Hydrate makes drinking enough water one tap. It tells you what's left today in plain words, logs a glass, can or bottle without typing, and keeps your streak going. No account, no subscription, nothing to set up beyond your goal. Today • What's left, up top: "24 oz to go", then "Goal reached". • A goal ring that fills as you drink. • One tap for a glass, can, bottle or large bottle, in ounces or milliliters. • Any other amount at any time, for the drink you forgot to log. • Change or delete any drink, on any day. History • Your daily average, goal days, streak and personal best for the last week or month. • A bar for every day, and every day's drinks to look back on or put right. Apple Watch • Log a drink from your wrist and see what's left today. • Complications for your watch face. • Drinks logged on your Watch reach your iPhone, even if it was out of reach for a while. Widgets • Home Screen and Lock Screen widgets show what's left at a glance. Reminders • Reminders every one to four hours, between the hours you choose. • Each one says what's left, and they stop for the day once you reach your goal. • Log a glass straight from the reminder. Apple Health • Connect Apple Health and every drink you log is saved there as Water. • Delete a drink in Hydrate and it's deleted from Apple Health too. • Hydrate only saves Water. It doesn't read anything from Apple Health. Make it yours • Eight accents, each with its own app icon. • Light, or one of two darks: soft Graphite or true Black. Private by design • Your drinks stay on your device. No accounts, analytics, ads or tracking. Hydrate helps you build a daily habit. It isn't medical advice; ask your doctor how much water is right for you.
