How it works

The Puck works using patented pressure sensing technology, to measure exactly how much you have drunk.

It works best with bottles with open lids or these types of mouthpieces.

Compatible bottles

External pressure changes a lot, so make sure to fill your bottle at least half way when refilling it – the puck will flash so you know it’s registered it.

Some bottles create vacuums when you drink from them, sending pressure a bit crazy. With these types of bottles the reading from your Puck might not be as accurate. We’re working on it.

They tend to have mouthpieces like this.

Incompatible bottles

The Puck

Avoid dehydration, feel more alert and help to reduce weight gain by drinking more water. The Puck creates a personalised hydration target and helps you reach it by gently reminding you to drink throughout the day.

The Puck

Your personal hydration coach

We designed the Puck to remind you to drink when you forget, by glowing in your bottle or sending a notification to your phone. Over time, your hydration habits change and you begin to drink more water.
