Ulla is the world’s first hydration reminder attachment that clips effortlessly onto any water bottle, helping you drink more water, feel energized, and avoid dehydration-related headaches—without an app or button push.
Why Ulla Stands Out
-
Universal compatibility: Fits bottles of any shape, size, or material.
- Simple yet effective alerts: Blinks subtly if you haven’t had a sip, reminding you to hydrate.
- Fully automated convenience: Turns on and off intelligently using light, motion, and proximity sensors—no charging needed.
- Long battery life: A single CR2032 button-cell powers Ulla for up to six months.
- Health-conscious design: Made from BPA-free polypropylene, it’s lightweight (28 g), compact (4 × 2.5 × 1 cm), and durable in temperatures from 0 °C to 70 °C.
Your Personal Hydration Coach
Ulla isn’t just a gadget—it’s a subtle coach that integrates health into your routine. By prompting you to drink regularly:

You may experience fewer headaches.

Your metabolism and skin health can improve.
-
You’ll sustain higher energy and concentration throughout the day.
Built for All Lifestyles
Whether at your desk, during workouts, or on the go, Ulla adjusts to your rhythm. The motion sensor detects sips, resetting the reminder timer. The light sensor ensures the blinking stays visible without being disruptive.
