Which device is best for me?
If you use a smartphone and are looking for a powerful all-round solution with ECG and AI analysis, the CARE Pro 5 or CARE Pro 6 is the best choice – both combine health monitoring, SOS functionality, and care sharing features. The CARE Pro 6 is particularly user-friendly: it requires no app and is perfect for a quick start. If you are active outdoors and need GPS tracking, the CARE GPS smartwatch is the best option. For an unobtrusive everyday companion without a display, the CARE Vital 2 health band is ideal.
What is the difference between the CARE Pro 5 and CARE Pro 6 health watches?
Both models are available as Classic (round) or Modern (square) and offer health monitoring, ECG, and SOS functions. The CARE Pro 6 health watch is the newer, 6th generation; it doesn't require an app for basic functions and allows you to set up to 5 SOS contacts. The CARE Pro 5 features AI-supported analysis, HRV monitoring, REM sleep tracking, and Bluetooth calling.
I don't want to wear a smartwatch. Are there alternatives?
Yes. The CARE Vital 2 health band is a discreet wristband without a display that is worn as unnoticeably as a piece of jewellery. It records health data automatically in the background. Available in black, silver, and yellow gold.
Do I need a smartphone for using Kardena devices?
The CARE Pro 6 health watch can handle basic functions like time, steps, pulse, and alarms entirely without a smartphone – the app is optional. All other Kardena models require a connected smartphone (Android 6.0+ or iOS 9+, depending on the model) for SOS locations, notifications, and data analysis. The CARE GPS smartwatch and CARE Vital 2 health band require an active Bluetooth connection to a smartphone for SOS and calling functions.
Are the health measurements medically certified?
No. All Kardena devices are lifestyle products and not medical devices. All displayed values such as heart rate, ECG, blood pressure estimates, or SpO₂ are for orientation and trend monitoring for private use. They do not replace a medical examination or diagnosis.
Questions about setup and usage
How do I connect my smartwatch or health band correctly?
Connection is always made via the appropriate app. Please do not pair the device directly through the smartphone's Bluetooth settings first. Instead, open the app and select Add device there. Grant all requested permissions (Bluetooth, Location, Notifications).
What should I do if the device doesn't connect?
Reset the device to factory settings, restart your smartphone and device, and set up the connection again via the app. Ensure that Bluetooth is turned on and all permissions have been granted. For the CARE Vital 2 health band, battery optimisation for the G Band app should also be disabled.
Which wrist should I wear the health watch or band on?
The device can be worn on either wrist. It is important to set your preferred wrist in the app so that readings remain as consistent as possible. The CARE Vital 2 health band should be worn snugly but comfortably, two fingers' width above the wrist joint – the sensors require skin contact.
Are measurements taken automatically?
Yes, many functions run automatically and continuously, such as heart rate, SpO₂, sleep analysis, stress, and temperature. Some measurements, such as the ECG (on the CARE Pro 5 and Pro 6 watches), are started manually so you can decide when a measurement is useful.
How does the SOS function work?
With the CARE Pro 6 health watch: hold the button down for about 3 seconds → 5-second countdown → message with location sent to up to 5 stored contacts via the connected smartphone. With the CARE Pro 5 health watch: up to 3 trusted contacts. With the CARE Vital 2 health band: tap the side button three times quickly; the connected smartphone will then call the SOS contact. The SOS function does not replace emergency number 112.
How long does the battery of Kardena smartwatches last?
The CARE Pro 6 and CARE Pro 5 typically last around 7 days. The CARE GPS lasts up to 18 days in normal operation (up to 30 days on standby). Charging time for Pro 5 and Pro 6 is approx. 90–120 minutes via magnetic charging cable. Higher display brightness, frequent measurement intervals, and active calling shorten battery life.
Questions about apps and compatibility
Which app do I need for my device?
Each model has a specific app. You can find the overview below. If you are unsure, first check the manual for your model.
Which smartphones are supported?
Android from version 6.0 and iPhones from iOS 9 are generally supported. The CARE Pro 5 and CARE Pro 6 require Android 8.0+ or iOS 13+ for full functionality. We recommend current system versions for stable performance.
Can I share data with family members?
Yes. The CARE Pro 5 watch automatically shares data with up to 3 trusted persons. The CARE Pro 6 watch offers a care-sharing function that you can activate and deactivate yourself at any time. The CARE Vital 2 health band also offers a caregiver feature for optional data sharing with family members via the G Band app.
Are there any app costs?
No. All apps – H Band, G Band, GloryFitPro – are free and do not require a mandatory subscription. The use of the CARE Vital 2 health band via G Band is possible with or without a user account.

A micro airbag for measurement in health watches is a tiny air cushion built into the watches and used to measure various health parameters. These air cushions can contain pressure and motion sensors to capture data such as pulse, blood pressure, sleep patterns, and activity levels. The information is then transmitted to the health watches, giving users insights into their health and fitness. By using micro airbags, the watches can take precise, continuous measurements without being bulky or uncomfortable.

For data protection reasons, the wearer of the watch must first agree to share their data with you. To do this, the wearer must open the app and display their business card.
You can now open your app and scan the wearer's business card. Your accounts are now linked, and you can view the wearer's data in your own app at any time.
