Summary of patient feedback from qualitative assessment at baseline (N=18).

App feature and areas of high likeability and usability			Areas lacking and suggestions for improvement		Implications for the patient–HCPa visit
Dashboard
	Provides a clear overall picture of the patient’s knee OAb Creates visual prompts around issues that patients may want to discuss with their HCP, such as pain in relation to activity levels Likely to improve knowledge of OA—allows patients to moderate symptoms and identify limits	Should provide option for adding notes to symptom inputs Include reminders prompting patients to enter their symptoms and ability to enter data retrospectively Text should be enlarged for easier reading		Considered the feature that would be most likely to improve communication with HCPs—prompts patients to discuss issues such as pain and impact on activity levels Receptiveness of HCPs was considered a limiting factor
Goals
	Intuitive and simple to use Useful for encouraging patients to set goals (particularly for those who set goals infrequently); helpful for self-management	Goals were considered likely to work for activity and exercise, less so for symptom management Addition of reminders and a built-in reward system would be helpful Should include a notes feature so that patients can enter specifics on what was done to achieve goals Should link pain reduction goals to resources (less of a goal than an outcome)		Not considered a useful feature as patients do not typically discuss goals with their HCP
Activities
	Easy to update, plot, and review activities; liked the calendar view Helpful to remind patients to complete activities	Feature needs more specificity; should expand categories, for example, add duration to aerobic activities Present information as bullets and enlarge the font size More detailed instructions on how to use the activity feature Some overlap between activity categories (eg, aquatic and aerobic exercise) Link to exercise resources		Not identified as a useful feature for communication with HCPs
Flags
	Provides important visual link to activity avoidance Encourages patients to be more diligent and in tune with their symptoms Helpful for patients to look back on past flags and observe changes over time Helpful for self-management and avoiding or documenting acute episodes	Improve specificity of flags—expand the list of categories so they are more specific Add ≥1 descriptor per flag for improved specificity (eg, pain, low mood, and activity avoidance)		Helpful to note what patients would like to discuss with their HCPs Patients expressed that their HCPs may not be keen on using this feature Logging flags would add validity to the issues patients bring to their HCPs
Information
	Considered the best feature by most patients—particularly the exercise resources Good information from reliable resources	Include SMARTc goals link on the main page Include more strengthening exercises and guidance on exercise for specific patients (eg, with or without mobility issues)		Could help to encourage discussion of local resources and information that are relevant to specific issues
