CIRCUL
The continuously precise sleep tracker ring

Snoring or sleep apnea?
Around 60% of men and 40% of women start snoring with age. In general, snoring can be harmless, but it can also indicate sleep apnea.
The consequences of sleep apnea.
Sleep apnea has many symptoms such as daytime sleepiness, lack of drive and irritability. However, the constant oxygen undersupply also affects our heart and brain, thereby encouraging high blood pressure, type 2 diabetes and other diseases.

The problem is the loss of control.
After sleep apnea has been diagnosed, not much happens. Control checks are rarely carried out.
The problem is that the influencing factors on sleep apnea are constantly changing. A sleep tracker ring helps you to recognize these changes and to take countermeasures.
1. Measuring
Track your sleep continuously with a sleep tracker ring. Continuity is important here. The sleep tracker ring should absorb your oxygen saturation several times per second.
2. Control
Keep an eye on your measurements continuously. Check the records you made with your sleep tracker ring.
3. Acting
If your values deteriorate, the influencing factors on your therapy may have changed and it is time to act. Show the records to your doctor and have an examination.
My name is Markus Kamps and I have been active in the field of sleep & bed counselling for 25 years. I used the CIRCUL sleep tracker ring myself as well as with my customers and athletes. The ring convinced me as a real professional tool with good data on apnea, ODI, SPO2 and sleep. Combined with high wearing comfort and self-explanatory application, the CIRCUL Sleep Tracker Ring is an ideal tool for sleep tracking.
I will now use it more in our individual coaching sands and for analysis.
This is what our customers say:
