Tips for Staying Hydrated

Build the Habit

  • Keep a water bottle visible on your desk
  • Drink water before each meal
  • Use the quick-add buttons regularly

Monitor Your Progress

  • Check the water card throughout the day

Listen to Your Body

💧 Hydration Tip

If you forget to log water immediately, you can always add it later by tapping "Details" and manually entering the amount with the time you consumed it. Accuracy matters more than real-time logging!
