Here’s Why Customers Love Ulla:

Jennifer Montano

This tiny little gadget really works!!! I went from drinking ZERO water per day (literally) to 50 oz just because of my Ulla. There’s something about that little light flashing that truly reminds you to drink when you might now not otherwise.

Secondly I would love to praise their AMAZING customer service. They are truly wonderful. I am happy with the product and happy I chose to support their company. They are great.

After using Ulla at my desk job, my water intake is wayy more than it was before. I’m noticeably more attentive and productive at the office. I get home after work feeling feeling like I have way more energy and have a much easier time getting to the gym… I also don’t see myself reaching for that second $5 ice coffee at 3pm anymore. A MUST HAVE for anyone with fitness goals.

Jordyn T.

I’ve had one for about a year now, and I LOVE it! I frequently get asked what it is, and I love telling folks all about it. My water consumption has definitely increased. I use mine on a Tervis tumbler with a straw, and it still registers my drinking habits. Side note: I haven’t even needed to replace the battery and it’s been over a year.

How will Ulla help me?

One of the easiest ways to feel good and healthy is to stay hydrated. Ulla’s human-­centered design helps you develop the habit of regular hydration. By doing so, it reduces the risk of headaches, improves concentration, raises energy levels, and helps with weight management.

How often will it remind me to hydrate?

Only when you’ve forgotten to take a sip. When it’s been 30-40 minutes since your last drink, Ulla will start blinking for one minute to remind you.

Is Ulla more than just a flashing light?

It’s MUCH more. Behind the casing, you will find a 3-axis high precision accelerometer, ambient sensor, a micro­controller, and a power management circuit. Working together, these make a pocket-sized “smart” device that turns any water bottle into your very own automated hydration coach!

I’m always on the move, carrying my bottle with me. Is Ulla for me?

Ulla was designed for office or home use, so when you carry your bottle around the accelerometer might mistake that for drinking. As a result, it won’t remind you to hydrate as frequently as it would otherwise. However, you’ll still be drinking more water. We’d consider drinking 6 times instead of 2 times a victory.

How should Ulla be attached on the bottle?

Simple! Just wrap the band around your bottle and clip the narrow end of Ulla facing down.

Does it work if I drink through a straw?

All it needs is a little tilt, and Ulla should pick up each sip easily.

What does a day with Ulla look like?

Ulla sits on your water bottle at your desk. When you come to your desk in the morning, Ulla’s vibration sensor detects your proximity and immediately blinks to remind you to refill your bottle with fresh water and drink!

Each 30 to 40 minutes, Ulla will blink again to remind you that it’s time to drink water again. With its integrated drinking detection algorithm, Ulla knows when you drink from your bottle. It only reminds you when you need reminding.
If you pick up your glass or bottle and drink during the hydration cycle (30­-40 min), Ulla’s tilt sensor will recognize that and only remind you when it’s been more than 30­-40 minutes since your last drink.

When you leave the office and there is no movement in the room, Ulla automatically turns off after 2 hydration cycles to save battery.

Will Ulla work at night?

Ulla is designed to go to sleep when you do, and thus will not detect motion in the dark. If you’d like to use it at night, just make sure the lights are turned on.

Will it fit on my large tumbler/mug?

Definately! By clipping Ulla on the included silicone band, Ulla can be mounted on bottles of all sizes and materials.

Does it make any sounds?

Nope. Ulla was created with you and your colleagues in mind, so it’s 100% silent!

How long will the battery last?

You can use Ulla for half a year before even thinking about replacing the battery! When the battery does reach the end of its lifespan, just follow these simple steps to replace it:

1. Take Ulla off the silicone band.
2. Carefully remove the cap.
3. Remove the battery and replace it with a new one, flat side facing away.
4. Wait for Ulla to start blinking continuously for approximately 1 second.
5. Put the cap back on.
6. Clip Ulla back on to the silicone band.
7. Ulla is ready.
