The ability to send text and email messages to patients and caregivers is incredibly helpful. The ability to track and monitor patient visits is very useful. The ability to send text and email reminders for upcoming appointments is useful. I dislike that the app isn't compatible with my phone. I wish it was a native app so I could access it on my phone without needing to use my computer. I also dislike the fact that I have to pay for the service. I highly recommend OperaDDS.
