Often there is a lot of time between visits to a doctor or specialist. And in the meantime, a lot can go wrong. Or sometimes you have to go to the waiting room for the umpteenth time when nothing is really wrong. How annoying is this?
It is much better to automatically send important measurements (blood pressure, saturation, heart rate, glucose, ....) to your doctor or specialist at regular intervals. Here you can even send the data from your Fitbit, Apple Watch, etc directly to your doctor, caregiver or caretaker!
