About H2O: Water Tracker
Most water apps give you the same goal every day. H2O raises yours on hot days and after workouts, so you drink what your body actually needs. Log a glass in one tap from your iPhone, Apple Watch or Home Screen, and watch your streak grow on the calendar. H2O makes staying hydrated the easiest habit you'll build. H2O has helped people stay hydrated since 2016, and version 2.0 is rebuilt from the ground up. FEATURES ◉ Daily goals that adapt to the local weather and your workouts in Apple Health. ◉ Quickly add entries with preset water amounts, or enter a custom amount. ◉ An Apple Watch app with complications for your watch face. ◉ Home Screen widgets that log water with one tap. ◉ Gentle reminders to drink throughout the day. ◉ A calendar that shows every day you hit your goal. ◉ Charts of your weekly and monthly water intake. ◉ A full history of water entries. ◉ Apple Health integration and iCloud sync across your devices. ◉ Export your water history as a PDF. ◉ Track in ounces or milliliters. ◉ Support for VoiceOver, Voice Control, Larger Text and Reduced Motion. ◉ A beautiful and intuitive interface!
