We conducted a study to evaluate what apps could people get and what quality these apps were when different searching keywords were used to search in different platforms. We took Stroke apps as an example with "Stroke" "Cerebrovascular Disease" and "Zhongfeng" (in Chinese) as the keywords. Two reviewers evaluated apps independently with revised MARS scale. It was interesting to see that people would get different apps from different platforms with different keywords. The results show that a good mechanism is needed to safeguard people obtain right apps from any source with any term in China.
