About
Hydro reminds you to drink and counts what you drank. Pick your cups once, tap one each time you drink, and the day fills up.
There is no account. Your water stays on your iPhone. Anonymous usage statistics go to the developer's own server. A random ID is added only if you turn it on, and you can turn it off any time.
ONE TAP PER CUP
• Up to three cups on the Today screen, in the sizes you really use
• Your daily goal, how far you are, and a small celebration when you reach it
• Milliliters, US or UK ounces
REMINDERS THAT KNOW WHEN TO STOP
• Choose a start time, an end time and an interval
• Add a cup straight from the notification
• Reminders stop for the day once you reach your goal
AT A GLANCE
• A Home Screen widget with today's water and your cups
• A Live Activity on the Lock Screen between your start and end time
• Light and dark themes
• A gently moving water surface, which follows Reduce Motion
