Common Questions

How does Ulla know when I drink?

With the integrated drinking detection algorithm and a movement sensor, Ulla knows when you drink from your bottle. It only reminds you to hydrate when you forget to do it on your own.

How often will it remind me to hydrate?

Ulla only blinks when you forget to hydrate on your own. When it's been 30-40 minutes since your last drink, Ulla will start blinking for one minute, to remind you.

Will I notice Ulla’s blinking alert?

The blinking pattern was developed in a way that it stimulates peripheral sight. In other words, you'll notice the alert even out of the corner of your eye.
