Kardena CARE Life 3 – Health Ring with SOS Function and Sleep Analysis

More safety. More overview. Less worry. Developed for people 55 plus who value peace of mind, independence and simple technology.

“Safety and health as easy as wearing a ring”

The CARE Life 3 works quietly in the background, measures your vital signs, gives gentle reminders and can call for help in an emergency. A daily companion that provides security without any subscription and with data protection by choice (guest mode or encrypted cloud).

Not alone in an emergency

The integrated SOS function can automatically notify a stored contact by call or text message with your location. The alert is triggered by a simple hand gesture when your smartphone is connected.

Understand your health

24/7 monitoring of heart rate, SpO₂, HRV and stress, skin temperature, sleep and activity. The app shows long term trends in a clear way, so you can make calm and informed decisions for your everyday life.

Easy control with touch and gestures

On the outside of the ring you see a discreet white line. This is the touch area. A gentle swipe or tap lets you control functions on your smartphone, for example turning pages or scrolling in an e book, pausing or resuming music or moving through presentations. The gestures are easy to learn, efficient and ideal for older adults. Simple instead of complicated.

Connectivity with Apple Health and Google Fit

The free Aizo Ring app for iOS and Android can connect directly to Apple Health and Google Fit. All measurements are synchronised automatically to give you holistic health management in one place. If you prefer, you can use the ring completely in guest mode, with data stored only on your smartphone.

Discrete reminders

Gentle vibrations remind you to take medication, drink water, move, attend appointments or wake up. There are no loud sounds. A do not disturb setting helps you to sleep without interruptions at night.

Sleep analysis and recovery

Automatic detection of deep, light and REM sleep. A personal sleep score and weekly or monthly overviews help you recognise patterns and develop better habits over time.

Size guide find your perfect fit in about two minutes

For accurate measurements the ring should sit comfortably on the finger, not too loose. Measure the inner circumference of the chosen finger and compare it with the table.

  1. Cut a strip of paper about one centimetre wide and place it around the finger.
  2. Mark the point where the ends overlap, lay the strip flat and measure the length in millimetres.
  3. Compare the value with the table. If your result is between two sizes, choose the larger size.
Ring size Inner circumference (mm) Inner diameter (mm) Note
6 52 16.5 slender fingers
7 55 17.5 ring finger
8 57 18.2 ring or middle finger
9 60 19.1 middle or index finger
10 63 20.1 larger hands
11 65 20.7 broader fingers
12 68 21.7 index or thumb
13 70 22.3 very broad fingers

Tip for accuracy: Measure in the evening when your hands are warm. The ring should turn on the finger but should not wobble.
