Patient Perspectives on a Digital Mobile Health Application for RA.

RA patients appear to prefer task support features in an RA app, notably symptom tracking, appointment scheduling, and reminders, over other features such as those related to dialogue support and social support. The choice of whether an RA app will be free or based on a subscription, pay-per-service, or one-time purchase model may also play a role in eventual adoption. Similarly, physician recommendation appears to influence patients' decision to use an RA app as well as their willingness to pay a subscription for an app.
