Why Sip Water Buddy?
Reminders you can't ignore
Characters stay on screen until you answer: Done, +10 min, +1 hour or Skip.
Water and anything else
Set your interval and daily goal, or add one-time, daily, weekly or every-N-minutes reminders.
Your hero, your pet
Name them, pick their looks, or bring your own 3D avatar and pet (.glb) and sounds.
Wait where you want
Click a spot on your screen and they wait there. Hover over them and they stop. Choose how long they linger after you answer.
To-dos with deadlines
Optional deadlines, reminders before they are due, and your list held by the hero and pet on the desktop. Drag them anywhere.
To-dos and 30-day stats
Keep a quick to-do list from the tray, and see glasses, goal deviation and skipped time for the last 30 days.
Multi-monitor
The characters walk across all your screens, and play fetch when you click.
Private by design
No network, no telemetry, no account. Everything stays on your computer.
Light and dark themes
A real Settings window with keyboard access and a tray icon near your clock.
