What is the scope of shiny app, How extensively it is used ?
R Shiny is a great framework for creating analytics dashboards in no time. It has a not-so-steep learning curve and its great for prototyping dashboard ideas, presenting / demoing results.
You can visit the gallery where they have a wide variety of examples ranging from simple to complex.

You need the license though if you want to use it commercially. I think it has great scope.
I have a very different opinion on R Shiny. The learning curve is simple, but you cannot use it for advanced dashboards
- You cannot have multiple bars
- Conditionality cannot be easily implemented at the Sidebar level
- Event handling is not easy when you have not read the entire data into memory before activating the dashboard
