Ulla Smart Hydration Reminder

Simply attach Ulla to your bottle - it knows when you drink and blinks when you forget to.
Attach Ulla
​Ulla works with bottles of any shape, size and material.
Get a friendly reminder
​Ulla starts blinking every time you forget to drink water for too long.
Feel better, feel great 
​Forget about headaches, fatigue, constipation, depleted immune systems ... gone.
The number 1 reason why you're not drinking a full 8 glasses a day. Because Even after getting yourself a bottle, water is still the last thing on your mind.
Discrete yet effective
​
Ulla’s effective blinking alert, developed by the US Navy, ensures you’ll always notice Ulla no matter how busy or distracted.
Optimal hydration intervals
​
​Ulla reminds you throughout the day to hydrate every 40 minutes – but only if you forget to drink. Good drinking habits, no blinking – simple.
Auto ON/OFF

Ulla wakes up when you enter the room in the morning, and goes quietly to sleep when you turn the lights off for the night.
Smart drinking detection
​
A high-precision accelerometer always knows when you take a drink. So Ulla knows only to blink when you forget to hydrate regularly.
Fits any bottle

​Ulla’s designed to fit easily on any bottle, regardless of size or material, with its special silicone mounting band.
No charging

The easily replaceable CR2032 button cell battery lasts up to six months.
