Apps over web sites?
The advantage of an app may be that it makes better (more legible or more convenient to control) use of the limited space on a smartphone or tablet screen than a Web site designed for desktop computers would.
If an app is free (both up-front, and in terms of no "in-app purchase" malarky), why not install it and do the comparison for yourself?
