About Kardena

Health Technology for Everyday Life

Kardena stands for modern smartwatches, health watches, and healthtech products that make technology understandable and easy to use in everyday life.

Our products are aimed at people who want to monitor their health, activity, and personal well-being more consciously – without having to be a tech expert.

We combine modern sensor technology with the simplest possible operation and functions that offer practical added value.

Our aim: Health technology should support – not complicate.

The History of Kardena

Kardena has its roots in Germany.

The brand was originally established in Bonn and evolved over several years into a provider of smartwatches and health watches for customers in Germany and Europe.

From the beginning, the focus was on functions related to health, activity, and safety.

2026 – A New Chapter for Kardena

In 2026, Armbrüster Consulting GmbH acquired significant assets, brand components, and operational areas of the former Kardena GmbH.

Since then, the Kardena brand has been continued and developed by Armbrüster Consulting GmbH, based in Rastede, Lower Saxony.

Armbrüster Consulting GmbH is not the legal successor of the former Kardena GmbH.

With the acquisition, a new phase of development began for Kardena.

Our goal is to preserve the recognition and experience of the existing brand while consistently developing products, service, processes, and quality management further.

Kardena Today

Today, we focus on the development and distribution of health watches, smartwatches, and other wearables for different requirements and target groups.

Depending on the model, Kardena products offer functions from various areas:

• Heart rate measurement
• Activity and movement tracking
• Sleep analysis
• Blood pressure and health functions
• Notifications and telephony
• SOS and safety functions
• Analysis of health and activity data via smartphone apps

It's not about integrating as many functions as possible into a smartwatch.

What is crucial for us is that functions remain understandable and offer our customers real everyday benefits.

Note: Kardena products do not replace a medical examination or diagnosis. Health functions primarily serve personal information and support in everyday life, unless a product is explicitly designated as a medical device.

Our Mission

Technology can help people to be more mindful of their health.

However, this requires that it is understandable, accessible, and easy to use.

Therefore, at Kardena, we focus on four central principles.

Simplicity

A health watch should not only become understandable after studying an extensive user manual.

That's why we value intuitive operation and comprehensible functions.

Meaningful Technology

Not every technically possible function is automatically meaningful.

We evaluate new technologies based on the actual added value they can offer our customers.

Continuous Improvement

Products and software are not closed projects for us.

Customer feedback, support inquiries, and technical experiences are incorporated into the further development of our products, apps, and documentation.

Personal Benefit

Health data should not just be collected.

They should be prepared in an understandable way and help to better perceive developments and changes in one's own daily life.

---

Our Products

The Kardena portfolio includes various wearables and healthtech products.

A special focus is on our CARE smartwatches and health watches.

These combine classic smartwatch functions with functions related to health, activity, and safety.

Our products are not exclusively aimed at particularly tech-savvy users.

Especially user-friendly operation plays an important role in our product development.

We want to make modern technology accessible even to people who are looking for an uncomplicated health watch for everyday life.

---

Development with our Customers

Many of the best improvements come from experiences in daily use.

That's why we take customer feedback seriously and evaluate recurring questions and support cases.

These insights can, for example, flow into:

• Product improvements
• Software and firmware updates
• New product generations
• Clearer user manuals
• Additional help articles
• Improvements to our apps
• Optimization of our service processes

This creates a continuous cycle of use, feedback, and further development.

---

Service is Part of the Product for Us

For us, the purchase of a smartwatch is not complete with the dispatch of the package.

Especially with technical products, questions often arise only during setup or during daily use.

Therefore, we are continuously expanding our service offerings.

These include, among others:

• Personal customer support
• Digital assistance
• Extensive user manuals
• A growing help and knowledge area
• Support with setup and use
• Information about warranty and returns
• Structured technical fault diagnosis

During the acquisition of Kardena in 2026, existing service processes were also re-evaluated.

Since then, we have been working to further improve processes and provide our customers with faster access to suitable solutions.

We deliberately rely on both digital support and personal contacts.

---

Quality and Product Development

For a health watch, reliability, workmanship, and a comprehensible display of the collected data are particularly important.

Therefore, we continuously develop our requirements for products and suppliers.

Together with our production and technology partners, we are working on, among other things:

• Product quality
• Sensor technology
• Software and firmware
• Battery life
• Usability
• Product testing
• Packaging
• Quality assurance

New products should not only convince through technical data.

For us, it's about the interplay of technology, usability, quality, and suitability for everyday use.

---

Responsibility

For us, responsibility does not end with product development.

As a provider of electronic products, we also deal with topics such as:

• Batteries and rechargeable batteries
• Packaging
• Recycling
• Repair and replacement
• European product requirements
• Environmental and disposal regulations
• Long-term usability of our products

Our goal is to further develop Kardena responsibly and sustainably.

---

Kardena in Europe

Kardena is aimed primarily at customers in Germany and within the European Union.

From our company location in Rastede, we now control essential areas of the brand.

These include:

• Product management
• Product development
• Purchasing and supplier management
• Quality assurance
• Online shop and sales
• Logistics
• Customer service
• Marketing
• Brand development

Kardena products are offered through our own online shop and other selected distribution channels.

Our long-term goal is to develop Kardena into a European brand for health watches and everyday healthtech products.

Preserve the proven. Develop the new.

Kardena reached many customers before 2026 and established itself in the market for health watches.

This history is an important part of the brand.

At the same time, the acquisition by Armbrüster Consulting GmbH does not mean for us simply continuing where we left off.

We want to develop Kardena further.

With new products.
With better processes.
With more understandable technology.
And with a service that is just as important as the product itself.

Our claim for the future is therefore:

Kardena makes health technology more understandable, accessible, and suitable for everyday use.
