The app that helps you stay hydrated all day long

Stay Hydrated All Day!

Aqueous is a beautiful, medically researched, water tracker for your iPhone and iPad. The app uses appropriate reminders to suggest the correct amount of water you should drink every day to help you stay hydrated.

Best of all, we donate 70% of any in-app purchases to charities who provide clean & safe drinking water to children around the world.

How Much Water Should I Drink?

Forget about the myth of drinking 8 glasses of water a day...
