The purpose of the study is to investigate how older adults perceive applications for m-health and how m-health applications meet usability factors. And through this be able to analyze shortcomings based on the results. The result will hopefully be useful in the further development of m-health applications in the future. The study has designed theoretical startingpoints based on established usability principles and created an analytical framework for measuring and investigating usability on m-health applications. To measure the principles the study is based on a survey, where the respondents were allowed to express their attitudes. The survey was shared via social media, partly through private messages but also public posts and appropriate groups, where respondents aged 46 and older were requested. The result of the study indicates that the respondents have a relatively good attitude to m-health applications and their usefulness, although there is room for some improvements. The shortcomings that could be identified were partly the visual appearance that some of the respondents considered relatively bland. By analyzing all the principles, it could also be concluded that the structure and findability could be simpler to satisfy a larger part of the target group.
