About Kardena

Health technology for everyday life

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

Our products are designed for people who want to keep a closer eye on their health, activity, and personal well-being—without having to be tech experts.

To achieve this, we combine modern sensor technology with the simplest possible operation and features that offer practical benefits.

Our guiding principle: Health technology should support—not complicate.

The story of Kardena

Kardena has its roots in Germany.

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

From the outset, the focus has been on features related to health, activity, and safety.

2026 – a new chapter for Kardena

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

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

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

The acquisition also marked the beginning of a new phase of development for Kardena.

Our aim is to preserve the recognition and experience of the established brand while consistently continuing to develop our products, service, processes, and quality management.

Kardena today

Today, we focus on developing and selling health watches, smartwatches, and other wearables for a range of needs and audiences.

Depending on the model, Kardena products offer features in a variety of areas:

• Heart rate monitoring
• Activity and movement tracking
• Sleep analysis
• Blood pressure and health features
• Notifications and calls
• SOS and safety features
• Analysis of health and activity data using smartphone apps

Our aim is not to pack as many features as possible into a smartwatch.

What matters to us is that features remain easy to understand and provide our customers with real benefits in everyday life.

Note: Kardena products are not a substitute for a medical examination or diagnosis. Health features are intended primarily to provide personal information and support in everyday life, unless a product is expressly identified as a medical device.

Our mission

Technology can help people take a more conscious approach to their health.

However, this depends on it being easy to understand, accessible, and simple to use.

That is why Kardena focuses on four core principles.

Simplicity

A health watch should not require you to study an extensive user manual before it makes sense.

That is why we prioritize intuitive operation and easy-to-understand features.

Technology that makes sense

Not every feature that is technically possible is automatically useful.

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

Continuous improvement

For us, products and software are never finished projects.

Customer feedback, support requests, and technical experience inform the ongoing development of our products, apps, and documentation.

Personal benefit

Health data should not simply be collected.

It should be presented in an easy-to-understand way and help people better recognize developments and changes in their everyday lives.

---

Our products

The Kardena portfolio includes a range of wearables and health tech products.

A particular focus is our CARE smartwatches and health watches.

They combine classic smartwatch features with features related to health, activity, and safety.

Our products are not intended exclusively for people who are especially tech-savvy.

Clear, easy-to-understand operation plays an important role in our product development.

We want to make modern technology accessible to people looking for an easy-to-use health watch for everyday life.

---

Developing products with our customers

Many of the best improvements come from everyday user experience.

That is why we take our customers' feedback seriously and review recurring questions and support cases.

These insights can inform, for example:

• 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 development.

---

Service is part of the product

For us, buying a smartwatch is not the end of the journey when the package is shipped.

Questions about technical products often arise during setup or everyday use.

That is why we continuously expand our service offerings.

These include:

• Personal customer support
• Digital assistance
• Comprehensive user manuals
• A growing help and knowledge center
• Setup and usage support
• Information about warranties and returns
• Structured technical troubleshooting

As part of the acquisition of Kardena in 2026, existing service processes were also reassessed.

Since then, we have been working to improve our processes and help customers find the right solutions more quickly.

We deliberately combine digital assistance with personal support.

---

Quality and product development

For a health watch, reliability, build quality, and clear presentation of the data collected are especially important.

That is why we continually refine our requirements for products and suppliers.

Together with our production and technology partners, we work on areas including:

• Product quality
• Sensor technology
• Software and firmware
• Battery life
• Ease of use
• Product testing
• Packaging
• Quality assurance

New products should not rely on technical specifications alone to impress.

For us, what matters is the combination of technology, ease of use, quality, and suitability for everyday life.

---

Responsibility

For us, responsibility does not end with product development.

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

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

Our goal is to develop Kardena responsibly over the long term.

---

Kardena in Europe

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

We manage key areas of the brand from our company headquarters in Rastede.

These include:

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

Kardena products are available through our own online store and selected additional sales channels.

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

Preserving what works. Developing what’s new.

Before 2026, Kardena had already reached many customers and established itself in the health watch market.

This story is an important part of the brand.

At the same time, the acquisition by Armbrüster Consulting GmbH does not mean simply picking up where things left off.

We want to develop Kardena further.

With new products.
With better processes.
With technology that is easier to understand.
And with service that is just as important as the product itself.

That is why our ambition for the future is:

Kardena makes health technology easier to understand, more accessible, and better suited to everyday life.
