Applications, often shortened to apps, are software programs that perform some specified set of tasks in a particular hardware environment.

The first "internet app" was the web browser and undoubtedly contributed to its rapid worldwide growth.

One of the first apps on smart phones was the web browser. Despite a lot of popular "native" apps, considerable web browsing is going on. 

We hear a lot of talk about "native" apps... what's that really all about?

CONCLUSION: Lean strongly toward WEB APP unless there is a truly compelling reason to “go native”. And even then, think twice… the landscape changes, sometimes quickly.
