P Water App

P is a hydration reminder app for iPhone and Apple Watch that uses bathroom-visit logs instead of asking you to record every glass of water. When you log a visit, the app builds a view of your timing and sends reminders based on your pattern, including the time since your last logged visit. This offers a lightweight way to notice hydration habits without measuring servings or setting a daily water target. Logging is designed to take only a few seconds and can be done from the phone, Apple Watch, a widget, or a watch-face complication. The app also provides streaks, calendar views, notes, and optional exports to help you review your history. Friends can send one another quick reminders, and optional location logging can associate visits with places. Apple Watch handwashing detection can help identify visits you may have forgotten to record. P also includes a Voiding Diary Mode for people who want a timestamped record of bathroom patterns, with optional volume and notes. The record can be reviewed or shared with a clinician, but the app is described as a general wellness product rather than a medical device. It may suit people who want simple hydration reminders, a low-effort habit log, or a personal record to discuss at an appointment.
