A new generation of bioresonance

About us

In 2012, when Martin Keymer, Dr. Walther Medinger and Dr. med. Peter Kreisl discussed the status quo of bioresonance therapy for the first time, they were unaware of the far-reaching significance of their subsequent technical discussions and the resulting positive impulses for bioresonance devices. But the need for newly created solutions became obvious very soon.

With the founding of the company apere GmbH & Co. KG, the entrepreneurial foundation for an innovative operation in the field of bioresonance therapy was laid. An expert team of scientists and specialists from the medical technology industry successfully worked hand in hand on the implementation of the new bioresonance system: the apere-BMS.


And the successful course continued: With the apere resonator, the company launched the next pioneering and trendsetting development stage on the market just one year later. The patented apere resonator is an exemplary reflection of the high scientific standards of the company. This is because apere relies on know-how and professionalism in the technical as well as the business management area. Its team includes excellent specialists, such as senior electricians and employees with commercial skills.


Since the company was founded in 2015, it has grown steadily, so that in addition to the location in Wendtorf near Kiel, a further branch was opened. As a North German company, apere deliberately decided for a branch in Hamburg, which was taken into service in 2017. In its new office in the Hanseatic city, the apere team is constantly working on new developments. That apere is on the right track is proved by the steady growth of the company.

The People behind apere

Martin Keymer

CEO & Developer 

He is the managing director of the company apere.

As an alternative practitioner he was one of the first in 1982 in Northern Germany to deal with bioresonance. His I.M.U. College is known throughout Germany and beyond its borders. It is thanks to Martin Keymer’s incessant spirit of research that the apere-BMS device is on the market today. He is never satisfied with the existing, but is constantly looking for new ways to enable people to live a healthy life.


Dr. Walter Medinger (✞ 11. 2021)


For years, the Austrian scientist had been deeply involved with the interrelationships between fields and people. He let his technical knowledge flow into the development of apere and had a comprehensive background knowledge of the device: The top-class scientist knew exactly why things in the device are the way they are.


We want to remember our esteemed colleague Dr. Walter Medinger, who was significantly involved in the development of the apere BMS, with honor and gratitude.

Anna-Maria Baresch


The healer and trained curative teacher was called in as a consultant by the three gentlemen during the apere-development. She ensures the medical-ethical basis of apere and focuses on the role of the therapist-patient relationship in the treatment.
