Quick access. The four most common requests
If you are unsure: The CARE Pro 6 or Pro 5 are usually the right choice
Many support requests arise because models are compared for too long or because features are missing later on. If you own a smartphone and want a strong all-around choice for prevention, overview, and daily life, two models lead the way: the CARE Pro 6 for people who appreciate particularly simple setup, and the CARE Pro 5 for those who value HRV, AI features, and Bluetooth calling.
App is optional. SOS for up to 5 contacts, ECG, ~7-day battery life. Especially suitable for people aged 60+.
ECG, AI micro-check, HRV analysis, REM sleep, Bluetooth calling. Share data with up to 3 trusted contacts.
CARE GPS for outdoors with dual-band GPS, IP69K, and up to 18-day battery life. CARE Vital 2 as a discreet bracelet without a display, ideal for nighttime.
Note: All Kardena CARE devices are lifestyle products, not medical devices. Displayed values (pulse, ECG, SpO₂, etc.) are for daily orientation and do not replace medical diagnosis or treatment.
Setup: connected your Kardena in five steps
- Install the correct app – you can find the links below or on the Apps page.
- Enable Bluetooth on your smartphone and keep the device within range.
- Important: Do not pair via Bluetooth settings first. The connection is always set up within the app.
- Select Add device in the app and allow all permissions. This is the only way for values and notifications to synchronise reliably.
- If the connection is unstable: Restart both the device and smartphone, then try reconnecting in the app.
- Reset the device to factory settings and pair again.
- Close the app and reopen it. Then update the connection.
- Check permissions: Bluetooth, location, notifications.
- For CARE Vital 2: Disable battery optimisation for the G Band app on your smartphone.
- Check battery level. Low battery can make the connection unstable.
Apps: find the right application
Please only download the app that belongs to your model. You can find the complete overview on the Apps page.
Manuals: Detailed PDFs for all current models
