The top five markets for mobile health app companies in Europe include Denmark, Finland, Netherlands, Sweden and the United Kingdom, according to a survey of 5,000 app developers, healthcare professionals, and digital health practitioners. The survey, which was conducted by Research2Guidance in collaboration with HIMSS Europe, found that 55 percent of respondents ranked the UK as the top market.

Respondents were asked to rank the 28 countries in the European Union based on their experiences and explain why they ranked the countries in the order they chose. Other factors that contributed to the ranking include digital health adoption, level of digitalization, market size and health expenditure, ease of starting a business, and the digital health regulatory framework.

According to the survey, the reason the UK ranked above the other EU countries was that doctors in the UK have an open and positive attitude about using new technologies and integrating digital health offerings into patient treatments.

The survey also said that Germany and France have "enormous potential" because of their substantial investments in their doctors and hospitals. But, rankings for digital health adoption in Germany and France were low, "showing these countries are more reluctant to embrace the digitalization of healthcare".

In October 2014, a Berg Insight report found that around 4.7 million people in Europe were using some kind of connected care system by the end of 2013. The report also found that the growth of connected care in Europe is projected to have a 19.2 percent CAGR for the next five years. By then some 13.7 million Europeans will use some kind of connected care system.
