Most native apps are some half gig large where even the heaviest website is a few mb. They dont let you highlight text and have other bizarre design choices. Even worse, they request importing contacts list which isnt even an option on the web.
Native apps could be butter but more often than not they are like margarine. Smooth, oily, and not good for you.
