The app
Hydration you can feel, one glass at a time.
Tap a glass and watch a real body of water rise toward the day's goal. An optional coffee-toned second page tracks caffeine beside it and pairs it with your sleep, so you can see what the afternoon flat white actually costs.
Not every drink hydrates equally, so each carries its own hydration factor: coffee, juice and alcohol count for less. Behind it sits a catalogue of roughly 1,880 real menu drinks across about 35 brands.
