# WaterChamp — Water, Caffeine & Alcohol Tracker for iPhone WaterChamp is a hydration tracker for iPhone with smart tracking for water, caffeine, and alcohol, fronted by "Champ", a water-drop mascot who reacts to how your day is going. - **Website:** https://waterchamp.app/ - **Platform:** iPhone, iOS 16.2 or later - **Price:** Free, with an optional Pro subscription - **Availability:** Launching soon on the App Store - **Contact:** support@waterchamp.app ## What WaterChamp does ### Log any drink in seconds 59 built-in beverages, from water and coffee to smoothies and cocktails. Each drink is logged with realistic nutritional data including calories, caffeine, alcohol, and hydration value (wine counts for half a glass of water; spirits count for none). Supports dose-based logging (e.g. espresso shots instead of milliliters), favorites, and search. The daily goal is calculated from your weight, activity level, and climate. ### Last chance for coffee (signature feature) WaterChamp models the caffeine in your bloodstream in real time, based on published pharmacokinetics. A live chart shows your caffeine curve with a projection to bedtime, a sleep-safe time, and the latest time you can drink a coffee and still sleep well. Includes a daily caffeine budget. ### Real-time hydration level Hydration is modeled as a live level that rises when you drink and decays through the day, not just a daily counter. The app projects it forward ("thirsty by 21:00") and reminds you before you get thirsty. ### Alcohol & BAC tracking Logs alcoholic drinks with a live blood alcohol estimate and a sober-by projection. ### Streaks, calendar & achievements Every goal day fills a water drop in a monthly calendar. Streak tracking, daily check-ins that reward drinking regularly through the day, day recap cards, lifetime stats, weekly trends, and hand-drawn achievement medals (First Drop, Week Warrior, Early Bird, Goal Getter, Steady Sipper, Hydration Hero, Night Owl, Gallon Club, and more). ### Widgets Home screen and lock screen widgets keep the daily goal visible. ### Apple Health integration With permission, WaterChamp writes water, caffeine and alcohol to Apple Health, and reads workouts, active energy and sleep to adjust the daily hydration goal on active days. ### Apple Watch (coming soon) An Apple Watch companion app is planned after launch: log drinks and check progress from the wrist. ### The Champ mascot A hand-drawn water-drop character with dozens of moods reacts to your hydration state: celebrating when you hit your goal, thirsty and droopy when you're behind, jittery and coffee-brown after too much caffeine. The app uses a warm pastel design. ## Pricing - **Free:** drink logging, hydration goals, caffeine and alcohol tracking, streaks, calendar, widgets, Apple Health sync, achievements. - **WaterChamp Pro (subscription):** future projections, full history, Pro stickers, backdated logging, and custom drinks. ## Privacy All hydration data is stored locally on the device.
