track urination. Understand whether your water intake truly benefits your body. We go beyond reminders and check-ins—PeeTime helps you see how your body responds after drinking. With insights into urination rhythms, uric acid, and ketone levels, plus clear weekly and monthly trend charts, PeeTime helps you hydrate with purpose. ◎ What PeeTime Can Do for You •Remind you when it’s been too long since your last urination—maybe your body is under load. •Spot signs of underhydration or stress through changes in urination patterns. •Track ketone levels to help evaluate fat-burning efficiency during a weight-loss plan. •Monitor uric acid trends and join health challenges to help reduce levels. •Turn your Apple Watch face into a health feedback dashboard—raise your wrist to see how your body’s doing. •Visualize hydration and urination data over time to better understand your body’s rhythm. ◎ Why We Built PeeTime We live in an age of metabolic chaos. Everyone is told to “drink more water,” but how do you know if it’s actually working? Instead of relying on timers or generic reminders, we asked: Why not let your body tell you when it needs water—and whether it appreciated it? So we built PeeTime—an app that listens to your body and gives real feedback. It’s not just about “drinking more,” but about drinking smarter, supported by your own physiological data. ◎ Our Philosophy There are already too many metrics in modern life—KPI, NPS, OKR… We didn’t want to turn health into another task. That’s why we designed PeeTime not to push numbers, but to offer emotional support through gentle design. Every interaction is meant to feel soft, empowering, and reassuring—not stressful or shame-driven. Whether you’re hydrating, detoxing, or simply trying to feel better—PeeTime meets you with calm clarity, not cold stats. ◎ Key Features •Automatic urination tracking via Apple Watch •Uric acid and ketone logging & trend analysis •Smart hydration challenges: Lower uric acid / Avoid sedentary life / Burn fat •Daily, weekly & monthly rhythm charts •Beautiful Apple Watch complications •Coming soon: iOS widgets, dynamic recommendations, hydration insights ◎ Contact Us We’d love your feedback and suggestions!
