CIRCUL - Sleeptracker Ring

Simple. Continuous. Precise.

Simple on every finger.

The CIRCUL sleep tracker ring was developed with a very specific thought. It should be easy to wear. In order to realize this thought in the best possible way, we focused on ergonomics, flexibility and weight.


CIRCUL is not classically round. It is adapted to the slightly oval shape of the finger and therefore offers a better and more comfortable grip than a classic round.


The ring casing automatically adapts to the size of each finger and thus offers even greater wearing comfort - whether day or night, warm or cold.


The CIRCUL sleep tracker ring weighs only 9.0 grams. This low weight is hardly noticeable on the finger and is therefore not disturbing even when sleeping.

Continuous measuring.

Our vital signs are constantly fluctuating. So they do not hold one value for several hours and certainly not for a whole day. Until now, we have often relied on snapshots. Be it blood pressure, pulse or oxygen saturation. However, every snapshot of our vital signs bears the risk of getting a wrong picture.

This risk can be avoided by continuous measurement. We can detect any fluctuation and determine a meaningful trend of the values. Especially for the sleep analysis this offers an enormous added value.

In the picture you can see a measurement of the CIRCUL ring. The orange points represent a snapshot.
