Letter to the Editor

Thank you for your interest and comments. We agree that the global inequalities in terms of access to health care and technology are important matters to be addressed. One of the limitations of our study was that the participants had a very high level of education, and this is often the situation regarding new technology [1]. With the growing use of internet and apps for health issues, more research is needed on the topic of eHealth literacy. To learn more, we are now monitoring the educational level of the users of Tät®, as well as other socioeconomic factors, now that Tät® is freely available in English and Swedish. According to eMarketer,, the global use of smartphones is rapidly increasing. In 2014, 21.6% of the global population used a smartphone; this is expected to rise to 33.3% in 2018. Asia Pacific and China are those world regions with the largest number of new smartphones per year [2]. The number of health apps is growing rapidly, and very few of them are evidence based. In the development of user-friendly health apps, we agree that it is also important to engage users from different countries with different socioeconomic backgrounds.
