I always wonder why we still have to pick a doctor's appointment in the old way either by calling the clinic or visiting it or going directly and waiting in line.
I feel that we can create an app that will be great for both the doctors and the consumers. The customers will easily pick an appointment with a specific time slot without having to call or go there. In addition, the doctors will save money because they will not need a secretary anymore to do the arrangement. They could work without a secretary or very limited responsibilities. I had to wait hours in doctors' clinics and I just want an easy way to pick an appointment with a very easy-to-use app.
This is a brief of the idea. There is more if you found it interesting.
