Water Tracker
Read full descriptionHide full description
Meet the goose. It watches you drink water. It is not impressed. It logs anyway. Water Goose is a hydration tracker with a face and an attitude. Pick a drink, pick an amount, save. The ring fills, the goose says something dry, and you get on with your day. No confetti, no guilt trip, no motivational performance. Browsing is free. Saving drinks, editing history and changing your goal, reminders, units or quick-add amounts need Water Goose Plus - $3.99/month or $9.99 once. WHAT THE GOOSE DOES (SAVING AND CUSTOMIZING NEED PLUS) - Logs a drink in three taps: pick the type, pick the amount, save. Today, or back-date one you forgot. - Quick-add buttons for the amounts you actually pour. They start at 250 / 350 / 500 mL and you can set them to whatever your glass holds. - A daily goal you choose yourself, in milliliters or fluid ounces - or no goal at all, if goals are not your thing. - Optional water reminders: pick the hours and a nudge every 2, 3 or 4 hours. Off until you switch them on. - A calendar of every day so far. Tap any date to read it back, fix a mistyped amount, or delete the third coffee. - Quiet stats above it: 7-day average, goals met this week, and a day streak you are free to ignore. - Four illustrated hydration guides: "Small sips beat catch-up", "Yes, coffee counts", "Eat your water" and "Sweat changed the math". Short, practical and free of statistics. - System, light or dark appearance. - A goose that reacts to your progress in complete sentences. "Goal reached. Obviously." ALL 13 DRINKS IN ONE UNLOCK - NO PER-DRINK UPSELL Water, sparkling water, coffee, tea, juice, smoothie, milk, soda, soup, coconut water, sports drink, lemonade and energy drink. Every one illustrated. Coffee is a drink. It counts here. YOUR HISTORY, NOT YOUR REPORT CARD Your history is a water diary, not a scoreboard. History keeps the facts. The goose keeps the attitude. Log a drink, or do not. Water Goose will be exactly where you left it, saying nothing unless you asked for reminders. QUIET BY DESIGN - No ads. Nothing interrupts a log, ever. - No account, no sign-up, no email, no password to forget. - Your drinks, goal and settings are stored on your iPhone. There is no account and nothing to sync, so once you are set up, logging works with or without a connection. The questions at the start - gender, age, height and weight - are used once, on your device, to suggest a starting daily goal. It is a general-wellness starting point, not a prescription. It stays on your iPhone, and you can replace the number in setup. SO THERE ARE NO SURPRISES Reminders are local notifications, scheduled on your iPhone and sent only if you switch them on. Water Goose has no Apple Health connection, no widget, no Apple Watch app, no sync or backup, no data export and no iPad version. Made for iPhone, deliberately. A NOTE ON HYDRATION Water Goose is a general-wellness app. It is not a medical device and it is not medical advice. Hydration needs vary, so follow your own medical advice, especially if a health condition or medicine affects your fluids. The goose is an illustration, not a doctor.
