Objective: To identify beneficial experiences, areas needing improvement, and potential additional value, with a view to providing a reference for the application of mobile health management in clinical practice.

Results: Altogether 105 participants having follow-up data at 2 weeks were included, of which 94 were AS patients and 13 were research staff. All participants thought the mini SmartApp was useful, with regard to the scores of PSSUQ between baseline was 1.1 (SD:0.63) and 2-week intervention period was 0.98 (SD:0.53). Four themes emerged from test of usability, participants thought mini SmartApp easy to use and can bring several benefits. However, the theme of needing more useful function revealed that mini SmartApp need further improvement in future use.
