Slurp

Slurp is a free water reminder for Mac and Windows. On a Mac it lives in the notch and menu bar, and on Windows it sits at the edge of the screen and in the tray. A small glass fills up as you drink.

When you fall behind, Slurp opens with your drink and amounts ready and waits for a natural pause, so it never interrupts a sentence. You can log water, tea, coffee, juice, milk or sparkling water with one click or a keyboard shortcut. Reminders hold off while your mic is on, while an app is full screen and outside your work hours.

It needs no account and works offline. The Mac version is under 4 MB and keeps its data in one small file on your Mac, while the Windows version is on the Microsoft Store for Windows 10 and 11. It suits anyone who wants a quiet nudge to drink more water through the day.
