A water tracker that fills up
Gulp's main screen shows today's water as a glass that fills up, with one-tap buttons for common drink sizes.
Gulp is built around a single screen. Your progress towards today's goal fills the screen with animated water, with quick-add buttons for 150, 250, 350 and 500 ml and a list of what you've drunk today.
The default goal is 2,000 ml.
