About H2O Flow
H2O Flow is a lightweight hydration companion that lives in your Chrome toolbar. It sends timed reminders to drink water, lets you log every sip, and tracks your progress toward a daily goal — without any accounts, servers, or subscriptions.
FEATURES
💧 Smart Reminders
Set a reminder interval (15 min – 4 hrs). H2O Flow fires a native browser notification with a gentle chime so you never forget to hydrate.
📊 Intake Tracking
Log drinks in one tap — 250 ml, 500 ml, or any custom amount. A visual ring on the Home tab shows how close you are to your daily goal.
