A water reminder that lives in your calendar
10am, 1pm and 4pm, wherever you are. Each check-in takes two seconds to read and carries a short, practical hydration tip, not a guilt trip.

Most people don't skip water on purpose. They just forget until 3pm. This calendar adds three quiet check-ins to your day in your local time zone, so they move with you when you travel.
There's no single magic number of glasses. The U.S. National Academies put adequate total water intake at about 3.7 litres a day for men and 2.7 litres for women, and that includes water from food and other drinks. Needs rise with heat, exercise, pregnancy and illness. If you have a heart or kidney condition, follow your clinician's advice.
Dropkin: Water Reminder: One-tap water tracker and reminder built around the bottle you carry; ounces or liters.

Questions
Will it make my phone buzz?
Subscribed calendars on iPhone don't send alerts by default. To get a buzz, go to Settings › Apps › Calendar, find the subscription and turn off 'Remove Alerts', or set a default alert time. Many people prefer to just see the events on their widget.
Can I change the times?
A shared calendar can't be edited per person. If you want your own times and to log what you drink, Dropkin does that, built around the bottle you carry.
Is 8 glasses a day right?
It's a rule of thumb, not a scientific target. The National Academies figures above are a better reference, and your thirst and urine colour are useful day-to-day signals.
Is this calendar free?
Yes. It costs nothing, needs no account and shows no ads. You can unsubscribe at any time.
How do I remove it from my iPhone?
Open the Calendar app, tap Calendars at the bottom, tap the ⓘ next to this calendar and choose Delete Calendar. Or go to Settings › Apps › Calendar › Calendar Accounts › Subscribed Calendars.
